Hellebores - Propagating and Varieties
(continued)
Hellebores
From Seed
Many Hellebores self-seed very easily and if you can find seedlings
near the parent plant, dig them up in early autumn or late spring and
replant them where needed.
One key factor with
Hellebore seed is that it is at it's best when fresh - after 8 weeks
or so, the germination rate will begin to deteriorate rapidly. So, if
you can collect your own seed and use it quickly, that is best.
Collect the seed in late spring / early summer time. The sides are
ripe when the pods start to dry out and then begin to split open.
After picking the seed pod, shake out the seeds and separate them from
any of the pod debris. Sow as soon as possible after
There are
also many nurseries which sell
hellebore seed and the specialist ones generally ensure that the seed
is fresh. However, it is best to ask for yourself. Click here for a
few nurseries across the UK which have been recommended.
Sow
the seed in
July, in 12.5cm (5in) pots filled
with a 50/50 mixture of John Innes Seed compost and any good
multi-purpose compost. Cover the seed with a thin layer (no more than
1 cm) of washed grit or vermiculite. The pots should be left outside
in the shade during the warm weather and if pests prove a problem, cover them something.
Ensure that the compost remains moist but not soaking wet.
The
seedlings will not appear until
mid-autumn
time at the earliest and
may well not appear until
March
the next year. With Helleborus
foetidus, the seedlings will often take as long as two years to
germinate. Note also that Helleborus vesicarius will die back after
producing a few leaves and you may think it has died - it has not! It
will reappear the following
November.
As soon as the seedlings appear
uncover them and in a few weeks prick them out into individual 12.5cm (5in) pots
filled with John Innes No 2 (70%), washed grit (15%) and multi-purpose
potting compost (15%).
The plants will need
feeding from about six weeks after potting them up and should be
repotted when they become pot bound.

Hellebore Varieties
Almost without exception, all
Hellebores make excellent plants. Our particular favorites which can be
found in many nurseries are listed below.
Helleborus orientalis (or
hybridus)
Evergreen
perennial with green divided foliage. The flower colour depends on the
variety - white, pink and purple being the most usual. Click on the
left hand picture to enlarge it.
The flowers appear in late winter
to early spring, and on plants five or more years old, there are often
50 or more flower stems.
A real 'stunner' at a time of year
when the garden is sorely lacking sophisticated colour.
Height and spread is 45cm (18in),
they prefer partial shade and are fully hardy. Expect these plants to
live for 15 years or more. Not available as seed, purchase as a pot
plant - readily available from nurseries.
Helleborus foetidus
This
hellebore is a native of Britain, and is extremely well adapted to cooler
climates. It is more short-lived than many other Hellebores, but will be
an exceptional plant for five years or more. Click on the picture to the
right for a larger version.
This is an evergreen perennial
with dark green divided foliage. Be aware that the name 'foetidus'
indicates that scent of the flower is smelly to put it mildly!
The flower colour is a pale green,
with some varieties (notably 'Wester Flisk') having a red rim to the
flower. The flowers appear in late winter to early spring, occasionally
coming in to flower at Christmas. Helleborus foetidus definitely
benefits from cutting back the old foliage to the ground in June to
encourage new growth throughout the year.
It readily self-seeds, and after
five years, the parent plant should be replaced by one of the seedlings,
which will produce flowers the next year. Height and spread is 45cm
(18in), they prefer partial shade and are fully hardy. Purchase as a pot
plant - readily available from nurseries.
Helleborus argutifolius (or
corsicus).
A
great hellebore to grow because it self-seeds so easily. It has lovely
evergreen glossy leaves with spiky edges.
The flowers are pale green /
yellow and appear in bunches of six or more. very attractive and
unusual. An extremely easy hellebore to grow, it will even self-seed in
between paving slabs!
After years or so, replace with
one of the seedlings which you are bound to find elsewhere in your
garden.
Helleborus sternii
