I bought three types of lavender - English, Munster and Blue Mound - on a whim late last year, planted them, realized they were too damp there. The only dry sunny place I have to put them is in a barrel in the NW corner of the yard. I think they'd add color to an ugly spot near the trash cans - maybe with Purple Fountain Grass as an accent.
But: I'm wondering if anyone has had any luck overwintering perennial plants, above ground, in a half barrel. I'm afraid the roots would freeze and I'd loose them, 'cuz no way can I move that barrel after filling. Thought of bubble wrap, and old blankets - desperation. Can't put plants or pot in ground there due to concrete plate 6" under the ground.
I'm gonna add compost and spread Cosmos and portulacca seeds around, want the barrel in the corner. Please tell me it's possible, zone 5bCentralDenver. Thx
