Perhaps I should say that in my dry chalky garden the few allium
unifolium are slowly declining. The invaded garden, where I introduced
them, is a heavy clay soil wet in winter, but now just starting to crack
up after a month with no rain. Both triquetrum and unifolium have seeded
in many hundreds, and in the latter case in a bed where I worked
manually through the soil only 2 years ago to clean it they are now back
and very healthy sized, probably from small bulbs I missed. Snowdrops,
camassia leichtliniii, leucojum aestivum, erythronium pagoda and dens
canis, fritillaria imperialis, the larger allium hybrids, and colchicum
hybrids all grow well there.

Some of the local woods around here are beginning to change from green
to blue with sheets of bluebells (English), another invasive plant when
it gets into the garden, even in my dry soil. A national survey of the
Spanish and English bluebells is commencing as the former is suspected
of interbreeding and dominating the local race. Note the bluebells of
Scotland, from the song, are campanula rotundifolia.
