Allium schubertii

Pamela,

I have never really tried to seed A. schubertii, but it has done a good
job all on its own in my garden. I have it growing in a combination of
sand and the native clay soil in Cologne on a sloped bed. It received
more than 4 hours of sun most days, but it doesn't really get a baking
in Summer, just a drought period right after blooming. Along with A.
christophii, seedlings abound among the roses and take about 4 years to
bloom for me. A. christophii is certainly the better spreader and often
creates clumps where the seed heads have fallen. A. schubertii sometimes
skips a year blooming for me and I only see leaves. I have the feeling
it is somewhat sensitive to wet conditions during its rest and during
Winter, as whole patches of seedlings will disappear come Spring. This
could be mice, as well.

Hope this helps a bit,
