It normally blooms in mid-season. That may be past for you. I know when I was in Oregon and Washington, their plants were about 1 month behind in blooming, very unusual.

If the buds are still green, there is ample moisture in the soil but it is not soggy, then you should be seeing some flowers soon.

The amount of sun is important in setting buds during mid summer. But once the buds are set, it really has little to do with blooming.

My limited experience with Cherry Cheesecake and the similar Eruption - both Hachmann hybrids - is that they frequently produce new leaves before or at the same time the flower buds begin to open. This does tend to somewhat obscure the flowers themselves.

Too soon to tell for sure yet, but I think the flower buds of both these hybrids are a good deal less hardy than the plant itself. If you had a colder than normal Z5 winter last year, the buds may have been killed. As rhodyman wrote, however, if they still look green and healthy they should eventually open.

This has been a very odd bloom season for me as well. Deep snow all winter, tremendous bud set last summer and colder than usual temperatures. Some varieties bloomed at the normal time, others extremely late. Roslyn, Polarnacht, Jonathan Shaw are just opening now, for example.

Here is what Rarefind Nursery says about Cherry Cheesecake:

Hybridized/Introduced By: Briggs Nursery

Parentage: (Tetraploid form of Hachmann's Charmant)

Briggs Nursery took 'Hachmann's Charmant', doubled the chromosomes and it now appears to be a different and better plant. We had stopped growing the original 'Charmant' because it made up into a lanky plant, even though the flower was sensational. This new version is compact, with very deep green leaves nd the same sensational flower. And yes, it does remind you of Cherry Cheesecake.

Thanks rhodyman and mainegrower. The buds are still very green and round. I am in Ontario, Canada. We had a very cold winer with lots of snow. A totally lousy spring with lots of rain and wicked weather. My minnentonka, purple passion bloomed and quickly faded under extreme heat.

I will wait and see if they will bloom. Have a great weekend.
