Grow helleborine in moist soil that does not dry out. Shops also call the western native stream orchid or chatterbox, and some tags say Giant Hellebore — it is still this orchid, not a winter hellebore.
Give it moist soil that does not dry out, and part shade
| Factor | Recommended | Avoid |
|---|---|---|
| Light | Part shade, or sun only if the soil stays wet | Do not site it on a hot, dry west wall |
| Soil | Moist, humus-rich soil that still has an outlet | Do not plant in a sealed puddle, or in bone-dry sand |
| Water | Keep the bed evenly moist through the growing season | Do not let the bed crust dry in summer |
| Place | A stream margin, pond edge, or moist woodland | Do not grow it in indoor bark mix, or in a dry perennial border |
This is a hardy terrestrial orchid with creeping rhizomes. Site it where the soil stays moist and still has somewhere for extra water to go. It is not a plant for a dry border, and it is not a plant for a sealed, stagnant hole. [1] giant helleborine and broad-leaved helleborine want that same moisture. Pick a kind on Types of Helleborine. Set the rhizome on Planting Helleborine.
Part shade is the usual garden site. Give it more sun only when the soil stays wet, as it would along a stream or a pond margin. [2] Work leaf mould or compost into that moist bed. An indoor bark pot on a windowsill is the wrong mix. [3]
Does helleborine need full sun?
Part shade is the usual garden site. Give it more sun only if the soil stays wet, as it would along a stream.
How wet should the soil stay?
Evenly moist, with an outlet. Do not let the rhizomes sit in a sealed puddle, and do not let the bed go bone-dry.
Grow it in a pot only to keep the rhizomes from spreading, or if you have no moist bed
A pot is a hold, not a houseplant job. Use a draining pot of loam-based mix and keep it moist through the year, including winter rest. A small indoor bark pot is the wrong mix. [4]
- Choose a pot with a drainage hole. Fill it with loam-based mix, not bark chips.
- Keep the mix moist even when the leaves have died back. A dry pot in winter is how the rhizome fails.
- If you already grow the weedy woodland kind, sink that pot in the bed so the rhizomes cannot run into the lawn.
Can I grow helleborine in a pot?
Yes, in a draining pot of loam-based mix, kept moist even in winter rest. A small bark orchid pot is the wrong mix.
Keep the soil moist while it grows, then ease off after the leaves die back
Water through spring and summer so the soil stays evenly moist, not crusted dry and not stagnant. After flowering, the leaves yellow and die back. Cut that watering back. Resume when new shoots appear.
- Water in dry spells while leaves and spikes are up. Do not let the bed crust dry, and do not flood a hole with no outlet.
- When the foliage yellows, stop soaking. Leave the dying leaves until they pull away. The rhizome is storing food for next spring, and there is no pruning job beyond that.
- Skip a heavy fertilizer program. A spring mulch of leaf mould is enough. Rich, manured soil grows weeds that smother the orchid.
Do I water helleborine in winter?
Ease off after the leaves die back. Keep a pot from going bone-dry, but do not soak a dormant rhizome in a cold, sealed puddle.
Not a hellebore, and not a lady's slipper
A hellebore is How to Grow Hellebores — a buttercup-family plant with winter flowers, not a summer orchid spike. A hardy lady's slipper is How to Grow Lady's Slipper — a woodland orchid with an inflated pouch, not a cup-shaped lip on a leafy stem. Marsh helleborine is still this genus. It is not the marsh orchid on How to Grow Marsh Orchid.
Is this a hellebore?
No. Hellebore is a winter-blooming perennial in the buttercup family. Helleborine is a terrestrial orchid with a leafy summer stem.
If the bed has gone dry, water it this week and add a leaf-mould mulch — do not wait for next summer's missing spike.
FAQ
Do I need fertilizer?
A spring mulch of leaf mould is enough. Do not pile manure on the crown. Weeds in rich soil crowd the orchid out.
Can I dig one from a stream bank?
No. Buy nursery plants raised from division. Wild plants are often protected, and they usually die after a move.
I found this in my lawn — is it a weed?
Broad-leaved helleborine can take over lawns and beds in much of the eastern United States. Dig the whole rhizome if you do not want it, and check your county before you plant that kind.
