About Goldmoss Stonecrop

Sedum acre · also called Goldmoss Stonecrop, Wall Pepper · flowering

Sedum acre is a vigorous, mat-forming stonecrop native to Europe, Asia, and North Africa, widely naturalised in North America. Its tiny, succulent, triangular leaves form a dense moss-like mat covered in a bright flush of star-shaped golden-yellow flowers in late spring and early summer. Extremely tough and drought-tolerant, it colonises walls, rock gardens, and alpine troughs.

Plant type: flowering

Watch for — Aphid attack on new growth: New spring growth and flower stems can attract aphid colonies. Blast off with water or treat with a fatty-acid insecticidal soap. The problem is usually transient as populations build slowly on such small foliage.

The reasons goldmoss stonecrop isn't blooming

Almost every non-blooming goldmoss stonecrop 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 goldmoss 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 goldmoss stonecrop to flower

Maximise sun. Give goldmoss stonecrop 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 goldmoss stonecrop and get the feeding right with the goldmoss 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

Goldmoss 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.

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

Goldmoss Stonecrop blooming — frequently asked questions

Why won't my goldmoss stonecrop flower?

Goldmoss 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 goldmoss stonecrop bloom?

Give goldmoss 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.
