The sand cherry (Prunus pumila v. bessyi) is a drought-tolerant shrub that typically grows 3-5 feet in height - though our relatively shallow growing medium might limit that.

Sand cherries have lovely white flowers in spring and semi-edible fruits in summer (as in they're very tart and might need processing to be palatable - and it's possible that if the seeds are eaten you might experience some unpleasant side effects).

cherries, this is what they'll look like!
But it's a tough, attractive shrub that is great for pollinators, so here's hoping it'll keep up the good growth!

PS - there was a happy little bumble bee (Bombus huntii) foraging on a Sharpleaf Twinpod today too!
