Haven't seen this one before Potemup, it's probably a cultivar with one of the parents being f.denticulata, the botanical garden didn't give you the name of the other parent plant, did they?, or did they say it was a seedling from f.denticulata, as seeds very rarely come true to the parent plant - Kath:)

very nice flowers!

The petals are yellow...intresting! I want it, would they do it in the U.K.
You do know that that fuchsia is gall mite resistant.

There is an excellent article on Fuchsia and Fuchsia mite in the July/August/September 2006 Pacific Horticulture by Pamela Pierce. Here is a portion "Work with Fuchia splendens has created such hybrids as 'Strybing's Peach' with a peach tube, green-tipped sepals and pale yellow petals. This has an irregular growth habit and such heavy flowering that its vigor is reduced; however, it is quite rare to have any yellow on a fuchisa blossom. In 1940, San Francisco horticulturist Victor Reiter introduced Fuchsia 'Fanfare', one or both parents of which would now be called F. denticulata ..."
I got my plant at Strybing and it was labeled as denticulata. I try to keep it in check at about 6', but it really wants to get much larger. The tallest I have had any shot was about 12'. It is very vigorous and seems to start easily from cuttings. It is a bit ungainly. I am trying to keep one as a standard, but I am not being attentive enough to be very successful. It needs very regular pruning.

Here is a link that might be useful: Pacific Horticulture

The parents of this F1 hybrid developed at San Francisco Botanical Gardens (formerly Strybing Arboretum) are F. splendens and F. fulgens, not F. denticulata, which is in another section of the genus. Parents species are the same as Fuchsia 'Space Shuttle', though the accessions of parents were different.
