Cardamine pentaphyllos, the five-leaflet bitter-cress or showy toothwort, is a flowering plant in the family Brassicaceae, native to Western and Central Europe in Slovenia and Croatia. It is an herbaceous perennial, growing to 30–50 cm (12–20 in), with palmate leaves and racemes of purple, pink or white flowers in late Spring and early Summer. The Latin specific epithet pentaphyllos means "with five-lobed leaves". The feminine form pentaphylla is sometimes seen, but this is deemed incorrect. This plant has gained the Royal Horticultural Society's Award of Garden Merit.

Propagation

Sow seed in spring in a cold frame; germination typically occurs within 1–3 weeks at 15°C. Once large enough to handle, prick seedlings into individual pots and grow on in light shade in a greenhouse or cold frame for the first two years, planting out when dormant in late summer. Divide in early spring or after the plant dies back in summer. Larger clumps can go directly into permanent positions, while smaller ones should be potted up and grown on in a cold frame until well rooted before planting out in spring.
