About Geranium sanguineum 'Album'

Geranium sanguineum 'Album' · also called White bloody cranesbill, Album bloody geranium · flowering

Geranium sanguineum 'Album' is the pure-white form of bloody cranesbill, forming a loose, spreading mound of finely dissected dark-green leaves. Saucer-shaped white flowers appear over a long season from late spring into summer, with sporadic later blooms. Foliage often colours red in autumn. A tough, sun-loving, drought-tolerant perennial ideal for the front of borders and gravel gardens.

Plant type: flowering

Watch for — Lax, sparse flowering in shade: Too little sun produces a sprawling, shy-flowering plant. Move to a sunnier, more open spot.

The reasons geranium sanguineum 'album' isn't blooming

Almost every non-blooming geranium sanguineum 'album' 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 geranium sanguineum 'album' 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 geranium sanguineum 'album' to flower

  1. Maximise sun. Give geranium sanguineum 'album' 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 geranium sanguineum 'album' and get the feeding right with the geranium sanguineum 'album' 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

Geranium sanguineum 'Album' 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.
