Here is what I meant to say before I hit "send" early by mistake.

Tulipa humilis 'Albocaerulea Oculata' is a seletion of a species native to 
dryland central Asia, where the soil is
alkaline owing both to geology and to low rainfall.

What plants require varies by site, garden, gardener.

What plants require is not the same as what they will tolerate. Dryland
bulbs are not so much dryland bulbs as bulbs that have evolved through many
difficulties to survive certain conditions. They will tolerate a lot of
drought if they're hunkered deep down in the ground where their roots can
stay cool and faintly moist. They will tolerate rain and more rain if
that water shoots down past their roots.

Tulipa humilis 'Albocaerulea Oculata'  is mass-grown in flat fields in the
Netherlands in soil that is mostly sand, with assiduous irrigation and 
nutrition every year.

But this same tulip makes offsets under very different conditions in my
garden, where the dense, clay-loam soil is acid and rain abates only in

How could these tulips not just survive but multiply in my conditions?

I think it's important that nutrients are not just present but available in
my soil; but it's also important that the bed slopes slightly, which
increases drainage; and that the soil is very porous, making oxygen
available to root hairs.
