TomeKK...intermedia yes, but has been so long ago, couldn't say how long it took. I've since grafted better varieties of brasiliensis onto it. The other brasiliensis were also grafts onto big livingstonei trees that I cut down. Most stuff will take longer than say someone growing the same thing in Hawaii or Miami, Fl. Just don't be discouraged by this either.
Agreed, tropical fruit growers like us who live in temperate areas just have to realize that we are probably not going to get fruit in the same time frame as people growing that same fruit in Hawaii, Florida, or other places where those species belong. We do not have the growing season. I just look at it as a challenge. Plus, I enjoy tending to my plants in January when nothing is green outside. My fruit plants may not have fruit yet (for the most part) but at least they have some green leaves to liven up the winter.
Congratulations on the Madrono. Hopefully, it will be followed by many more.
Also, thanks for all the stuff you have posted on your website over the years. It has been quite helpful to me, as a temperate region grower who has only gotten into tropical fruits in the past few years.
