Fall Plant Sale at Bellevue Botanical Gardens
10 am to 1 pm
Fall is the perfect time to plant! Buy plants from a select group of local small nurseries and specialty growers who sell amazing perennials, shrubs, ferns, grasses and more.
This is a Farmer's Market style plant sale where you purchase plants directly from each seller - bring your own small wagon/cart.
The plant sale features plants from local growers including:
Celestial Dream Gardens, Fancy Fronds, Lee Farm & Nursery, The Lim Garden, A Plethora of Primula, Botanica, Blue Frog Nursery, Wanderlust Nursery, Wild Sprout Nursery and Earth Grown Creations.
The PARKING lot is often full - but additional parking is not far away - down Main Street at Wilburton Park.
