One FWG volunteer is reclaiming a wet meadow from invasive species and planting it with sedges, Swamp Milkweed, Meadowsweet, and other local wetland species.

Catherine Shearer, who received a volunteer recognition award from the FWG Management Committee this year (see The FWG loves its volunteers) is waging a war against the invasive species in what we call “the gully” at the FWG. Although this area is important – as one of our few damp areas and highly visible from Prince of Wales Drive – it was neglected for many years, as we just didn’t have enough volunteers to tackle it.
In 2004, when we received a grant to create a Monarch waystation, the gully was chosen as a prime spot for Swamp Milkweeds (Asclepias incarnata). However, lack of volunteers meant that attention was focused elsewhere and the gully slowly filled with our nemesis, Dog-strangling Vine (DSV; Vincetoxicum rossicum). Later, Common Comfrey (Symphytum officinale), which had grown docilely along our entrance road, suddenly invaded the New Woodlot and cropped up everywhere.
The good news: comfrey drives out DSV and is also very attractive to bees, especially bumble bees. The bad news: it spreads aggressively, has long roots, drives out everything else, and has the unfortunate habit of falling over and turning black after flowering.
But, slowly but surely, Catherine is digging out invasives and planting some of our many, many local native wetland species. Her strategy:

This year, we are very lucky to have help from 3 Algonquin horticulture students – Joey, Ahmed, and Thomas – who work with Catherine on Mondays and attend classes the rest of the week. They are a tremendous help when it comes to digging and scything and are opening up more space for Boneset (Eupatorium perfoliatum), more Swamp Milkweed for Monarchs, more sedges for skippers.
Last fall, we also had help from a crew of Carleton U students who spent a whole morning digging comfrey out of an area where we then planted White Meadowsweet (Spiraea alba) and Buttonbush (Cephalanthus occidentalis).
Thanks also to the people who donated plants for this part of the garden, notably Lyse for the magnificent Swamp Milkweeds, Lynn for mature meadowsweet shrubs, Renate for yarrow plants, and Trish Murphy for Big Bluestem (see photo).

When you visit, watch for large clumps of Wild Bergamot (Monarda fistulosa) on the north slope of the gully, along with Black-eyed Susans (Rudbeckia hirta) and Prairie Cinquefoil. Lower down, you might see tall-growing Big Bluestem and, on the south, shady slope, Sensitive Fern (Onoclea sensibilis) and Spotted Jewelweed (Impatiens capensis). Seeing the changes with the seasons, but also the transformation that volunteers are achieving in this part of our garden is a delight.
The rewards of growing native plants
July 4 – Meadowsweet planted last year is just blooming and already the bees have discovered it. A bumble bee is just visible on the right side of this flower cluster.
August 24 – A month and a half after we wrote this blog post, the rewards have multiplied many-fold. Every time we visit the area, we see Monarch butterflies flying back and forth from one nectar plant to another and laying eggs on Swamp Milkweeds and some Common Milkweeds.
Both of us (Catherine and Sandy) are raising Monarch caterpillars at home (to help the population recover by ensuring high survival rates). One week, we released over 20 adult butterflies in the gully, and they are now producing the generation that will fly to Mexico this fall.
The Meadowsweet has finished blooming, but asters are starting, Boneset is in full bloom, and the milkweeds just keep flowering and flowering. Lots of bees, wasps, and other pollinators are having a field day.
