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[
] in 1950 recognized 205 species for the northern half of the eastern United States plus parts of southeastern Canada, whilst H. A. Gleason and A. Cronquist in 1991 recognized only 25)[
]. Where possible, a relatively conservative approach is taken here[
Common Name: Bush Lawyer
Rubus moorei is a vigorous, evergreen shrub, producing a cluster of prickly, biennial stems from a woody rootstock; given the support of other vegetation, the stems can scramble for several metres[
The plant is harvested from the wild for local use as a food.
Australia - New South Wales, Queensland
]. Subtropical rainforests[
Rubus moorei is native to the warm temperate and subtropical regions of eastern Australia.
Species in this genus are generally easily grown in a good well-drained loamy soil in sun or semi-shade[
Plants in this genus are notably susceptible to honey fungus[
There are two types of plant, one with hairy and one with smooth stems[
Fruit - raw or cooked and used in pies, preserves etc[
]. A delicious tangy flavour but it contains a lot of hard seeds which can be annoying[
]. The red fruit is up to 25mm long[
Seed - requires stratification and is best sown in early autumn in a cold frame. Stored seed requires one month stratification at about 3°c and is best sown as early as possible in the year. 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[
Tip layering in July. Plant out in autumn.
Division in early spring or just before leaf-fall in the autumn[
