This is an easy one. Simply take cuttings toward the end of the season (before first frost). Put them in a glass of water and watch them sprout roots. Be sure to pinch off any flower heads that might form. And don't leave them near an open window. When temps drop below freezing, they'll succumb.

Once any chance of frost has passed, you can plant your cuttings outside. They'll do very well. Repeat as often as you like.

Joanna, do you leave them in water all winter? or pot them up after they sprout some roots?

I've done both and they both work well. I'm on my third season now!

Sometimes, I bring the whole plants in to winter over.

Yes! Those would be in pots? Or do you dig them up? Mine are in the ground. If find they do better as cuttings, but I'm in a super-cold winter climate zone. Especially now!

LOL, Joanna -- I think Caroline has a pretty good grasp of "winter climate" Big Grin
