This is a cross-post from the New England Gardening Forum. I'm a Zone 7(a). But, for the past 3 winters I have only recorded 2-3 nights that dropped below a Zone 8.

To this point, I've planted only to Zone 6 but I've decided to push my zone limits a bit this year. After much consideration I've decided on Calla Lilies & Agapanthus Headbourne Hybrids.

I'm thinking a southwest exposure & up against the foundation. I'll toss a good blanket of mulch over them in the fall.

Anybody growing either of these in Zone 7? Also, would you buy potted plants now or wait & plant bulbs/tubers in the fall?

Thanks for help & suggestions.
