overwintering perennial salvia & agastache

oliveoyl3October 28, 2011

How you would overwinter autumn sages, Salvia greggii & Agastache 'Acapulco Orange'? How about treating the pots like like fuchsia baskets kept on the dry side & dormant in unheated building?

OR

Would you go ahead & transplant now? Location is in the rain shadow off Bush Point on Whidbey Island. I don't know the exact measurements, but this places has much less rain than the Seattle area and certainly my east King County location.

I had Salvia greggii live over in pots with no special treatment. Outside exposed to sun and rain.

I think if you treat them like a fuchsia basket you should be fine. I've been unsuccessful here in Olympia overwintering any salvias or agastaches in the ground. We get way more rain than Seattle but I think it's the cold that gets mine, they're in a raised bed with excellent drainage.

I'm also in Olympia and agree that most new world sages - the greggii/microphylla/x jamensis family, darcyi, chamaedryoides, etc. plus most Agastaches demand this treatment in the South Sound. I think it's the combination of 50 inches of rain, sudden and severe freezes without the opportunity to gradually harden off like last December, and the missing summer heat that they crave. Nurseries in California and the SW have exaggerated their hardiness but NC growers Tony Avant and Rich Dufresne have over-wintered many of these and have comparable or even lower winter lows.

There are exceptions such as guaranitica from South America, which is the #1 choice of the hummers, and a few others. In addition, many European, Middle Eastern and Asian sages are hardy here.

I confess to being a full-fledged salvia and fuchsia enthusiast. In the interest of promoting additional conversation now or later, here are most of the ones I'm growing now. These span the range of tropical to marginal to rock hardy. An asterisk indicates especially outstanding garden or container worthiness IMO. My x John Whittlesey, a cross of darcyi and microphylla, is absolutely incredible - I posted a pic of this one recently on the salvia forum. I planted it this year and do not expect it to survive in the ground. I have seeds of many of these. The 2 best autumn sages I have grown are Royal Bumble and Sierra San Antonio.

Hi Corrine, I lost my salvia guaranitica "Black & Blue" when I tried to overwinter it in the ground so this year I'm moving both it and my agastache aurantiaca "Apricot Sprite" into the cold frame for the winter. I hope they can survive there.
