Rubus squarrosus

Fritsch

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[

General Information

Rubus squarrosus is an evergreen shrub with two distinct growth habits. When growing amongst taller vegetation it produces stems that can be 10 metres or more long and scramble into the surrounding vegetation; when growing in the open it is more likely to be of bushy growth with densely interlacing branchlets. The stems can be extremely prickly or unarmed and, when growing in the open, the plant is usually leafless (or nearly so) with the green stems carrying out photosynthesis and flowers seldom produced[

Cultivation Details

Rubus squarrosus is found through much of New Zealand, growing into the lower montane zone where it can experience snow and frost. It dislikes harsh winters, though, and is only hardy in the milder regions of the temperate zone. It succeeds outdoors in the milder parts of Britain, where it makes a small shrub, though even then it is best grown against a sunny wall[

Prick out the seedlings when they are large enough to handle and grow on in a cold frame. Plant them out into their permanent positions in late spring of the following year.
Cuttings of half-ripe wood, mid summer in a frame[
