Garden Flowering Log - July 2010

As you would expect flowering is slowing down in terms of the number of new species, but many of these summer perennials flower over a considerable period providing long displays. July has had a lot of hot and steamy weather, more than usual, and the trend has carried on into August, sadly. This isn't just summer weather, but really oppressive heat and humidity, the kind that melts your sneakers into the blacktop, the kind that is only pierced by the shrill calling of cicadas, the kind that tropical plants love, but that cook plants from cooler climates. For this reason a small conifer, Siberian cypress (Microbiota decussata), while hardy to zone 2, it suffers in this kind of summer heat. But plants at the northern end of their ranges, like the Magnolia virginia, seem quite happy. Having missed the last bit of July and the first bit of August, one or two flowering events might be mis-logged, but those things happen. For absolute certain another 19 species flowered in July bringing the year's plant flowering total to 252. Mrs. Phactor thought we might hit 300, but that seems a bit high. Her perennial bed is big, and you count on them for summer color, but there's also considerable redundancy. So far the champion in terms of longevity remains the Sinocalycanthus, which is still in flower having started on May 1.
