Toad lilies in Spain: a difficult plant for cool shade

Toad lilies, Tricyrtis, are shade perennials from the woodlands of eastern Asia, grown for small orchid-like flowers, usually white heavily spotted with purple, carried along arching stems in late summer and autumn. They are lovely plants, and this needs saying plainly: they are difficult on the Costa Blanca and easy only in the small number of gardens that can give them cool, constantly moist, humus-rich shade.

Why they struggle here

Everything Tricyrtis wants is difficult to maintain in a typical south-east Spanish garden. It needs humus-rich soil that stays moist but drains, plus shelter from hot drying wind in full or partial shade. The species tolerates a wider soil pH than is sometimes claimed, but heat, low humidity and drought stress scorch the leaves and check growth. In an exposed or sunny position it is unlikely to persist.

Where it can work

The plant is worth trying if you have a genuinely shaded, north-facing courtyard or a bed under dense evergreen canopy with irrigation, ideally in a cooler inland or higher-altitude garden rather than on the hot coastal plain. In those conditions it can form a slowly spreading clump that flowers when little else in the shade is active.

Growing it in a pot

For most people a large container is the realistic approach. Use a peat-free loam-based compost with added leaf mould, stand the pot in deep shade and never let it dry out or sit waterlogged. Feed lightly in spring and move the pot to the coolest sheltered position available for summer.

Care

Cut the old stems down in late winter. Divide congested clumps in early spring. Slugs and snails are the main pest and will shred the emerging shoots, so protect new growth. Do not expect the trouble-free spreading ground cover that generic growing guides describe.

The honest bottom line

If you have the shade and water, Tricyrtis is a rewarding late-season plant. If you do not, the same corner is better given to plants adapted to a Mediterranean climate.
