S. lancerottense from the Canaries, S. formosanum from Formosa. 
5. proponticum from Asia Minor has several times died in the open 
with me, and M. Correvon reports that it is not hardy at Geneva. 
To sum up, none of the Mexican Sedums are fully hardy throughout 
the British Isles (though some of them are nearly so). The same 
remark applies to the species of the Japonica series known in 
cultivation, and other Chinese species. The remaining tender 
Sedums found in cultivation are few ; they come from various 
southern regions, and belong to various groups. 
Very little need be said as to propagation. The Sedums are 
notorious for the ease with which any scrap will take root and grow, 
and this applies throughout the whole genus. With the fleshy-rooted 
species, such as S. Telephium, root-cuttings will strike ; and similarly 
pieces of the fleshy caudices of the Rhodiolas will root at once ; the

flowering-shoots of the latter group, if pulled off with a " heel " when 
half-grown, will often strike likewise. 
Another and interesting means of propagation results from the 
capacity possessed by single leaves, when detached, of producing a bud 
and roots from their base (fig. 2), which speedily form a new plant. 
This power is found widely spread in the genus, and equally in terete- 
leaved and fiat-leaved, large-leaved and small-leaved plants: for 
instance, in S. brevifolium, Stahlii, album, reflexum, pachyphyllum, 
diver sijolium, helium, nutans, praealtum, versadense, Treleasei, Tele- 
phium ; even some of the annual or biennial plants — for instance, 
S. indicum — can produce young plants from the leaves, and thus cease 
to be annuals or biennials. I have not observed this power of 
budding in any member of the Rhodiola or Aizoon sections. 
Some of the Telephium section — S. viviparum notably, and also 
its ally, S. verticillatum — produce in the upper part of their annual 
stems numerous small leafy buds which, when the stems fall, root 
. readily and form new plants. Similar short shoots are produced on 
the flowering stems of the N. American S. Douglasii.
