The alliums are blooming right now. My kids love these plants to use as magic wands! If you like them, make a mental note to plant some bulbs this fall. 'Purple Sensation' is a variety that is particularly easy to grow in Calgary - even though they come back reliably, I always plant a few more every year.
Clockwise from the top you can see it paired with: golden hops in the Butterfly Potager Garden; and saponaria (soapwort), bearded iris, late yellow tulips, blue oat grass, iceland poppies in the Adventure Garden.
