Hellebore - Helleborus

Nodding cups of white, yellow, pink, green, purple or violet open while the rest of the garden stands bare. Hellebore, the Christmas rose, is the winter-flowering perennial par excellence, hardy down to about 5°F (-15°C); give it part shade out of direct sun and it will flower on for many long years.

Planting hellebore

It is often advised to plant hellebore in fall, ideally sometime in November but you can plant it until spring as long as it doesn’t freeze.

Since hellebore only flowers after 1 or 2 year, the earlier you plant it, the earlier you can savor its bloom!

Proper planting is the key to having your hellebore thrive for many long years.

  • Avoid direct sun and select a spot that is partly shaded, perhaps with sunlight either in the evening or in the morning.
  • Enrich your soil with special perennial, flower plant or all-purpose soil mix and, eventually, add a soil conditioner like manure or seaweed or home-made compost.
  • Let the clump sit in a bucket of water before planting it to the ground.
  • Plant the hellebore with the blend of garden soil and soil mix you prepared.
  • Space plants by about 12 inches (30 cm).
  • Water abundantly.

If ever the need arises to move your hellebore to a new spot, proceed preferably in spring and extract the largest possible clump, because hellebore doesn’t like being transplanted.

Pruning and caring for hellebore

Caring for hellebore
Strip spotted and withered leaves as buds appear

Easy to care for, hellebore doesn’t bloom until the second year after planting. It needs time to settle in.

When buds appear, eliminate wilted, spotted or withered leaves, especially for the Helleborus niger variety.

Once it has started bearing flowers, you can remove wilted flowers regularly (deadheading) to trigger appearance of new buds.

To make your hellebore even more beautiful, you can also remove damaged leaves to highlight the beauty of its flowers.

For potted hellebore, it is necessary to regularly add fertilizer because the substrate quickly loses its nutrients in pots.

  • The key to success is to use a deep pot!

Which hellebore to choose

Hellebore is not a single plant but a group of species that differ in flowering time, colour and temperament. This table sums up what the article says about the ones most often grown.

Which hellebore to choose
Species Also known as Flowering What sets it apart
Helleborus foetida Stinking hellebore From late autumn, on through winter Hardy and at home in forest underbrush
Helleborus orientalis Lenten rose Winter into early spring The most varied for colours and shapes; easy to care for
Helleborus nigercor Hybrid of ‘niger’ and the Corsican hellebore Abundant, over many long months Foliage stays green all year round
Helleborus niger Black hellebore, the original Christmas rose Winter The hardest to grow; dislikes very acidic soil
Helleborus purpurascens Violet hellebore Among the first to open Purple underside to the petals
Helleborus veridis Green hellebore Winter Evergreen, with luminous green flowers matching the leaves

Growing several together stretches the display from late autumn right through to the beginning of spring.

Hellebore key points to know

Hellebore is a perennial that blooms beautifully. It will flower repeatedly throughout the winter season until the beginning of spring, most often from November to March and April.

If it doesn’t bloom during the first year, this is perfectly normal, since it usually needs two years to unveil its cute little flowers.

In a flower bed or a garden box, hellebore, also called “Christmas rose“, will know how to appeal to you with its pastel-hued petals that are pink and white.

Hellebore will grow year after year and you’ll enjoy seeing its cute white, yellow, pink, green, purple or violet flowers as jewels in your garden or terrace.

It is very hardy, since it can withstand freezing down to about 5°F (-15°C).

All in all, hellebore presents a great many advantages, since it is very ornamental, unique, and flowers for a long time. Caring for it isn’t a hassle, either!

Hellebore interesting species and varieties

Varieties of hellebore
Mixing varieties stretches flowering into early spring

Without necessarily launching a complete hellebore collection, it makes sense to have several varieties so that shapes and colors can complement each other.

If you have multiple hellebore varieties, you can extend the blooming season from November all the way to the beginning of spring: the ultimate winter-blooming flower!

Whether they be wild, hardy, early or late bloomers, every hellebore is unique and will make you proud of every single square foot planted with them.

Remarkable hellebore species

  • Helleborus foetida – This hellebore variety is quite at ease in forest underbrush, is quite hardy and usually blooms as early as November, and continues doing so all winter long. See pictures of it here.
  • Helleborus orientalis – Certainly one of the most common cultivars, this lenten rose is also one of the most varied in terms of colors and shapes. Easy to care for, the only attention it needs is to remove damaged leaves one by one.
  • Helleborus nigercor – It got its name from the hybridization of its two parents, the hellebore ‘niger’ and the Corsican hellebore. Its foliage stays green all year round and it still is able to offer abundant and plentiful blooming for many long months.
  • Helleborus niger – Also called the black hellebore, this plant is probably the most difficult hellebore to grow. It doesn’t like very acidic soil. It is the original Christmas rose.
  • Helleborus purpurascens – Also called the violet hellebore, it is one of the first to bloom. The purple underside of its magnificent petals is amazing.
  • Helleborus veridis – Also an evergreen hellebore, its flowers match its leaves and are a luminous green color.
  • Helleborus hyemalis – Also called dwarf hellebore, winter hellebore, and winter aconite. It has the special trait of remaining small and produces very cute yellow flowers. Recently renamed to Eranthis hyemalis.
