Question: I see some shrubs blooming with yellow flowers, but a friend said they were not Forsythia. What are they, and what other April-blooming shrubs are good?
Answer: The shrubs are probably Cornus mas, Cornelian cherry, a relative of the flowering dogwood (despite the name, there is no relation to Cornell University, and it's not a cherry!). The flowers bloom a little earlier and are a little more chartreuse than Forsythia, and the bushes grow bigger, sometimes more like a small tree. In addition, they have red fruits in the summer that are good for jelly, and old bushes may have nicely exfoliating bark.
A tough, old-fashioned shrub is flowering quince, Chaenomeles speciosa. This large shrub is best suited to the back of a shrub border, where it will bloom about the same time as Forsythia. Flower color varies from white to pink to crimson to peach to orangey-red. The rest of the year, it is just a twiggy green mass that may host birdnests and produce a few fruits for preserves. 'Cameo' is a 5' tall variety with peachy-pink double flowers and disease-resistant leaves.
Another April-blooming shrub is the 'PJM' Rhododendron group. These rhododendrons have small evergreen leaves that may turn purplish in the winter. 'PJM' comes in a very bright lavender-pink, while its relative 'April Snow' is white. Like all rhododendrons, they need acid soil, moist but well-drained. However, they are hardy to zone 4 and more tolerant of winter sun than most rhododendrons we can grow.
