ellen I have to say, nasturtiums are a personal favorite with their circular lily pad leaves. This year’s blooms are almost neon! Best grown by seed, they like full sun and average dry soil; they can clump, trail, or vine dependent on the variety you plant; and they’re edible with a great peppery taste. If you’ve got a black aphid problem, putting a few nasturtium in the garden will attract the pests. You can pull out the plant, aphids and all, and dispose of them both. 
Nasturtium Vinegar
- 1 cup leaves and flowers
- 1 pint white wine vinegar
Make sure the greens/flowers are completely covered and let sit for 3 weeks. Add chives and peppercorns for a more robust flavor.
