Sedum pallidum (Crassulaceae) – alien species of the flora of plain part of
Ukraine
Introduction
The timely detection of new alien plant species
is a contemporary pressing issue. During the
acclimatization and naturalization, many alien
plant species escape beyond the places of
cultivation and replenish synanthropic flora.
The number of escaped plants has increased
rapidly in recent decades, causing modern
concerns (Protopopova & Shevera, 2012, 2013;
Shynder, 2019b). The family Crassulaceae J. St.-
Hil. is characterized by the great diversity of
cultivated species. Many species of the family
naturalize and form secondary synanthropic
ranges (Byalt, 2011). Sedum pallidum M. Bieb
belongs to such species, widely handled as
an ornamental plant throughout the plain
part of Ukraine and is prone to naturalization.
There is no reliable information about the
naturalization of S. pallidum in Ukraine, so the

Abstract
The objective of this study was to evaluate the current distribution of Sedum pallidum in Ukraine, to analyze
its state in the alien flora of Ukraine.
Material and methods. The studies were conducted in 2008–2019 in the plain part of Ukraine and the
Crimean Mountains. Literature information, several national herbarium collections, and other sources
were analyzed. Special attention was paid to the delimitation of synanthropic locations of S. pallidum from
cultural ones.
Results. S. pallidum is a sub-euxine species, which range occupies the Crimean Mountains. It is widely
cultivated throughout Ukraine and is prone to naturalization, thanks to its vegetative and generative
reproduction. In general, about 30 synanthropic locations of S. pallidum have been recorded, mainly in the
Middle Prydniprovia and Western Ukraine. Urban lawns and roadsides on light substrates are favorable
ecological niches for S. pallidum.
Соnclusions. S. pallidum is the alien species in the flora of the plain part of Ukraine and ergasiophyte in
its origin. A potential secondary synanthropic range of this species occupies the whole country except
the Carpathian highlands. It has been established that S. pallidum in the culture of the Forest-Steppe is a
perennial herb. Two races identified in its composition (var. pallidum and var. bithynicum) are probably ecads
and have no systematic importance. In the culture, S. pallidum is characterized by successful vegetative
and generative reproduction, which contributes to its naturalization. S. pallidum is often confused with
other species of the genus, which does not contribute to its study in adventive floras. A key for S. pallidum

