Over the past few months, I've acquired several species of small Utrics. Because I'd like to collect seed where possible and also want to avoid having unwanted seed scattered among other species pots - I would like information on the pollination requirements for different species. I'll start by listing the information I've found (not necessarily accurate - feel free to differ). If there are sources where this information is available - please share ...
U. subulata - weed that requires no pollination intervention & often sets seed without even flowering (cleistogamous flowering)
U. bisquamata - sets seed without intervention - freely spewing seeds into nearby pots
U. bisquamata 'Betty's Bay' - manual pollination required
U. sandersonii ('normal' bunny ears) - free flowering but will not produce seed - even if manually pollinated
U. sandersonii 'blue' - ??
U. graminifolia - ??
U. livida - ??
U. blanchetii - ??
U. parthenopipes - ??
U. warburgii - ??
U. uniflora - ??
U. tricolor - (not that I'll ever get a bloom) 8^) - ??
U. nephrophylla - ??
