Caltha- Marsh Marigold, Kingcup

The single-flowered form occurs wild in Great Britain. It is a hardy perennial.

Situation:

In containers round garden ponds; also in marshy spots. Will thrive both in full sun and in partial shade. The striking flowers appear early in the year.

Soil:

Neutral or slightly acid soil, not too poor and, of course, very damp.

Propagation:

Mature clumps are easily divided. Caltha can also be raised from seed.

Caltha palustris: Height 25-50 cm; flowers in mid to late spring, sometimes for a second time in the autumn. The flowers are single, bright yellow; the foliage is bright green. Garden varieties are ‘Multiplex’ with double flowers; and ‘Monstruosa’, a strain with even larger double flowers of unusual shape.