establishment of a synanthropic range of this
species is relevant. Hence, the objective of this
study was to clarify the current distribution of
S. pallidum in Ukraine and to analyze its state
in the alien flora of Ukraine.
Material and methods
The floristic and comparative-morphological
studies of S. pallidum in the natural,
introduction, and synanthropic habitats were
conducted in 2008–2019 in the plain part of
Ukraine and the Crimean Mountains. Some
plants were introduced to the M.M. Gryshko
National Botanical Garden of the National
Academy of Sciences of Ukraine for further
exact determination. Herbariums of KW,
KWHA, KWU, LWS, and LWKS (see Index
Herbariorum (Thiers, 2020) for abbreviations),
literature and other sources were analyzed to
summarize the chorological information (Wulf,
1960; Shynder et al., 2018; Shynder, 2019b;
UkrBIN, 2020).
Classification of groups of alien plants is
provided with respect to published sources
(Protopopova & Shevera, 2012; Shynder, 2019a).
An important task was the separation of the
synanthropic habitats of S. pallidum from the
places of its cultivation. As we showed before
(Shynder, 2019a), artificially planted plants
after abandoning care of them (so-called
“relicts of culture”) should not be attributed to
spontaneous habitats. Sometimes plantations
of S. pallidum sprawl and form a carpet cover
over a large area, which is similar to the
spontaneous population, and the flowerbed
itself may not exist. But the cultural origin of
such colonies can be identified by the remains
of old beds and other representatives of the
cultural flora. As synanthropic (adventitious),
we refer to those populations, which were
located at some distance from flowerbeds
and composed of many individuals and their
groups, often covering a large area (sometimes
several dozens of ares).
Results and discussion
Sedum pallidum is a sub-euxine species with
a range covering the Crimean Mountains,
the southeastern part of the Balkan
Peninsula, Asia Minor, the South Caucasus,
North-Western Iran and Cyprus (Wulf,
1960; Chamberlain & Muirhead, 1972; Byalt,
2001; Hart & Eggli, 2003). In the Crimean
Mountains, S. pallidum is at the northern
limit of its natural range. Here, according to
herbariums data, literature sources (Wulf,
1960), and our own field observations, we
have identified 70 locations of the species that
outline the Crimean part of its range (Fig. 1).
Most of the Crimean locations of S. pallidum
are concentrated in the western part of the
main mountain range. In other parts of the
Crimean Mountains, the species occurs only
sporadically.
The natural habitats of S. pallidum are
attributed to rocky substrates with moderate
moisture – rocks, scree, and sometimes
occur in light forests. Comparing with the
Figure 1. Natural locations of Sedum pallidum on the Crimean peninsula.
Plant Introduction • 85/86 77
Sedum pallidum (Crassulaceae) – alien species of the flora of plain part of Ukraine
close species S. hispanicum L., the habitats
of S. pallidum are moister (Wulf, 1960; Byalt,
2001). The species is widely cultivated in many
countries of the Holarctic as a ground-covering
perennial plant and is prone to naturalization.
S. pallidum often occurs wild in Southern
Scandinavia and Central Europe (Byalt, 2011;
Bomble & Wolgarten, 2012; Hohla, 2018).
In Eastern Europe, this species sometimes
escapes beyond the places of cultivation (Byalt,
2001). It is also naturalized in China and Japan
(Byalt, 2011). Probably one of the adaptations
of S. pallidum to the successful growth in
conditions of high humidity is guttation. In
the condition of Kyiv, guttation in S. pallidum
is quite pronounced in comparison with other
species of the family. It happens even when it
is not observed in other species.
The biomorphological characteristics of the
species differ among published sources. Wulf
(1960) attributed S. pallidum to annuals and
biennials. A number of authors distinguish two
biomorphological races within S. pallidum s.l.:
a) the annual typical var. pallidum (= subsp.
pallidum) with or without few shoots,
which are never wintering; b) the perennial
var. bithynicum (Boiss.) D.F. Chamb. (= subsp.
bithynicum (Boiss.) V.V. Byalt) with numerous
sterile wintering shoots. Only annual plants
are described for the Crimean Mountains
(Chamberlain & Muirhead, 1972; Byalt, 2001).
Byalt (2001) attributed S. pallidum to annuals
or biennials. He described both races as
cultivated plants in Eastern Europe and noted
that subsp. bithynicum is cultivated more
often. Hart & Eggli (2003) placed S. bithynicum
in synonyms to S. pallidum and characterized
the species as perennial. The authors also
noted that all sterile shoots could periodically
form inflorescences, and in this case, the
plants become monocarpic.
We tend to regard S. pallidum as a
vegetatively mobile herbaceous perennial that
forms monocarpic generative shoots and is
prone to particulation. In 2007 and 2008 we
introduced living plants of S. pallidum from
different locations of Crimean yaylas to the
M.M. Gryshko National Botanical Garden NAS
of Ukraine. All plants have taken roots well and
for several years have formed a thick carpet
in which sterile wintering shoots prevailed
numerically; in the following year, some of
them have formed generative shoots (Fig. 2).
Generative shoots wither after flowering, often
together with nodes of tillering (especially in
the conditions of drought). This fact leads to
the particulation of the maternal individual.
However, in the situation of sufficient
moisture, the lower part of the withered stems
can persist and become a short-lived rhizome.

