Just sent you and email about trading. Forgot to sign my name.

6A is really pushing it for the species (regardless of the cultivar). There are a few other varieties that I have seen listed as super cold resistant ('Pocono' and '24 below'), though I don't actually believe there is one to survive 24 below. All I know, is that around me, the most common varieties sold are Edith Bogues (originally patented from a NJ tree with Florida heritage) and Victorias (out of the Pacific Northwest). And yes, I see a difference in the degree of burning from other cultivars. Last two winter here were also bad. I get virtually no damage to the EB's or my two Victorias. Both cultivars are attractive and robust. New foliage on the Victoria has a reddish tinge to it (like a Rubber Plant). Cold is one factor to consider, there is also wet snow/ice load tolerance (which these two also definitely have).

Thanks so much for the help! I'm wondering if the problem could be aphids but, would aphids just go away by themselves. They aren't on any of the leaves currently. Anytime I've ever seen aphid infestation it's not something that goes away by itself. The awesome guy that does the lawn does use fertilizer and weed control but I don't think it could get up on the leaves and no other plants near the lawn have this problem. I'm glad to hear it doesn't look like major damage. The lilac is been there probably about 4 or 5 years old. I bought it as a small $25 bush at Lowe's .... Two years ago it almost died. I thought it was just powdery mildew but it could've been a combination aphids also. It's on the east side of the house where it gets full sun until about noon. Thanks again for everyone's help!!

Euonymus fortunei 'Coloratus' - Plant Finder '' Wintercreeper (Euonymus fortunei) has been identified by a task force of the Missouri Botanical Garden as one of the top twenty plants known to be spreading into native plant areas and crowding out native species in our region. Wintercreeper spreads both vegetatively and by animal and water dispersed seeds. Because of its known invasive tendencies and difficult to control dispersal mechanisms naturalists recommend against planting this plant.'' '''Garden Uses Where not deemed invasive it can be a versatile ground cover for sunny or shady areas in the landscape. Also effective as an edger along paths or sidewalks, as a slope cover where it can also provide erosion control, as a foundation planting. If used as an ivy-like climbing vine for covering walls, chimneys or fences, it more easily flowers and sets seeds that can increase its invasive spread.''
