Agave flowers in the UK used to be rare, with the amount of collections and time many growers have had their plants, they are getting more common every year. I know many people who have had not just one plant flower but several. Once flowering, the ultimate dream for many growers is to produce a hybrid. So It is no surprise that more agave hybrids are coming on the market all the time, some purposely produced, others lucky coincidences.
Once such event happened with a good friend. His a. obscura came into flower and he managed to get hold of some pollen from a. lophantha. I was offered some of the resulting seed, but not having much luck with seeds I waited until there were some young plants. They seems to fall into two groups, one with a well defined mid stripe, the other with darker spines.
The one on the right has nice dark teeth and for me is the nicer of the two forms. I prefer good teeth to central stripes and it has a more defined look:
I am sure the donor will be asking for regular updates to check he hasn't given away the best plants. Mind you he has a few spares, plus a few hundred seeds left.
