What are your favorite perennial flowers?

so I hope to arrange things better this year.

It's nice to troubleshoot and make plans to fix it next growing season.

For instance, my common and swamp milkweeds were pretty the first time they bloomed in 2023, but got awkwardly large and messy last year. Their size also took away from the other plants in my small cottage garden setting. I made the decision to dig them up and transplant them into the woods, and I'm glad I did.
Culling plants you don't love can be quite enjoyable, in my humble opinion

After watching my perennial Fama Blue Scabiosa bloom through much of the winter in zone 7, this plant has earned the distinction of being my current favourite flowering perennial. Blue blossoms are so rare-- and these flowers not only have an unusual colour but an intricate, delicate form too. I highly recommend trying to grow this plant from seed. The first year not much happens as the plant is likely putting most of its energy into setting down strong roots-- but from year two onward it's spectacular.

My seeds were purchased from Swallowtail Seeds. Perennials from seed have to be really handled carefully when they are seedlings as they grow much, much slower than annual flowers-- so plan on having extra patience with them. Here is a link to a post showing what the flowers look like: https://www.theeasygarden.com/threads/branching-outs-seeds-and-sprouts.25079/page-47#post-439026

And clearly I'm not the only one who loves this flower:

And, they make spectacular additions to bouquets, @Branching Out !

More subdued is blue cornflower but, probably the best choice for the garden is the annual. The wild type may be available in your neighborhood if you want to forage for bouquet choices. Filling in some gaps in a perennial garden with larkspur is another annual add.

I see that @AriBriggs has changed the title of his thread ... and here I am again –– interfering with annual comments!
