For Michelle, whose garden encompasses eight acres in the heart of St. Louis County, gardening is all about sharing. Whether it is three cuttings of special mint passed on to a fellow gardener, dinner in a succulent-filled greenhouse for family and friends or an invitation to the general public to view the garden as part of last year’s Nature Conservancy tour, she firmly believes the historic garden, of which she now considers herself the caretaker, is meant to be enjoyed by others.
