What's Blooming in November:  A Call for Photos from Warm Climate GardenersWhat's Blooming in November: A Call for Photos from Warm Climate Gardeners
November 15, 2011

Here at Cottage-in-the-Meadow Gardens, our outdoor gardens are in their last-hurrah stage as frost creeps across the landscape. As you'll see, there are still a few hardy stragglers outdoors, but for the most part, our gardens have been put to bed for the coming winter. This time of year presents a perfect opportunity for gardeners in warmer climes to show us what's blooming in their gardens. Floridians, Californians, Aussies, Kiwis, gardeners anywhere in the Southern Hemisphere or the southern reaches of the Northern Hemisphere, show us your blossoms! I'll publish as many photos as time and space allow.

Direct seed or set out starts of sweet alyssum near plants that have been attacked by aphids in the past. Alyssum flowers attract hoverflies whose larva devour aphids. Another plus is that their blooms draw bees to pollinate early blooming fruit trees. They will reseed freely and make a beautiful groundcover every year.
A hardy annual, native to Southern Europe, but has naturalized throughout the United States.

The fragrance of this plant is honey-like and charming, especially when wafting on a summer breeze, but it is extremely vigorous and can easily overwhelm and smother smaller plants. I planted it because it is said to attract bees and hover flies, but the bees in my area ignore it in favor of more attractive nectar sources like basil, agastache and Russian sage. Occasionally I will see tiny sweat bees and common house flies on the blooms.
