Its the time of the year that you see chrysanthemums popping up all over gardens in the Northeast. In some zones, all mums are hardy perennials. In Pittsburgh you will see two types and hardy ones will be marked as winter hardy in nurseries.
With global warming though our winters are becoming milder and even non hardy mums may winter over. So we will leave ours in the ground until spring and see which ones survive. The colors are very vibrant for weeks.
We always considered Gerbera daisies to be annuals. However the U.S. Department of Agriculture says the plant is hardy in zones 8 to 11. Although Pittsburgh is a Zone 6 we have had very mild winters due to global warning and our daisies now seem to be perennials. I hope it is another mild winter so I can see this flower again next summer.
Dahlias have always been one of my favorite summer flowers. They are perennial plants native to Mexico and related to sunflower, daisy, chrysanthemum, and zinnia. I always thought they were only one color but these are a beautiful multicolored variety.
Nothing means summer more to me than seeing sunflowers in bloom. Sunflowers are right up there with boston coolers, watermelon and ball games. These are Canadian sunflowers that I captured wile visiting the Jardin botanique de Montréal which is a wonderful place to visit while in Montréal. In addition to the many different gardens their is a large Insectarium which many people love. I will stick with the flowers. You can buy a print of this image at my gallery by clicking here.
