Helleborus
We list a wide range of Helleborus seed, both from the garden hybrids and from the wild
species of this small genus in Ranunculaceae with about 15 species, mainly in southern Europe and
the Caucasus. All seed we list is collected in the current year. As Helleborus species of
Section Helleborastrum cross indiscriminately in cultivation, open-pollinated garden seed of
these is useless for raising correctly named plants. Authentic material from wild colonies is
essential if the genuine species is to
be grown. Failing this, hand-pollinated seed from segregated cultivated plants of known wild
origin is a second best. We usually offer wild-collected seed, largely through the efforts of
our friend, Will McLewin, who not only regularly collects in southern Europe himself but also arranges
collections by local botanists in Croatia, Montenegro, Russia, Georgia and Ukraine.
We have been involved with raising garden hybrid hellebores for many years and list an
extensive range of seeds from The current year’s seed should be sown in summer as soon after harvest as possible, placed outside at normal outdoor temperatures and kept moist. We usually have fresh seeds cleaned and ready to send out by July each year. Seed sown late, after the weather has cooled down in autumn, may not germinate until the following winter. Soaking seed in hot, not boiling, water and leaving it at room temperature for a day before sowing may help germination the first winter. Hellebore seed germinates at low-temperatures. Keeping seed warm after sowing will inhibit germination. Many of the wild hellebores are plants of continental climates, used to snow-cover in winter and dry conditions in summer. Consequently, they are not always so easy in wet, temperate climates, such as that of Britain. Choose a well-drained site for the central and eastern European ones. The garden hybrids, influenced by H. orientalis from the moister, Black Sea area, are much more accommodating. Nomenclature : We follow the standard work, 'Hellebores' by Brian Mathew (1989), but it must be appreciated that the names in this are only a reasoned compromise. The species of Section Helleborastrum seldom comply with the main diagnostic criteria used to divide them into the artificial concept of 'species'. Flower colour, free or joined carpels, overwintering leaves and especially leaf characteristics are not consistent features. Most colonies are extremely variable and there is a great deal of intergradation. Such problems are being considered in an ongoing series of articles by Brian Mathew and Will McLewin in 'The New Plantsman'. Further information : : 'Hellebores' by Brian Mathew (1989) is the best source of information on the wild species. ‘The Gardener’s Guide to Growing Hellebores’, a publication aimed at a wider gardening public, edited by Graham Rice and Elizabeth Strangman (1993) follows the nomenclature used in this. It includes a chapter by Jim Archibald on hybrid hellebores and ones on the species by Will McLewin and Brian Mathew. As this genus is currently fashionable, there are several other less significant books on hellebores. |
