Interesting. I've had aphid issues at my current house. But they just stick to a few types of plants. Mostly my heliopsis and mums. They don't really seem to damage either, even when there are LOTS of them. One year they did harm my Honeysuckle. But I had ladybugs munching away so I did not do anything to treat for them.
I'm going to try the nasturtium. I'll keep an eye out for the aphids.
