I have been trying to finish off my seed collection. But I am having horrible luck getting all the barrel cactus that I am missing. Every time I pollinate I end up with something totally different, as I have read it is not unusual. Is there, by chance, a gardener that could hook me up with the seeds I am missing. I am willing to pay for them. The ones I am missing are yellow and bright yellow barrel cactus and bright green barrel cactus. I would greatly appreciate any help. Thanks for reading
