If so, trim damaged tops down to this material. Perhaps we will get some sunny days to encourage growth as well as blooms on other cool-season annuals. But we can put bedding plants in the garden now, and they will grow, then flower until the heat takes them out. Too much nitrogen will likely generate an abundance of those pretty, round leaves at the expense of blooms. The flowers are red, pink, orange and yellow to creamy white, and they attract butterflies and hummingbirds.
Nasturtiums are members of the caper family and are edible.
If you are going to eat any part of the nasturtium, do not spray or dust it with insecticides. Cut the blooms and leaves early in the morning when they are high in water content. Wash the petals and leaves in lukewarm water, and dry them with paper towels as you would salad greens. I have a large flower pot on the side of my garage door that gets afternoon sun. Some roots may stick out of the drainage holes.
