Hi Khoas,
The flaccida and simplex I got from Fred Howell. I am sure you know him. The nephrophylla is froom Triffid Park. I picked it up at there moving sale back in March or April. I haven't yet seen flowers from any at this stage, so I cannot gaurantee until this occurs but that is the name they were purchased under.
You may be interested to know that Triffid Park are moving into a new nursery and will be having an open day on the 9th of November. These are always good days when you can wlak through there new settup and buy plants. The VCPS will also be there and generally provide some kind of demonstration and a giveaway but there have been no details of this at this stage. I have posted link below.
