Rubus leucanthus

Hance

Rosaceae


The genus Rubus, (especially the blackberries, which are often loosely referred to as Rubus fruticosus agg.) presents some of the most difficult taxonomic problems. This is partly due to the frequency of polyploidy; also to the frequent occurrence of hybridization; and also due to apomixis, where minor differences between plants are preserved because seedlings are genetically identical to their parent. As a result, differences of opinion on the number of species to be recognized from a given region can vary tremendously (for example, a treatment by M. L. Fernald[

Stored seed requires one month stratification at about 3°c and is best sown as early as possible in the growing season. Prick out the seedlings when they are large enough to handle and grow on until large enough to plant out.
