Epimedium
Epimedium × versicolor
Quite possibly the best plant there is for dry shade under trees, and consistently under-planted because it is unremarkable in a pot on a garden centre bench. Delicate spurred flowers in April on wiry stems, heart-shaped leaves that colour bronze, and complete indifference to root competition once established.

Nothing to do
No sowing, planting, harvesting or pruning window falls in August.
Coming next month: plant, divide.
Epimedium’s year
Resolved for United Kingdom (general). Every window is stored against a climate event rather than a date, so a late frost pocket runs later than the band shows. What else August calls for.

Timing that travels
The band above resolves this plant's windows into months for one region. These are the windows themselves, stored against a climate event rather than a date — which is the form that survives being carried to a colder garden, a frost pocket, or next year.

On your soil
Computed by comparing this plant's recorded requirements against each soil's recorded characteristics. A recorded horticultural fact overrides the comparison where GrowingHQ holds one.
| Soil | Verdict | Why |
|---|---|---|
| Heavy clay | Works, with one condition | Epimedium will crop on heavy clay, but one thing has to be dealt with first. It needs ground that drains, and this soil holds water. A plant that stays in the ground through winter with its roots in cold, saturated soil rots — which is what kills most of what fails on heavy ground, rather than the cold.Improve the drainage before planting — a raised bed, or bulky organic matter worked in over several seasons. Do not add sand to clay in small quantities; it makes the problem worse. |
| Sandy | Prefers this soil | Sandy suits Epimedium as it stands: The pH suits it: it wants 5.5 to 7.5, and this soil is in that range. The free drainage is exactly what it wants. It stands dry conditions better than most, which this soil will test. |
| Chalky and alkaline | Prefers this soil | Chalky and alkaline suits Epimedium as it stands: The free drainage is exactly what it wants. Chalky soil is among the soils it is recorded as suiting. It stands dry conditions better than most, which this soil will test. |
| Loam | Prefers this soil | Loam suits Epimedium as it stands: The pH suits it: it wants 5.5 to 7.5, and this soil is in that range. The free drainage is exactly what it wants. Loam is among the soils it is recorded as suiting. The soil holds moisture, which saves a great deal of watering. |
| Silty | Prefers this soil | Silty suits Epimedium as it stands: The pH suits it: it wants 5.5 to 7.5, and this soil is in that range. The free drainage is exactly what it wants. The soil holds moisture, which saves a great deal of watering. |
| Peaty and acid | Works, with one condition | Epimedium will crop on peaty and acid, but one thing has to be dealt with first. It needs ground that drains, and this soil holds water. A plant that stays in the ground through winter with its roots in cold, saturated soil rots — which is what kills most of what fails on heavy ground, rather than the cold.Improve the drainage before planting — a raised bed, or bulky organic matter worked in over several seasons.

| Shallow over rock | Prefers this soil | Shallow over rock suits Epimedium as it stands: The free drainage is exactly what it wants. Loam is among the soils it is recorded as suiting. It stands dry conditions better than most, which this soil will test. |
| Made ground and urban soil | Works, with one condition | Epimedium will crop on made ground and urban soil, but one thing has to be dealt with first.

Growing it
- PruningCut all the old foliage off at ground level in February, before the new flower stems appear. The flowers are held low and are completely hidden by last year's leaves if this is not done — it is the difference between a plant that seems to do nothing in spring and one that is charming, and it takes five minutes.
- PlantingWater it through its first two summers even though it is a drought-tolerant plant. Establishing anything in dry root-filled shade is the hard part; once its own roots are down it needs nothing at all, and it will still be there in twenty years.
