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.

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.

July Jamboree

Here are a few photos of JLBG in early July…hope you can join us for our upcoming Summer Open Nursery & Garden Days, July 15-17 and 22-24, 2022, and see what’s possible in a summer garden. The nursery will also be open for attendees to shop while on-site.

Be sure to take part in our free Gardening Unplugged talks, which are held each day during the Summer Open House at 10am and 2pm, just meet at the welcome tent.

Calling all Plant Nerds

Just over a month remains before the 2022 Southeastern Plant Symposium kicks off in Raleigh at the Sheraton Hotel, downtown. This joint venture between JLBG/Plant Delights and the JC Raulston Arboretum brings together the top horticultural speakers from around the world to regale attendees with tales of their favorite new plants. Each symposium rotates a focus on either on woody plants, perennials, or geophytes. The 2022 symposium is perennials focused.

The dates are Friday, June 10 and Saturday June 11. Both the JC Raulston Arboretum and Juniper Level Botanic Garden/Plant Delights will be open for visitors on the Thursday prior and the Sunday morning after the symposium.

A few of the amazing speakers include:

Leftherios Dariotis – If you’re a sports fan, you’ve heard the nickname “Greek Freak” applied to NBA star, Giannis Antetokounmpo. Well, Leftherios (aka: Liberto Dario) is to horticulture, what Giannis is to basketball…a true superstar. Leftherios will travel from his home in Greece to dazzle you with an array of little-known plants that thrive in hot, dry climates.

The House of Plant Science

We recently attended the dedication the new Plant Science Building at NC State. This $160 million dollar facility will house high level plant research where interdisciplinary researchers will work together to solve high level plant concerns. I can only imagine being a student and being able to work in such an amazing facility. The top floor is a high-tech greenhouse.
