I wonder if many people grow these: I have had them recommended by a friend who
has grown them in the past. (He could not remember where he got seeds from)

I have found a company that sell them on Amazon - but I wonder why, as far as I
can see, none of the major seeds companies seem to sell them?

I have also seem them on ebay: but I would not be surprised if someone has
grown them and then harvested the seeds - which of course would mean that they
are not F1.


I wonder why the larger seed companies do not sell them?


Any sources recommended?
