Gardeners' Notes:

These little gems are a gardener's dream. I've grown these in past years and they have never let me down. They're cheap to buy, easy to get established, have low water needs, and give a profusion of colour. Mine happily bloomed from early summer until the first frost. I got a pleasant surprise the next year when I discovered they had self-seeded, and gave me a bunch of new flowering plants!

These bloomed continuously this summer in a container on the deck railing where they rec'd quite a bit of intense sun. They add a nice pop of color and are very undemanding; I look forward to planting them again next year.
Oddly, just this past week a squirrel ate every single bud right off, even though they hadn't bothered them all summer. Who can get inside the mind of a squirrel?! ;)

These wonderfull little plants are perfect for hanging baskets, containers or a sunny bed. They are so bright and cheerful that they grab attention. They will tolerate poor dry soil but appreciate better conditions. The only fault is they want to close by 2pm but they are otherwise so special that they can be forgiven.
