[I want] some advice about growing Allium and Fritillaria in pots.

Many small species of these genera are often grown in pots... and
also in hypertufa troughs, which offer a bigger root run and better
temperature and moisture control.

...you will have to place the pots in a sheltered location,
plunged in some substance that will keep the moisture and
temperature constant during their dormant period. They won't
tolerate the kind of baking they'd get in above-ground pots in your
area, especially in sun...

I don't think there is any Allium or Fritillaria that definitely
can't be grown in a pot, as long as you control the water regime
properly and don't let them desiccate or boil in summer.

Perhaps it is worthwhile recounting the system that Molly Grothaus
used to grow her Frit collection in -- was it Lake Oswego, Oregon? --
somewhere in the Portland area. She gave a talk on this at one of the
western winter study weekends in the early 1980's, and (like Paul
Christian's talk around the same time on bulb propagation) I still
have vivid memories of some details.

Molly (Mollie?) grew her frits in upended pottery flue tiles, which
her husband, a building contractor, could buy fairly reasonably in
quantity. Each species went into its own tile. The tiles were
arranged in an elongated block (memory is uncertain here) of which
one end was shaded by a tree in the garden.

When she lifted and replanted her frits in the summer, if she noted
that a given species was looking withered, she'd replant it a
little closer to the tree, thus in somewhat cooler, shadier
conditions. Each species would find its own niche with just the right
balance of shade and sun after a few years.

IIRC, she was trying to acquire the entire genus and had an amazing
range of species in her tile bed.

Perhaps pbs subscribers who knew Molly and her garden at first hand
can give us more details?
