About Heuchera 'Plum Pudding'

Heuchera 'Plum Pudding' · also called Coral Bells 'Plum Pudding', Alumroot 'Plum Pudding' · flowering

Heuchera 'Plum Pudding' is a classic perennial with deep, metallic plum-purple foliage featuring a distinctive silver overlay. Slender stems bear small pale-pink flowers in late spring and early summer. Hardy and drought-tolerant once established; excellent as ground cover or a container accent in partial shade.

Mature size: 25-35 cm tall (foliage mound); flower scapes to 50 cm

Indoor size vs how big it gets in the wild

Heuchera 'Plum Pudding' grows into a room-scaled plant of roughly 25-35 cm tall (foliage mound) — bigger than a tabletop plant, but not a tree. Indoors and in a pot, expect 25-35 cm tall (foliage mound). In the ground with no restriction it is a completely different plant — flower scapes to 50 cm — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It builds steadily in both height and spread to a medium, manageable size, filling a pot and a corner over a few years.

Growth rate and years to mature

Heuchera 'Plum Pudding' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: one application of slow-release balanced fertiliser in early spring is usually sufficient for established plants in good soil. in containers, apply a dilute balanced liquid feed monthly from april to august to compensate for nutrient leaching.
