The Amelanchier Lamarkii is, I think, my favourite in the garden. Although usually grown as a tree I train it as a large shrub so that all the blossom in spring and the green leaves afterwards are at eye level. Also the red berries later in the year are sufficiently low that I can see them and enough off the ground that the cats can't get at the birds while they are feasting.

I took this picture four days ago. Now the patio is covered with blossom as it is going over. At least I'm not having a repeat of the spring when strong winds stripped off all the blossom immediately it appeared so we had virtually no berries later.
