Cultivation
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors at least in the milder parts of the country. There is some confusion over the name, we have used R. arizonicus, but R. arizonensis has also been mentioned. It is possible that these are two different species but we have chosen to put R. arizonensis as a synonym for this species. It requires further investigation. The following notes are based on the general needs of the genus. Easily grown in a good well-drained loamy soil in sun or semi-shade. Plants in this genus are notably susceptible to honey fungus.
Propagation
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. Division in early spring or just before leaf-fall in the autumn.
Edible uses

Material uses
A purple to dull blue dye is obtained from the fruit. A good ground cover plant.
