Most of the first flowers to bloom in spring are called “ephemerals” because they appear as the earth warms, then die back after blooming. They will return year after year if the conditions suit them. Tulips are usually replanted annually because the bulbs rot in the northeast climate. However, daffodils return and multiply. Tulips, daffodils and hyacinths and allium are planted as bulbs in autumn.
The Hellebores are in a class by themselves. They bloom in the late snows of spring and their foliage stays green year round. Hellebores prefer shade and are a good choice for urban gardens. You can see many hellebores blooming in March and April.
