Perennial Gathering

Just back from the Perennial Plant Association meeting in Lancaster, PA, held in person for the first time in three years. It was like a family reunion after such a long period of no contact, except via Zoom. Over 450 people from around the world showed up for the first year back.

The Perennial Plant Association is a professional organization for people involved in production, sales, trials, research, landscaping, or growing perennials. The annual meetings consist of a week of talks, tours, and a trade show. There are plenty of tour options, so attendees can select whether they are more interested in landscape design, retail, or production.

Aris Greenleaf is a large liner producer, who also has a trial garden. Sadly, non of the trial plants here had been planted more than a few months.

Cavano’s Nursery in nearby Maryland, was one of several top notch perennial growers we visited.

North Creek Nursery, a leading producer of native plant liners in PA, hosted the group for an amazing dinner

Owner Ed Snodgrass welcomed the group to his Emory Knoll Farms, an “off the grid” nursery that only produces plants for green roofs. 100% of their power is produced by solar panels on site.

For those unfamiliar with green roofs, shingles are replaced with plants, which help insulate the structure, while also reducing runoff.

What interested many on this tour, was their use of an outdoor version of a Stanley Steamer, for weed control. The manufacturer, Weedtechnics is out of Australia, but has a few US distributors.

Steam is applied too kill weeds as you would clean a carpet. The steam only penetrates the ground to 5 mm, but that’s enough to kill both the weed and weed seed, without bothering nearby plants. This is certainly a technology many of us on the tour will be investigating.

We visited the amazing Mt. Cuba Center in Delaware, a place I’ve had the pleasure of visiting several times over the last 30 years. The gardens have undergrown a dramatic facelift that made a great garden even better. It was great to catch the native Zigadenus glaberrimus in full flower by the lower pond.

The amazing Chanticleer Gardens and Longwood Gardens both hosted the group for two incredible dinners and a chance to stroll the grounds. At Chanticleer, we caught the water lotus (Nelumbo) in full flower, looking eerily like something from the Little Shop of Horrors.

Of course, we are all there to see the latest and greatest in new plants, and these gatherings never fail to show us something new we need to try. Below are the latest from the world of echinacea breeding.

Lysimachia lanceolata ‘Burgundy Mist’ and Sorghastrum nutans ‘Golden Sunset’ are two new US natives that are just hitting the market.

Of course, in addition to the plants, these meetings are also about the people and the networking that these meetings afford. It was great to see two former JLBG’ers in attendance, Adrienne and Jon Roethling. Adrienne is now the Director of the Paul Ciener Garden in NC, and Jon heads up the grounds at Reynolda House and Gardens.

And it was great to catch up with Simple, the Roving Garden Artist…one of the most “out of the box” designers I’ve ever had the pleasure of meeting.

It was a lovely surprise to run into an old friend, plantsman Barry Yinger, who was in town, taking a break from his Sanseveria conservation work in Tanzania to visit his sister, and happened to be staying next door to the convention.

It’s always great to catch up with old friends, Nanci Allen (long time PPA director), and Allan Armitage (retired UGA professor). You never know who you’ll run into at these meetings. If you work in the field, check out the PPA, and perhaps we’ll see you at a future symposium.
