Twitter2 of 12 Great Things I Found at Raleigh
By Lorraine • Oct 1st, 2009 • Category: Favourite Plants, Plants
At the 2009 Garden Writers Symposium in Raleigh North Carolina, I fell in love with…
2. Euphorbia ‘Ascot Rainbow’
Wandering deep within the display gardens at Plant Delights, I lost my heart to Euphorbia ‘Ascot Rainbow’. I stopped myself from sighing and drooling over this gem of a plant only long enough to whip out my camera to capture my heart’s delight forever (thank gawd the batteries held out…). Later, back at the convention centre, while coifing wine at a cocktail party, I met Susan Martin of Walters Gardens who told me this is one of the top new plants for Spring 2010, so watch for it at a nursery near you!

Is it hardy for us northerners, or must we treat it like an annual (sniff)?
Hi Kathy,
Believe it or not, it’s hardy to USDA Zone 5, which is roughly equivalent to Zone 6 here in Canada. So if you’re in the Golden Horseshoe region of Southern Ontario or in southern B.C., it should be fine for you. Susan cautions that as with any euphorbia, the trick in overwintering it (and she’s been successful in Michigan which gets just as cold as we do), is to give it good drainage. It hates wet feet, especially during spring runoffs. I’m certainly going to give it a try!
Cheers,
Lorraine
