I'm in a warmer zone and it overwintered for me, a pleasant surprise. Bought it on the clearance rack at Lowe's for $1 last Summer, now I wish I had bought more. According to the Blooms of Bressingham site, it's a tender perennial. I've given up on overwintering it's cousin, 'Limerock Ruby', I treat it as an annual.

The newest one I have is also 'Autumn Blush'. I have three, though one came back much smaller than the other two, they all survived the wet winter we had here. I really like the pale yellow of 'Snowberry', but it is not hardy to my zone. I'm hoping they will eventually come out with a red/burgandy one that is hardy to my zone too. I've grown the annual red one 'Mahogany Midget', but the plants were too small to be seen from any distance. I guess if you planted a mass of them, they might make an impact. Bonnie

My experience with Russian Sage was a failure. I started a bunch of plants from seed. I had good germination and planted the seedlings in the garden to start. My garden tends to be very gravelly. They wintered okay. I donâÂÂt remember how long I left them there, but when I attempted to move them about the yard I eventually lost them all. They didnâÂÂt die outright, but took forever to come up in the spring and never reached their potential. I gave up on them. Then I tried the same thing with agastache. Seedlings actually wintered in their little cell packs. I thought that I was going to regret planting this hardy plant in my perennial bed. It was lovely but seemed so hardy. I thought it would seed all over, since it was so easy from seed. None are left! But wait, I think IâÂÂve found something that looks like it in a forgotten corner! I really think it may not be so much a hardiness issue though. If you have the right conditions for the plant, I mean the correct PH and soil type, etc. maybe youâÂÂll have success. However, IâÂÂve had the same experience of having a plant grow successfully for years then upon losing it for some reason or other, having every replacement die immediately or the first winter. Two that come to mind are monarda and sedum âÂÂAutumn JoyâÂÂ. Some of your disappointments are growing successfully in my yard, Donna. I have several clumps of veronicastrum or culverâÂÂs root doing quite well. I started them from seed. Not sure I like them yet. This should be the year to tell. Sea holly thrives in my gravelly garden. I know someone who has turtlehead growing naturally out at the lake here. But the others you mentioned, coreopsis, helenium, tiarella, IâÂÂve tried and failed with. I can add echinacia to that list. I've always wondered about that theory about single specimens being hardier than the rest. I have some plants rated zone 4 growing happily in my yard. Is it a fluke or were they just rated wrong to start with. I guess thatâÂÂs part of what makes gardening such a great hobby though. ThereâÂÂs always surprises to balance out the disappointments.

he owns a farm in Hawaii and just brought that 508 cuttings he probably few dozen different species and some really rare ones the name of the place is Love tropicals get online or on Facebook.he does go up to Walnut Creek every once in awhile to some farmers markets.or you can make an appointment to stop by his place it is well worth the time I have 2 inflos on one of my plants and 3 on the other give them time
