I've scoured the net and have only found info on when perenials should be planted by seed in my zone (6). I want to plant Echinacea, Hardy Hibiscus and Purple Sage now even if they won't flower this year. I'm hoping they will harden off enough and store enough food before it gets cold and they go into dormancy. I probably have 3 months before if starts getting colder. Any advice?

Hello Elbowrust and welcome !
I have Echinacea too and I let the blooms go to seed and they self-sow in July/August. My new little plants do fine through winter and most bloom the second year. So what do you have to loose? Give it a try.

Thanks for the reply and welcome katesflowers! So your Echinacea seedlings survive a Michigan winte? Do they die back or just stay as they are? I have one pot already germinated and just getting their first true leaves.

Yes, they die back to the soil line, I trim them down to the ground. I know they are hardy to -33 degrees fahrenheit, which is as cold as it ever got here.
Can you just plant your seedlings in the ground where you want them? They certainly would not need to be in a pot, and I would think they would weather the winter better in the ground. OK to do that now, if that is what you decide to do.
good luck!

We're house hunting and I'm trying to build up plant stock for the new house so unfortunately they have to be in pots for now. I have most of my plants in pots still and they survived this last winter although it was mild in comparison. Thank you for your awesome advice!

Echinaceas die back in zone 7 only to reappear in spring. They self sow readily. I've got some of this spring's seedlings in pots for the first time. I'm hoping to move them to a new hillside wildflower setting. I'm trying to make sure that the new wildflowers do not include sedge grass before setting out my little plants. I generally try to avoid chemicals, but research has shown me that this may be necessary.

Elbow-thank you for the acorn!

I moved 28 years ago. After the move experience, my new motto: "Bury me here - I'm not moving again" !
I couldn't leave my plant buddies behind, so I created a 2 acre holding area at our new home and healed all my plant there until proper planting could take place.

Elbowrust,
I kept my echinacea it's first 2 years in a tin pot. I realize that we are in different zones, but we get cold and snow here as well. The second year we had 7 snows and it survived all of them beautifully. I'd sow them.

One thing I have discovered is that the less hybridized your plants are, the more likely they are to survive. My original echinaceas have reseeded for 20 years and have been passed on to many friends. Several newer varieties sometimes don't seem to survive the first winter.

Of course, the same seems to be true of many kinds of plants. Bearded irises are sun lovers. However, when we bought our home 20 years ago, I discovered that some old-fashioned white irises had chosen to bloom at the foot of an oak tree halfway down the mountain. It is too dangerous for me to climb down to move or divide them. Every year they remind me that nature is tenacious.
