Barbara Eisenstein at Weeding Wild Suburbia has a timely post about Summer Color (that’s not brown) and she includes a downloadable list of plants which have summer and fall color. Her photos of Goldenrod, Solidago californica, and Fragrant Evening Primrose, Oenothera cespitosa, are beautiful. The Fragrant Evening Primrose is one of my favorite plants. There are sometimes a few at the RSABG Fall sale, and they often look so bedraggled in their plastic pots that no one picks them up and I have bought the whole lot of 3 or 5.
I’d like to add to her list of summer and fall bloomers by mentioning some of the plants that almost always have some flowers, whatever the season, such as Island Bush Poppy, Dendromecon harfordii, Lilac Verbena, Verbena lilacina, Apricot Mallow, Sphaeralcea ambigua, Desert Marigold, Baileya multiradiata, and San Diego Sunflower, Bahiopsis laciniata (formerly Viguera laciniata).
