Now I remember it George, sorry. It is just one of a packet of mixed colours which came free with a magazine some years back. I can only remember that they were dwarfer than the normal types and labelled G. primulinus hybrids.
The G. byzantinus properly should be called G communis ssp,byzantinus. The one which I used to grow came from wild collected seeds, but I am almost positive it has gone now.
The G. carinatum (I think) is another one grown from seed, and it spreads itself arouind too
I am not that fond of the hybrids, but some of the original species are lovely. Silverhill Seeds (I think) used to sell seeds of some of them.
We have tried growing one called G. flanniganii (or summat like that) without much success. I do have a picture somewhere from a show.
Now if you start on a relative of them, the Watsonias, that is a different matter. Those I would if I could!
