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.

Plant type: flowering

The reasons heuchera 'plum pudding' isn't blooming

Almost every non-blooming heuchera 'plum pudding' traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding heuchera 'plum pudding' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get heuchera 'plum pudding' to flower

Maximise sun. Give heuchera 'plum pudding' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for heuchera 'plum pudding' and get the feeding right with the heuchera 'plum pudding' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Heuchera 'Plum Pudding' flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full heuchera 'plum pudding' care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.
