Have you had any luck with Gaura? We're borderline zone 4/5 here and it never comes back the next spring, are you growing it as an annual? If you know a trick to overwinter I'd love to try, it's a beautiful flower.....Gaura is supposed to be a zone 6 and higher perennial, right? With those instructions you should be fine with milk jugs outside but I haven't tried it....

I still have all of my more tender perennials/annuals in milk jugs/2 liter soda bottles with the lids on but not taped, they seem to be doing fine but they're on the edge of a covered deck so they only get really sunny early morning and mid-late afternoon. Just need to make sure you don't fry them with too much sun/heat.

I had 1 of 3 Siskiyou Pink overwinter this year and it has come back perfect! The other 2 were coming back this year until we had another wet snow storm and It is slmost like they rotted? The one that made it was mulched with leaves and cedar...but it was in worst soil of the three?

I have lots of white gaura plants if anyone wants it.

Mori1 I will send you an email about the white Gaura plants.

I know I have some little seedlings that survive the lawn mower.
