some Veltheimia bracteata

I can confirm that in my experience the colour of the collar or neck of
the bulb is a very good indication of the likely flower colour provided
the bulb gets some light. If the neck is underground it can become
blanched and mostly white. Bright green necks mean a flower with no red
in it. Tinges of pink or red pigment indicate the flower will be pink or
rose in colour. That is the experience I have had with dozens of bulbs
grown from seed.

Thanks for that insight, Pieter. It seems a number of plants that have
yellow or white flower morphs also have foliage that lacks characteristic
red tinge or markings. I've seen some euphorbias like this.

Someone did mention to me once that white and/or yellow V. capensis has been
seen. Maybe it was Ernst van Jaarsveld. Any intrepid collector (like Ernst)
would have gathered it if at all possible, maybe it was an inaccessible
plant or was lost in cultivation. Something to dream of!
