PLANT
OF THE MONTH: February 2006
Hellebores
There has been an upsurge
in popularity in hellebores in recent years with the introduction
of new and exciting forms and colors. Betsy Clebsch gave us a
refresher course on the various species in general use as well
as a look at some of the unusual cultivars she is growing in
her garden. Although hellebores are European natives they seem
to be made to order for Californian gardens; they are gopher
and deer proof, they are shade-loving but tolerant of alkaline
soil, and give us a long period of bloom in winter just when
we need them. They are tough plants and will survive poor soil
and drought but really perform best with good soil and regular
water.
Helleborus xorientalis
is the species most often grown here and is the one with the
greatest display of color, from white through pinks and purples
and, recently, shades of yellow. Flowers may be clear or variously
spotted or speckled. Hybridizers are now producing ever more
vivid colors as well as double forms. Betsy showed a pure white
double called 'White Magic' and an especially nice apple blossom
combination of white petals with pink rims. This species is stemless,
the petioles and flowering stem rising directly from the roots.
Although the leaves will hang on into the second year they are
best removed in fall so that the new flowers and stems can be
seen to better advantage.
H. argutifolius
is one of the largest of the hellebores, 2 to 4 ft. high, 3 ft.
wide, and has handsome foliage, gray-green, the three-parted
leaves leathery and spiny-edged. The leafy stems are topped with
clusters of cup-shaped creamy-green flowers, as many as 20 or
more flowers per stem.
H. lividus resembles
H. argutifolius, is native to Majorca and rarely seen
in nurseries here. It is distinguished by blue-green three-parted
leaves that have lighter veins and pinkish-green flowers and
petioles. A cross between lividus and argutifolius
is H. xsternii, an especially handsome and vigorous
plant with flowers and leaves intermediate between its parents.
Its seedlings sometimes favor one, sometimes the other parent.
It is available from Suncrest Nurseries.
