Hello Ward,
You are always filled with wonderful insight, stuff I never knew. I certainly don't believe the blooms from year to year will be exactly the same, just relatively close...say within a week or there about...
The weather surely plays a huge factor. It's just nice to know for those of us that are still new to gardening. For me, it's only my 2nd year. It's nice to start to recognize the stages/times of various plant bloom times...beginning and ending of each. Most though will last til the 1st frost toward Fall, but I'm still learning many we have in our gardens only bloom til mid-Summer...like Shasta 'Crazy Daisy'. I'll also be planting about 45-50 different Irises this year around late July in a brand new garden. About 2/5 will be Irises, 2/5 will be Butterfly host plants, and about 1/5 will have more Hummingbird plants. The Irises I know will only bloom until about mid June...except for the few that are re-bloomers.
It will be nice to see a new variety of plants in our garden other than mainly Agastaches, Salvias, Butterfly Bushes and Honeysuckles.
I'm also planting 4 new Daylilies too...