Probably, in conditions of dry habitats of the
Crimean Mountains, plants could not always
be able to form a sufficient number of sterile
shoots. In Crimean habitats that we observed,
S. pallidum plants formed mainly generative
shoots and were not prone to intense
vegetative overgrowth. Thus, the plants of
S. pallidum from the Crimean geographical
population are only facultative annuals, if they
are at all. Hence, the races identified within
S. pallidum are not independent taxonomic
units but simply ecads.
In the conditions of Kyiv, cultivated plants
successfully produced self-seeding. Seedlings
appear in September and October, and the
rosette size increases before winter. Thus, in
the Forest-Steppe conditions, S. pallidum is
characterized by successful vegetative and
generative reproduction. The rapid vegetative
sprawl and attractive greenish-glaucous color
of the vegetative parts contributed to the
popularity of S. pallidum for the landscape
of the large areas, primarily for municipal
sites. In places of cultivation, S. pallidum is
characterized by durability and often extends
on adjacent areas, where it successfully
anchors.
Despite the fact that S. pallidum has become
a trivial species in urban landscapes, it was
not usually cited in the lists of the alien flora
of cities and regions of Ukraine until recently.
However, after the revision of herbariums
and published material, it was found that
S. pallidum was sometimes reported, but under
other names (Kagalo et al., 2004; Kuzyarin,
2012; Doyko & Katrevych, 2015).
The list of secondary synanthropic locations
of S. pallidum in the plain part of Ukraine is
given in the Appendix.
Also, we have repeatedly registered
persistent colonies of cultural origin near
abandoned or existing places of S. pallidum
cultivation and flowerbeds. For example, we
noted such colonies in Rudnytsia (Vinnytsia
region), Rzhyshchiv (Kyiv region), Kaniv, Smila,
Talne, and Uman (Cherkasy region, in all
cases in parks), Dzhankoy (Crimea). It should
be noted that the locations of S. pallidum,
obviously of introduction origin, were also
found in the seaside part of the Southern
coast of Crimea (according to O.F. Levon).
Still, the secondary range of this species can
be separated from the natural one only in the
Steppe Crimea.
Thus, nowadays, there are about 30
synanthropic locations of S. pallidum, most
of which are recorded from the Middle
Prydniprovia and Western Ukraine (Fig. 3).
Urban lawns and roadsides on sandy and
other light substrates are the favorable
ecological niches for S. pallidum. Their
regular mowing promotes the vegetative
dispersal of the species (especially in regions
with sufficient moisture) and eliminates
competition from tall herbaceous plants. The
most of synanthropic S. pallidum locations
were recorded in similar habitats, where the
species was at the stage of the beginning of
an expansion. In some other ecotopes, for
example, on railway embankments, sandy
roadsides of forest roads, around the edges of
forests, S. pallidum was rarely recorded and
was only at the stage of initial expansion and
fixing. In all the cases, curtains and colonies
of S. pallidum developed successfully on well-
aerated substrates.
Today, there is every reason to believe
that S. pallidum participates in floras of
all large and many medium-sized cities of
Ukraine as an adventitious element. So, the
potential secondary synanthropic range of this
species covers the whole Ukraine with except
the Carpathian highlands. But outside of
urbanized landscapes, not all areas of Ukraine
can be suitable for S. pallidum naturalization.
For example, in the southern lane of the Right-
bank Forest-Steppe, S. pallidum occurs in a
culture quite rarely, and we have not noticed
any of its synanthropic habitat. The rarity
of S. pallidum in the culture of this terrain is
explained by the absence of large cities and the
prevalence of traditional landscaping methods
on agrarian areas (without rockeries and
carpet flowerbeds). In addition, the ecological
conditions of the southern strip of the Forest-
Steppe (with soils of heavy texture, lack of
atmospheric moisture, frequent dominance
of turfy steppe and tall adventive plant
species in ruderal ecotopes), probably much
less favorable for S. pallidum naturalization
comparing to the northern strip of the Middle
Prydniprovia and Western Ukraine.
Thus, S. pallidum is an ergasiophyte in its
origin, which in current conditions, became
a part of the adventive flora of Ukraine. The
first synanthropic finding of this species
dates to 2001, so according to the time
of immigration, it is eukenophyte – alien
Plant Introduction • 85/86 79
Sedum pallidum (Crassulaceae) – alien species of the flora of plain part of Ukraine
species that has come since the end of the
XX century (Protopopova & Shevera, 2012).
In synanthropic habitats, by the degree of
naturalization, S. pallidum participates as a
typical colonophyte (species that form stable
local populations in synanthropic habitats).
In some urban floras, such as floras of Kyiv
and Lviv, it demonstrates a tendency to
expand further and gradually goes into a
group of epekophytes (species that have fully
naturalized in anthropogenic habitats). At the
moment, S. pallidum should be considered
as an unstable element of flora. But, in some
urban areas, this species is already sufficiently
entrenched in many secondary ecotopes and
is a potentially expansive species. Due to its
current distribution and ecological features,
S. pallidum can be widely spread in the
ruderal and semi-natural ecotopes of Polissya
and Western Ukraine in the future. In more
arid regions with fertile soils (Chernozems),
its distribution will probably remain localized
and will correlate with urban areas.
To clarify the species composition of the
regional adventive floras, florists should pay
attention to S. pallidum. In many cases, it is
also necessary to check the correctness of
determination of Sedum specimens preserved
in collections. As noted above, this species
was widely represented as the escaped plant
in our flora, but often misidentified with
S. album, S. hispanicum, and S. lydium. After
acquaintance with many private and scientific
collections in Ukraine, we concluded that
S. pallidum is one of the most common species
representing the genus Sedum. Still, it is mostly
unnamed, or it is provided under wrong names
in such collections. S. pallidum is officially
listed only for two collections of arboretums
and botanical gardens, while S. lydium is
mentioned for seven collections (Mashkovska,
2015). Taking into account that we have never
(!) met living plants of S. lydium (at least in the
flowering stage), we can assume that it is a
result of numerous misidentifications.
Identification of Sedum s.l. can be
problematic. Thus, the Asian S. lydium is
mostly not included in published floras and
identification keys in Europe. Byalt (2001)
attributes S. pallidum to annuals or biennials,

which sometimes also lead to doubts during
identification. As noted above, in the ecologic
conditions of the plains part of Ukraine,
S. pallidum develops as a perennial plant.
Since S. pallidum has so far been confused
with S. album, S. hispanicum, and S. lydium,
we outlined the main features distinguishing
these species (Fig. 4).

