Camassias are one of the most underrated bulbs for a brilliant display in the Spring and early summer.
I have photographed them in positions within a border in full sun, in meadow areas where they are happy to naturalise in long grass, and in the dappled shade of woodlands.

In each position, they have all seemed happy.
There are only a handful of Camassia to mention - all with the same cultural needs for care and growing. Main colours are either white or blue, held aloft on leafless 'flower spires' of around 24in.
This is variable, for some clumps or Camassias within the clumps seemingly just 6-10 in tall. this adds to the attraction for me, for then you have a much more interesting clump than if all the flower spikes were the same height.

Camassias originate from damp meadowland land in the north USA, but as with many bulbous plants, seem to be quite happy - certainly in the short term - in most areas of the garden other than full shade.
