Heart shaped raspberry grows in wild only and has not been brought under cultivation yet. However, expert observations of this shrub indicate that it might be easy to grow this plant on well drained loamy soils in sun or semi shade.
New plants can be raised from seed. The germination is enhanced if the seed is cold stratified at 3 C for a month.
