Brodiaea californica

I have no trouble with growing Brodiaes in the UK climate. (Derbyshire) Out
of doors it will need a very well drained position, but Summer rain is not
a problem. Undercover they are happy to be very dry from June to November
inclusive. The off setts require some feeding, if in pots, to grow them to
flowering size. I find that, in general, Californian bulbs seem to grow in
the second half of Winter. Eurasian Winter growers generally start rooting
in Autumn.
