We have had three weeks of hot and sunny weather in Alberta. The trial garden at the Calgary Zoo was actually too wet for a while due to some irrigation problems. The plants, and the weeds, loved the combination of hot sun and plenty of water. Thanks to the wonderful help of our many volunteers, the weeds are now almost under control.  With the fantastic weather there are many perennials in full bloom in the gardens.

There are four Trophytaker daylilies currently in the trials, all planted in 2008. Hemerocallis ‘Apricot Sparkles’ is a deep apricot-yellow lily-shaped daylily. It is reported to be everblooming, from May to frost. This year it began blooming in mid-summer, but this is only its second year in the garden and next year it may have a longer bloom period.

Hemerocallis ‘Strawberry Candy’ is another Trophytaker daylily sporting coral pink flowers with a strawberry-red eye.  It is a repeat bloomer, flowering from mid to late summer.

The other two Trophytaker daylilies in the trials are H. ‘Rooten Tooten Red’ (which is blooming, but I haven’t caught it in time to take a good picture) and H. ‘Final Touch’, which is just about to bloom. I will try to get a good picture of each in the next few days.  

 Hemerocallis ‘First Knight’, is in the final year of the trials and will graduate this year with flying colours. It  has large creamy yellow blooms with ruffled gold edges.

Our three Buddleia davidii ‘Black Knight’, which were planted last year, are in bloom now. The flowers of this cultivar of butterfly bush are a gorgeous dark purple with an orange centre. These are zone 5 plants, so it was a pleasant surprise that all three plants survived the winter, and an even greater surprise that they have bloomed.

Remember the new shasta daisy, Leucanthemum ‘Broadway Lights’ I talked about a couple of weeks ago? The flower that was such a pretty pale yellow did indeed fade to white. The same plant now has several flowers in various shades from yellow to vanilla to white. Each individual flower appears to be very long-lived.

 Oenothera ‘Lemon Drop’ is a new introduction from Proven Winners. The plants started off a bit straggly-looking, but they have filled in nicely and have been blooming cheerfully for most of the summer. This is zone 5 plant as well, but I am hoping for another pleasant surprise!

This week I will be visiting the other two Alberta Perennial Trial sites in Olds and Edmonton. I’ll be sure to take lots of pictures!
