Helleborus
xnigercors Helleborus
x nigercors
As with H. x ericsmithii, H. x nigercors
is an interspecies cross which was largely unknown in the US until
the mid 1990's. A hybrid between H. niger and H. argutifolius, the
appearance of the individual plants depends on the parents used to
create the cross. Since there are many forms of H. niger, the
flowers of H. x nigercors may be large and round or small and star
shaped, with numerous intermediates. Foliage may also vary from a
more blued green with few teeth resembling H niger to a very sharply
gray green from the H. argutifolius parent. H. x nigercors has been
a wonderful garden plant in our Zone 7 garden and is reported to be
hardy with some protection in much colder areas. Since this is still
a fairly new plant to American horticulture the full range of
hardiness is not yet known.
As with H. x ericsmithii H. x nigercors is sterile and will not produce
seeds.

Helleborus x 'Snow White' Helleborus
x 'Snow White'

hybrid between H. niger and H x hybridus. Many very
large pure white flowers are borne on each plant.
Produced from tissue culture so each plant is the same. 4' $15.00
qt. $30.00
Helleborus xsternii Helleborus
x sternii
An interspecies hybrid between H. niger and H. lividus and as with the
other interspecies hybrids may vary really depending on parentage. H.
x sternii is root hardy into Zone 6 (and perhaps colder) but the
flowers
suffer in prolonged freezing temperatures. Quite frequently even in our
Zone 7 gardens the foliage freezes off, leaving the flowers blooming on
an empty stalk. When this happens it is perhaps best to cut off the
flower stalk and simply enjoy the summer foliage as one would
with a Hosta or other deciduous perennial.
H. x sternii is fertile and will produce seeds seed strains are very
variable and must be controlled by rouging out any plants which do not
conform to the strain.

Helleborus x sternii 'Montrose' Strain Helleborus
x sternii 'Montrose' Strain
While the foliage of this form is not as silver or gray as some of the
others we have seen, H. x sternii 'Montrose' from nearby Hillsborough
NC
is possibly
hardier.

Helleborus x sternii 'Pine Knot' Strain Helleborus
x sternii 'Pine Knot' Strain
We created this form by backcrossing H.
lividus onto H. x sternii 'Montrose Strain. It has more of the rose
coloring in leaf and flower than Montrose, but not as much as the
English forms.
Hardier?
