Todd, somehow I missed this. I'm glad I looked back thru and caught it. I've been looking at the Northern Lights series for a while because of the great colors. Nice to know they are hardy and grow well for others. Guess I should take the plunge.
I planted the Lemon Lights ( or could be Hi-Lights, lost the tag) about 2005 and have moved it probably four times. It stayed pretty small as a result until I planted in on a slightly sloping southern facing hillock. It went nuts and quickly grew to about 3+ feet and full of wonderfully fragrant yellow flowers. Anchorage generally never goes below -25, and lately has run more like +15 to -15. I also have two rhododendrons that also do very well. Last year I caged them and wrapped them in burlap because in the spring they would have shriveled brown leaves on much of the plant. I had heard that with the rhody they become dessicated over our fairly long winter. Sure enough come spring when I uncovered it, still surrounded by over a foot of snow, it looked as green and sharp as in mid summer. I also covered the azalea but the cage failed and collapsed slightly. Even then, the well protected parts seemed to to better. They survive without the cage but are much healthier and take off earlier with winter protection from sun and wind. I now have a pink, mandarin and yellow azalea. I ordered a white, waited two summers for buds and ended up with a pink. Thanks Bluestone!! NOT.
