Plant of the Month
Hybrid hellebores (Helleborus x hybridus) are very tolerant and will grow well in most soils as long as the ground is not extremely dry or stagnantly waterlogged, although they usually survive even those conditions. They prefer a sheltered position in semi-shade (dense shade can reduce flowering) with a rich, moist, free draining soil. If possible, it is desirable to plant hellebores on a sloping bed, both to improve drainage and also to make it easier to look into the flowers, which naturally nod. Flowering between January and May, depending on climate, hellebores are prized for their sturdy, undemanding temperament and the striking colors. All hellebores are deer proof. Northwest Garden Nursery Wholesalers are open to the public for viewing and purchase, from 10am to 5pm, Saturday and Sunday, February 19-20, and February 26-27.
