So many great questions were asked during the Question and Answer period, there wasn't time to address them all live. We have since compiled them into three groups by topic (plants, insects & birds, and management) and asked our in house experts to share their knowledge and suggestions:
Community Events
Partridge Pea Seeds April 19-May 2, 2021
Many of you picked up seed Partridge Pea seed packets to try out in your home gardens.
Partridge Pea (Chamaecrista fasciculata) is an annual plant native to most of the eastern U.S. It grows to about 2' high, with an abundance of cheery yellow flowers in the latter half of the summer that are magnets for bees. Many native plant gardeners like it as a “bridge” plant, helping suppress weeds and fill in spaces between perennials until the latter become well established. For more information and planting instructions, click here.
Our First Native Plant Sale April-May, 2021
The Native Plant Kits we sold in collaboration with the Lexington Conservation Department were very popular. All 1200 plants were sold and planted in gardens throughout Lexington and nearby towns! We offered four species, chosen for bloom time and attractiveness to pollinators: Zizia aurea (Golden Alexanders), Monarda fistulosa (wild bergamot), Pycnanthemum tenuifolium (narrow-leaved mountain-mint), and Solidago caesia (blue-stemmed goldenrod). Grown at a certified organic native perennial farm in New Hampshire, they arrived as robust, healthy young plants.
Thank you to Amber Carr, Lexington's Conservation Coordinator, for her leadership; the Conservation Commission, for fronting the funds to order the plants; and to DPW staff for their vital logistical support. We hope to hold another sale next spring. For more ideas on sourcing native plants for your garden, take a look at our Where to Buy Plants page.

Our First Open Gardens Day September 2022
Approximately 100 people visited the 12 gardens that participated in our first Open Gardens Day. The gardens ranged from professionally designed landscapes to do-it-yourself backyards, from gardens many years in the making to ones recently begun. A huge thank you to the homeowners and garden designers of the twelve participating gardens for opening your yards to the public, providing so much useful information, and answering our endless questions.
We're thinking of doing it again, perhaps next June when gardens will be showing off a different palate.
If you were inspired by your visits to these gardens, here are a few resources you may find helpful this fall:

Community Conversation About Lawns October 2022
Homeowners are rethinking their lawns. Is a beautiful green carpet of grass worth the time, money, and environmental impact it entails? A monoculture of non-native turf grasses – the centerpiece of suburban landscapes for decades – offers little benefit to wildlife, and the water, fertilizers, and pesticides applied to lawns come with a significant environmental cost. Forty Lexington homeowners came together to explore options, ranging from more environmentally friendly methods of tending traditional lawns, to converting them to native ground covers, or to ripping them up and putting in more complex, native plant landscapes.
Our Third Native Plant Sale March-May, 2023
All the native plants we made available in collaboration with the Lexington Conservation Department sold out well ahead of the May 13 pick up date! We offered both sun kits (50 kits sold, containing 3 plants each of pussytoes, rose milkweed, scarlet bee balm, and purple coneflower) and shade kits (65 kits sold, containing 3 plants each of wild columbine, Jacob's ladder, hairy beardtongue, and wild geranium), and new this year a la carte offerings: 30 each sold of common wood sedge and St. John's Wort. Grown at a certified organic native perennial farm in New Hampshire, they arrived as robust, healthy young plants, and are now being planted across Lexington..
In addition, Holly Samuels, who oversees the Lexington's Native Plant Nursery, brought numerous young plants for sale including: Echinacea pallida (pale coneflower), Penstemon hirsutus (northeastern beardtongue), Allium cernuum (nodding onion), and Pycnanthemum incanum (hoary mountain mint). Most of these sold out as well!
A great many native plants are being added planted througout Lexington.
Thank you to Amber Carr, Lexington's Conservation Coordinator, for her leadership; the Conservation Commission, for fronting funds; the Recreation Department, for facilitating the online sales; and to DPW staff for their logistical support.

Our Second Open Gardens Day September 2022
We got lucky with the weather in this otherwise rainy year. On a beautiful Saturday, 14 homeowners and garden designers made private home gardens available to visit and ask questions. The gardens ranged from professionally designed landscapes to do-it-yourself backyards, from gardens many years in the making to ones recently begun. A huge thank you to those who hosted this year's many enthusiastic and curious visitors.
A reminder: You can visit our two demonstration gardens: the Bikeway Pollinator Meadow and the Hastings Park Garden, where you will find plant labels and other informative signage, on any day of the year.
