About London Pride
Saxifraga umbrosa · also called London Pride, St Patrick's Cabbage · flowering
London Pride is a tough, shade-tolerant evergreen perennial forming rosettes of leathery, spoon-shaped leaves. In late spring it sends up airy sprays of tiny pale-pink flowers on slender red stems. Reliable and low-maintenance, it thrives in moist, well-drained soil and is an excellent ground-cover for shady borders and rockeries.
Plant type: flowering
The reasons london pride isn't blooming
Almost every non-blooming london pride 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 london pride 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 london pride to flower
- Maximise sun. Give london pride 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 london pride and get the feeding right with the london pride 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
London Pride 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 london pride care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.