Sedum pallidum (Crassulaceae) – alien species of the flora of plain part of Ukraine
During the flowering period, distinguishing
these species is generally not a problem.
In general, S. pallidum is a widespread
ground-covering plant that forms light
greenish-glaucous curtains, sometimes with
anthocyanin (purple) spots, and inflorescences
are always glandular-pubescent. S. hispanicum
is a glaucous-green, often with a gray and
anthocyanin-burgundy tinge; it is a glandular-
pubescent annual plant, which does not
sprawl, and is rare in collections. S. album
is a widespread perennial that forms dark
green carpets, often with a burgundy tinge (or
entirely burgundy, but not purple). S. lydium
is close to the S. album, and is characterized
by dense, brighter green curtains and often
red lower leaves or reddish tips on the upper
leaves. Researchers should pay attention
to that S. album and S. lydium are entirely
glabrous plants. Distribution of S. lydium in
culture in Ukraine requires further critical
study. According to literature sources, this is
a rather widespread species in culture (Byalt,
2001; Mashkovska, 2015), but those sedums
that we have observed in private collections
under identifications of S. lydium and S. lydium
‘Glaucum’ were found belonging to S. pallidum.
Conclusions
Sedum pallidum is an alien species and an
unstable element of the flora of the plain
part of Ukraine, an ergasiophyte in its origin.
It is widely spread in the culture throughout
the country. It has been established that
S. pallidum in a culture of the Forest-Steppe
is a perennial herb, and two races identified
in its composition (var. pallidum and
var. bithynicum) are probably ecads, which are
out of systematic importance. In the culture,
S. pallidum is characterized by successful
vegetative and generative reproduction, which
significantly supports its naturalization. In
the urban floras of Kyiv and Lviv, this species
tends to expand and becomes an epekophyte,
but in most other regions, it is at the stage of
colonophyte. In collections and floristic lists,
the name S. pallidum is widely wrong adduced,
which leads to confusion. Hence, we developed
the key for the identification of S. pallidum.
The potential secondary synanthropic range
of this species occupies the whole country
except the Carpathian highlands.

Мета – з’ясувати сучасне поширення Sedum pallidum в Україні, проаналізувати його стан у складі
чужорідної флори України.
Матеріал та методи. Дослідження проведено у 2008–2019 рр. на території рівнинної частини України
та у Гірському Криму. Проаналізовані літературні відомості, фонди кількох вітчизняних гербаріїв
та інші джерела. Особливу увагу приділяли відділенню спонтанних місцезростань S. pallidum від
культурних.
Результати. S. pallidum – субеквксинський вид, ареал якого охоплює Гірський Крим. Широко
культивується по всій Україні і схильний до натуралізації, розмножуючись вегетативно і генеративно.
Загалом зафіксовано біля 30 спонтанних місцезнаходжень S. pallidum, переважно у Середньому
Придніпров’ї і Західній Україні. Сприятливою еконішою для S. pallidum є міські газони та узбіччя
доріг на легких субстратах.

Negrash, Y.M. The objective of this study was to evaluate the current distribution of Sedum pallidum in Ukraine, to analyze its state in the alien flora of Ukraine. Material and methods. The studies were conducted in 2008–2019 in the plain part of Ukraine and the Crimean Mountains. Literature information, several national herbarium collections, and other sources were analyzed. Special attention was paid to the delimitation of synanthropic locations of S. pallidum from cultural ones. Results. S. pallidum is a sub-euxine species, which range occupies the Crimean Mountains. It is widely cultivated throughout Ukraine and is prone to naturalization, thanks to its vegetative and generative reproduction. In general, about 30 synanthropic locations of S. pallidum have been recorded, mainly in the Middle Prydniprovia and Western Ukraine. Urban lawns and roadsides on light substrates are favorable ecological niches for S. pallidum. Соnclusions. S. pallidum is the alien species in the flora of the plain part of Ukraine and ergasiophyte in its origin. A potential secondary synanthropic range of this species occupies the whole country except the Carpathian highlands. It has been established that S. pallidum in the culture of the Forest-Steppe is a perennial herb. Two races identified in its composition (var. pallidum and var. bithynicum) are probably ecads and have no systematic importance. In the culture, S. pallidum is characterized by successful vegetative and generative reproduction, which contributes to its naturalization. S. pallidum is often confused with other species of the genus, which does not contribute to its study in adventive floras. A key for S. pallidum determination has been proposed. Мета – з’ясувати сучасне поширення Sedum pallidum в Україні, проаналізувати його стан у складі чужорідної флори України. Матеріал та методи.
