Give Japanese pieris moist, well-drained, organic, preferably acid, soil in a site sheltered from drying winds, and keep well mulched. Remove spent flowers. Reliably hardy in Zones 5 to 7, but can be grown with protection in Zone 4b. Own a serviceberry and you'll be fighting the birds for rights to delicious early-summer berries. Serviceberries prefer moist, acidic, well-drained soils but will adjust to almost any soil type.
Berries mature from green to red and are ready to eat when they're a bloomy blackish-purple.
Zones 4 to 9. Tatarian dogwood quickly forms an upright, somewhat open shrub 8 to 10 feet tall, with minimal branching. It also suckers vigorously and small colonies will develop quickly, a pleasant enough feature if you've allowed them room. Give these dogwoods a moist, well-drained site in sun or part shade. They tolerate a huge range of soil types, from acid to alkaline.
