If its of any use to any-one. I tried to germinate the cream Velthemia some years ago and it was a total failure. In 2002 I harvested the seed but forgot to sow it last year, so I wasn't expecting any luck this time. On both occasions I have put them in a layer of fine pumice sand on top of my usual bulb mix.This time I sowed them late summer Feb 26th I think and they germinated like grass on Mar 18th. During this time I have had minimums of 13-17C and maximums of 19-29C. Malcolm Redwood. Napier, New Zealand. Zone 9.
