They make showy garden additions, and the most popular varieties have flowers that bloom on arching stems in spire-like clusters, hence the name. Because they lose their leaves every year, spirea are not considered an evergreen plant.

Does spirea stay green year round?

Is spirea a perennial? Spirea is perennial in the sense that it comes back each year. But it is more correctly known as a shrub because its woody branches persist above ground all year round, and in spring, the new growth emerges not from the ground but on those branches.

Do spirea keep their leaves in winter?

All Spireas are deciduous and lose their leaves in the winter. Most bloom between March and May in our area. Some varieties will produce a second set of flowers if the worn out blooms are pruned off.
