Acca sellowiana zone 7A/B

[amh]

Looks like Its gonna be really cold in Texas this weekend and every model shows I'll  have temperatures at 11F or lower for 20 combined hours. Anyone in zone 7 have any experience with growing Acca sellowiana in the ground? My plants have experienced 8F in past, but for a few hours.

Will they survive?

I've had one in the ground here in 7b for the past 40 years. Some years it froze to the ground but always comes back. Mulch it heavily to insulate the soil against freezing too deeply.

Thanks, mine have experienced upper 7b before without any problems, but I'm on the warm side of 8a, and I have everything mulched already.

Have you ever had strict defoliation?

It's seen low single digits a few times, and has experienced anything from partial to full defoliation, to complete die back. There is probably a little genetic variation in cold hardiness especially if they are seed grown. There's a large one in the Raulston Arboretum in Raleigh that's named 'NCSU Hardy' that has proven reliable there. It is about 8' to 10' tall and wide, at least the the last time I saw it.

The website only gives it an 8b rating for some odd reason, but Raleigh is 7b and it grows fine there.

Thanks.

Most nurseries rate them as good to 5F.

Some plants have leaves that are purple/black, but no defoliation.

I'll clone the healthiest.

All plants have defoliated in areas that were above the snow, but most should survive.
