Tulbaghia simmleri - genetics?

Hi James,
There are a few diffent white forms of T. simmleri, some are quite weak. I
actually named one that I obtained from California several years ago. I
called it Tulbaghia simmleri 'Cheryl Renshaw' and grown well it is stately
as many good Agapanthus. One of the best Tulbaghia.

Regarding hybrids, there are a few bicolored pink and white forms of T.
simmleri about and these have either been wild selected or crosses between
the pink and the white. I would hazard a guess that if you've enough seed
you'd probably produce one.

This Tulbaghia is one of the least hardy and isn't grown outdoors much in
temperate climates; ideally it wants frost free conditions if grown outdoors
as its seasons of bloom are usually mid-winter and mid-summer. In the UK if
grown in a conservatory you are almost guaranteed flowers on Christmas Day.

In my experience I would say it is shy to produce seed if left to chance;
and probably the least promiscuous of the genus.

Best Wishes,
