Gardeners' Notes:

I started this annual, along with the 'red ensign', from seeds and was initially thrilled because the germination rate was great and the seedlings were strong. As they grew I found that aphids love this plant! I was able to controll the aphids by watering with a strong shower attachment and by the end of the summer they were cascading beautifully from our hanging porch baskets. I would try them again next year.

These some up quickly when seed is sown where you want them to grow. If you don't thin seedlings, you'll wind up with a gorgeous low mound of constantly blooming plants. There is no need to deadhead, and they require only modest watering since the leaves and blooms act as a built-in mulch. Groundhogs love them, however, and once the mound is decimated, the plants never regain their former beauty.
