Growing Camassia Bulbs

Camassia is a genus of summer flowering bulbs that naturalises well in gardens. The leafless flower spikes have blue and occasionally violet or white star shaped flowers.

Culture and Growing Tips

  • The plant thrives in moist conditions in meadows, alongside streams and near ponds.
  • The soil needs to be high in humus, not waterlogged and otherwise the plant is easy to grow   forming  big clumps.
  • Camassia may be divided in autumn after the leaves have withered.
  • Bulbs should be planted 4″ deep in the autumn. Additionally the plant spreads by seed.
  • Leaves are slow to die down when grown in grass.
  • Flower spikes range from 1′ to 5′ tall dependent on variety.
  • Grow nfrom fresh seed or offsets from around the main bulb
