Two unidentified plants
I'm doing more pictures, for the website, and so far there's two plants that I can't identify.
Here's the pics:
1) A yellow shrub, with largish trefoil leaf, and yellow big flowerspikes. It's something between a laburnum (but it's not hanging) and a butterfly bush (but it's yellow, and has those trefoil leaves...)
Pic: Yellow flower and leaf.
2) A magnolia-like large flower, and an equally large flowerbud. If they were leafless I'd label them Magnolia sp. and be done with it; as is, they have way too much leaf for magnolias in flower, so what are they?
I'm not quite sure that these two are of the same species. I expect they're in the same genus, though. They were growing rather close to each other, in Kew Gardens, in London, in early June.
