Indulge me while I post too many pictures of laburnum, but I love the stuff even if it is poisonous. I like other cascading flowers such as wisteria also.
This is the time of year for rhododendrons and azaleas. I especially like to see orange and yellow ones, which aren't quite as common in these parts.
A number of these mauve flowering bushes are at the gardens, all in pots. I still don't know what they are. Update: Butcharts' plant indentification centre tells me it is "Prostanthera rotundifolia" commonly known as Australian Mint Bush.
A few tulip beds remain but many have been replanted. The beds have a 'between seasons' look.
Just when I'd given up on seeing many blue poppies here they are! Best of all they're blooming along with the orange azaleas (I think) making for a lovely colour contrast.
Blue poppies are just starting to appear. Last year there weren't any by the beginning of the second week of May when we left town.
I have no idea what these small, bright yellow flowers are. Update: I'm told the miniature yellow flowers are "Hoop Petticoat Daffodils." Thanks, Mrs. H.
Glenn took this photo of a rhododendron.
I was surprised to see blue poppies still around. I think last year they were finished by now. 
I love columbines.
It was nice to see roses out too. Top: Double Delight. Middle: Rainbow Sorbet? Bottom: I don't know.
Our province's flower, the dogwood.
