As noted elsewhere today, we visited the UBC Botanical Garden, and only the early rhododendrons and a few magnolias were in bloom. I didn’t get any good rhodo shots, but with magnolias you can’t miss. If extreme densities of the colour pink bother you, please stay away; but these are some awfully great-looking flowers.
The first picture here should let you know that magnolia trees can get big; today’s the first day that I’ve managed to get anywhere trying to shoot magnolias at a distance.
I think that pretty well any of these would reward enlarging.
