Campanula incurva

Or at least, that's what I think it is - no label I could find

That's enough for now.  I'll try to continue tomorrow with pictures from the alpine houses, and from the specialist societies event.

Cyanella hyacinthoides

This is a South African bulb which I have grown from seed and flowered myself, though my plants were not as lush as these, and I lost them subsequently.

Allium dichlamydeum

A choice onion species from California - another I have loved and lost.

Calochortus

There were several pots of calochortus in the display house.  I don't know whether they were grown from seed, or arrived as bulbs, but unfortunately, the majority seemed to be mis-named.  I am far from an expert on Calochortus, and haven't had the time to dig out Mary Gerritsen's excellent book on the genus, so this is the best I can do.

The first two photos were labelled Calochortus species - looking at the photos on the Pacific Bulb Society website, I think these are probably C. superbus.  The chocolate blotch outlined in yellow seems to be reasonably diagnostic.

The next pot was labelled C. gunnisonii, but I am not convinced.  With similar blotches, I think these are either C. superbus, or a hybrid involving that species.

A third pot was labelled C. kennedyi which it is clearly not.  C. kennedyi is a desert plant from extremely low rainfall areas, and as a consequence very difficult to grow.  Typically it has fabulous bright orange flowers.  There were two different forms growing in this pot - the first (lilac) looks as though it might be C. venustus, the second (white) is either C. superbus again, or a form of the very variable C. venustus.
