Seventy-five years ago, the Wilton Garden Club\u2019s first plant sale was on the lawn of Old Town Hall. All these years later, the sale has grown to be one of the largest in the region and spreads across the Wilton Town Green. Thousands of plants will be for sale Friday and Saturday, just in time for Mother\u2019s Day and spring planting. Sale hours are noon to 6 on May 9, and 9 to noon on May 10. New this year will be terrariums, dish gardens of succulents and tillandsia, which are air plants. There will also be more than 60 colorful baskets, troughs and patio pots, in addition to a wide selection of perennials, annuals, herbs, tomatoes and other vegetables, shrubs and trees. There will also be a garden tag sale. In showing off the baskets at the garden club\u2019s greenhouse last week, Melinda Wolcott said that \u201ctwo-thirds of the plants, like the coleus, have been grown in the greenhouse.\u201d The coleus plants were particularly successful this year, being grown from seed or cuttings. The caladiums are also \u201cgreat\u201d this year, Ms. Wolcott said, having been grown from tubers that were kept over the winter. Shoppers will also find giant alocasias and even a huge dwarf banana. The tiny succulent dish gardens are great for bathrooms, since they enjoy the humidity and tolerate low light, and the tillandsia will be mounted on bark or in glass containers. The weather this winter and spring has posed significant challenges for club members. An oil truck missed a delivery and so the greenhouse oil tank ran dry, resulting in no heat in January. Many plants died and the club had to regroup, growing new ones from seed. It wasn\u2019t a total disaster, Ms. Wolcott said, explaining, \u201cthe freeze gave us the chance to cull and cultivate.\u201d A disaster of opposite proportions happened more recently when the greenhouse ventilation system broke down. Members arrived to find the indoor temperature 138 degrees. The damage, fortunately, was not significant. However, the lingering winter weather has delayed the growing season by at least three weeks, club member Suzanne Knutson said. Many plants, particularly perennials, are dug from members\u2019 gardens. As a result of the lingering cold temperatures, club members were digging perennials for the sale in their winter jackets and gloves. \u201cPeople come to the plant sale for different reasons,\u201d said Ms. Knutson, co-chair of the plant sale. \u201cKids come for the tiny baskets, and some come for the begonias.\u201d Still others come for the tomato plants from Offinger Farm and at the same time fulfill the rest of their herb needs. \u201cThen there are the rock garden people. Everyone in Wilton has rocks,\u201d she said. Some come for their annuals and perennials, some for grasses and groundcovers. \u201cWe need to have everything,\u201d Ms. Knutson said. Spring also brings out the new homeowners, and club president Nan Merolla said, \u201cWe have gardening consultants at the sale. If you need help, we have master gardeners who can walk around with you.\u201d The sale also offers plants known as \u201cmembers\u2019 choice.\u201d \u201cThese plants are workhorses,\u201d Ms. Knutson said. \u201cThey\u2019re great plants, they\u2019re idiot-proof. They are long-blooming and die gracefully.\u201d Many are perennials and ornamental grasses. Some are award winners and some, she said, \u201care just really good secrets.\u201d Pinky winky hydrangea (Hydrangea paniculata) and lady\u2019s mantle (Alchemilla mollis) are two. The lady\u2019s mantle has a leaf similar to a geranium\u2019s and a chartreuse flower. It grows in part shade or full sun. The hydrangea is drought-tolerant, grows in part to full sun, and has pink blooms no matter the soil pH. \u201cThe reason we care so much that this is a success is that it funds all our activities,\u201d Ms. Knutson said. The club cares for a number of spots around town and pays for plants and garden materials. They include the Veterans Memorial Green, Horseshoe Pond, the post office garden, the garden at the intersection of Route 7 and Route 33, and the memorial across the street from the Stop & Shop plaza, as well as the large pots at town hall.
