Two Wilton gardens will be open to visitors on Sunday, Sept. 17, as part of The Garden Conservancy\u2019s Open Days program. Pixie Perennials and the Tom and Doreen Harris garden will be open from 10 to 4. Pixie Perennials is a terraced perennial garden on four acres that surrounds a 1740 home. A small rock garden leads to a fish pond. In late summer a stand of perovskia creates a blue backdrop for fall flowering perennials. Home-grown perennials and shrubs, plus garden ornaments and vintage watering cans will be for sale on the back patio and adjacent areas. Plus, a pop-up boutique in the barn will feature items for sale by local artisans, including: Ellen Hoverkamp \u2014 Photographic note cards, prints, scarves & book. \u00a0 Nod Hill Mosaics \u2014 Embellished gardening and kitchen aprons, mosaics.

Pixie Perennials is on Nod Hill road, 0.9 mile up from the intersection with Ridgefield Road. Visitors may park in the driveway or on Spruce Meadow and walk the short distance to the garden. The Harris garden, at 9 Shagbark Place, has been 22 years in the making. Complementing the owners\u2019 modern home, the garden was originally designed to provide cut flowers but has evolved to include structure provided by boxwoods and unusual trees. There is also a \u201cprairie vibe,\u201d according to designer Laura Tuttle Stabell, with a generous planting of grasses. This time of year visitors should find rudbeckia, a mix of sedums, dianthus, dahlias, grasses, and a variety of perennials including asters, monkshood, and bluebeard. Stabell will be on hand at the garden at 11 and 4. Admission to each garden is $7 for Garden Conservancy members and nonmembers without tickets purchased in advance.
