Gorgeous!!! I'll hopefully be getting to Kew this week, so you've given me a target to beat
#3 for me (is that an Aloe?) I grow that sort of thing, but never thought to photograph the buds...d'oh! The composition and patterns are very eyecatching.
Btw, I can play snap on #2
It's a Camassia btw (probably cusickii or leichtlinii). They're quite exotic looking but actually quite easy to grow. I chucked half a dozen in last autumn and they've flowered magnificently!
