Thursday, June 6, 5:30 pm – 8:30 pm Eastern – New England Roses, Online

Our native New England roses have charming fragrant blossoms that attract a wide range of pollinators, while their spiny thickets provide important wildlife habitat. These hardy shrubs grow in a wide range of habitats and are great additions to flower gardens. Learn to identify Virginia rose (Rosa virginiana) pictured below, Carolina rose (R. carolina), swamp rose (R. palustris), bristly rose (R. acicularis), and shining rose (R. nitida), several non-native species, and the invasive multiflora rose (R. multiflora). Dubbed “the queen of flowers,” roses are perhaps the most recognizable of blooms. Several rose species are native to New England. Many more are introduced and naturalized and have become a familiar part of our landscape. Their beautiful scented blossoms are popular with pollinators, spiny thickets provide important habitat for wildlife, and hardy shrubs and ramblers are prized by gardeners. Learn to distinguish native species, common naturalized species, and the invasive multiflora rose, and become familiar with their habitats.This Native Plant Trust class takes place June 6 at 5:30 pm with instructor Neela de Zoysa, online.

Saturday, May 11, 10:00 am – 1:00 pm – Inland Pine Barrens

Glacial outwash creates an unusual inland sandplain habitat of pitch pine (Pinus rigida) and scrub oak (Quercus ilicifolia) amidst forest and wetland in a 600-acre area known as “The Desert” at the Memorial Forest of Sudbury Valley Trust. Come observe this special plant community and its associated wildlife while learning about efforts to restore fire-dependent sandplain habitats through prescribed burns. This Native Plant Trust easy hike will also feature red pine and black huckleberry. The walk will be led by Neela de Zoysa on May 11 from 10 – 1, and is $51 for NPT members, $60 for nonmembers.

Monday, April 8, 1:00 pm – 3:00 pm Eastern – Riparian Communities, Online

River shores and stream banks have unique riparian vegetation that is adapted to changing water levels. In this Native Plants Trust virtual program on April 8 from 1 – 3, we will follow the Sudbury and Assabet rivers from the watershed’s headwaters in Westborough to its junction with the Merrimac River in Lowell with Neela de Zoysa. Along the way, we will encounter Atlantic cedar swamps, floodplain forests, shrub swamps, emergent marshes, and oxbow lakes as well as the species that characterize them. We will also learn about threats posed by dams, clearing, and pollution.

Please note: We do not make video or audio recordings of classes or programs available after the fact, because we believe education is interactive, with instructors and students building a community and culture of learning. Some programs may be recorded strictly for instructor-training purposes.

Saturday, October 28, 2:00 pm – 4:00 pm – Vines and Creepers

Wetland and disturbed areas are often a tangle of woody and herbaceous vines, creepers, brambles, and briars. Ever wondered about the differences among these groups of plants and how they twine, creep, climb, and scramble? Learn to identify a dozen species on this easy walk through successional vegetation. This field trip is sponsored by Native Plant Trust and will be led by Neela de Zoysa on October 28 from 2 – 4 at Wolbach Farm in Sudbury. The Farm is a Sudbury Valley Trustees property. $30 for NPT members, $36 for nonmembers. Register at http://www.nativeplanttrust.org/events/vines-and-creepers/ Wear long pants.


Sunday, October 1, 1:00 pm – 3:00 pm – Bog Plants

One of Thoreau’s beloved landscapes, referenced often in his writings, Gowing’s Swamp is a rare and beautiful bog in a kettle hole below a glacial ridge in Concord, Massachusetts. Neela de Zoysa of the Native Plant Trust will walk the loop around the bog and explore the thriving community of northern bog plants such as pitcher plant (Sarracenia purpurea), bog rosemary (Andromeda polifolia), bog laurel (Kalmia polifolia), small cranberry (Vaccinium oxycoccos), large cranberry (Vaccinium macrocarpon), and black spruce (Picea mariana). The field trip takes place Sunday October 1 from 1 – 3 at Gowing’s Swamp, a Sudbury Valley Trustees Property. $30 for NPT members, $36 for nonmembers.

Saturday, July 15, 12:30 pm – 4:30 pm – Orchids of New England

Curious about Lady’s-slipper orchids or the rose pogonia, made famous by Robert Frost’s poem? Orchidaceae is one of the largest plant families in the world, and there are 50 orchid species native to New England, from showy lady’s slipper (Cypripedium reginae) to rose pogonia (Pogonia ophioglossoides). While some species are common, many are of conservation concern. This session provides context for understanding native orchid habitats, diversity, and conservation issues. You will learn identification techniques, pollination strategies, and life-cycle stages for native orchids. Learn about the members of this highly evolved plant family and their specialized pollination strategies and interesting life cycles. Botanist Neela de Zoysa will conduct a class on Orchids of New England on Saturday, July 23 at 12:30 pm at Garden in the Woods in Framingham. $60 for Native Plant Trust members, $72 for nonmembers.
