Cultivation details

Easily grown in a good well-drained loamy soil in sun or semi-shade[11, 200]. Plants have biennial stems, they produce a number of new stems from the perennial rootstock each year, these stems fruit in their second year and then die[200]. Often cultivated for its edible fruits in America, it is the parent of many named varieties. Plants in this genus are notably susceptible to honey fungus[200]. For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a running thicket former forming a colony from shoots away from the crown spreading indefinitely [1-2]. The root pattern is flat with shallow roots forming a plate near the soil surface [1-2]. The root pattern is suckering with new plants from underground runners away from the plant [1-2].
