Brown Roof; a Green Roof Update
Everything is dormant now, in the hills and prairies around Missoula, and in our native plant garden, too, save for some goldenrod (Solidago rigida, and S. canadensis), blanketflower (Gaillardia arristata), fleabane (Erigeron spp.) and hairy golden aster (Heterotheca villosa)
In my last update about the green roof on July 5, I said I'd water it once a week to get it established. I didn't. I guess that is one of the downsides of planting things on a roof is that they are easily overlooked. It is a little startling to look back to the first week of July and see how much the roof has changed- I'd forgotten it was so lush (see photo below). And that happens every year.
I think the plants are fine, though. If you look closely through the brown of the roof, a little life is showing itself.
Despite the temperatures in the mid 90's, the days are shorter, the nights longer, and and soon rubber rabbit brush (Ericameria nauseosa) will flower, and that takes us into fall.
