About White Stonecrop

Sedum album · also called Coral Carpet · flowering

White Stonecrop is a low, spreading evergreen succulent with plump, cylindrical green leaves that flush coral-red in heat and cold, crowned by clouds of white summer flowers. A classic green-roof and rockery groundcover, it is exceptionally drought- and cold-hardy, roots from the smallest fragment, and is ASPCA non-toxic to cats and dogs.

Plant type: flowering

The reasons white stonecrop isn't blooming

Almost every non-blooming white stonecrop traces back to one of these, roughly in order of how common they are:

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

Feeding white stonecrop 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 white stonecrop to flower

  1. Maximise sun. Give white stonecrop the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
  2. Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
  3. Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
  4. 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 white stonecrop and get the feeding right with the white stonecrop 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

White Stonecrop 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.

White Stonecrop blooming — frequently asked questions

Why won't my white stonecrop flower?

White Stonecrop blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make white stonecrop bloom?

Give white stonecrop the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.

When does white stonecrop normally bloom?

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

What should I do with white stonecrop after it flowers?

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.

What is the single biggest mistake stopping white stonecrop flowering?

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