Heuchera 'Plum Pudding' (Coral Bells 'Plum Pudding') is grown for its richly colored foliage and tidy, mounding habit. You get a dense clump of ruffled, plum-purple leaves with a subtle silvery sheen, plus airy stems of small, bell-like white flowers in late spring to early summer. At maturity it typically sits in the 10-20 inch tall range (taller in bloom) with a compact spread that works well at the front of borders, along paths, or as a color anchor in mixed containers.
Plant it where you can give it part shade for best leaf color, especially in warmer climates. Provide moist, well-drained soil and avoid sites that stay soggy in winter. A light layer of mulch helps even out moisture, but keep mulch off the crown. Water regularly the first season to establish a strong root system; after that, aim for evenly moist soil and water during prolonged dry spells.
For simple upkeep, remove tired or winter-damaged leaves in early spring as new growth begins. Deadhead flower stems if you prefer a cleaner look, or leave them for a softer, airy effect. Divide crowded clumps every few years to refresh vigor. Use this plant to add deep color contrast with chartreuse or silver companions, and tuck it into shaded borders where you want dependable foliage interest.
