This will be an incredible weekend at the Arboretum. Rising temperatures (into the mid-80s F) will encourage sluggish Azaleas buds to open; Redbuds, Lilacs, and Viburnums continue to flower, Tree Peonies and some Iris a starting to bloom as are many many other plants.
There is a book sale in the Administration building featuring duplicate volumes from the Library. Saturday will be the main day for the FONA plant sale that also features books, gardening paraphernalia, a few textiles, some jewelry, and probably other things I have forgotten! Fern Valley, the Native Plant Collection, is open and beautiful; the native Azaleas are just beginning to bloom, Trillium grandiflorum carpets various areas, Stylophorum diphyllum, is abundant. The Azaleas collection that had been lagging a bit due to the cool spring will explode in response to this weekends forecast heat. I'm scheduled to water Sunday, but I'll be in Saturday too: its too good to miss!
