Professional Conferences and Trade Shows = More Plants, People and Gardens
By Debra Knapke
I have been attending the Annual Symposium of the Perennial Plant Association since 1992. This conference is held in different locations in the United States and Canada. It combines education sessions and tours geared toward designers, growers and retailers for whom herbaceous perennials are a part of their business focus. I have visited many prestigious Botanical Gardens and Arboretums and countless private gardens that are not often open to the public. This year, I travelled to Minneapolis, and this was the best yet (I say this, every year).
Below is a very small sample (out of 110 images) of what I experienced in early August.
Plants, Plants and more Plants
Sages are among my favorite plants: gorgeous flowers, hummingbird and other pollinator attractors, herbal uses, and easy to grow. Above is one of the Brazilian sage species (Salvia guaranitica ‘Amistadt’). Its electric purple blooms call you from across the garden. An older sibling (below) is Black and Blue sage (Salvia guaranitica ‘Black and Blue’). When you grow this sage in your garden be prepared to be strafed by hummingbirds if you happen to be weeding when they wish to feed.
From time the time, the experts are stumped. This lovely little annual had many of us asking: “What is this?” When we found a docent who had the plant list and learned that we were looking at a large-flowered laurentia (Isotoma axillaris ‘Avant Garde White’), there were more than a few sheepish expressions. The flowers were approximately 1.5” in diameter – they are usually much smaller – and they danced in the breeze. And, another plant goes on the list for next year!
Alliums are another useful plant in the garden. One downside is their excessive seeding. After three to four years, you may have only alliums in your garden. Enter some of the new hybrids that make few to no fertile seeds. Pink Planet allium (above) is one of those new hybrids; Millennium is another – Millennium allium is now in my garden. I will let you know about its fecundity.
At Kelly and Kelly Nursery, we saw what patience and vision can achieve. Need a fence? Create a ginkgo espalier. If you start this project now, you can have this in 10 to 15 years, or so.
I would be remiss if I didn’t include a picture from the edible garden at the Minnesota Landscape Arboretum. If you are looking for the tastiest crabapple for jams and jellies then Dolgo crabapple (Malus ‘Dolgo’) is your tree. What is the only difference between a crabapple and an apple? The diameter of a crabapple is two inches or less; an apple is larger than two inches.
Not all of the plants we see are in pots or gardens. The Minnesota Landscape Arboretum has an extensive collection of rare books in its library. This gorgeous lily was hand-colored and sold in limited folios to those who could afford books back in 1542 — 50 years after Columbus sailed the ocean blue. (De Historia Stirpium, Leonhart Fuchs, 1542)
Plants are the designer’s medium. We use the tools of line, form, texture and color to create borders, beds and vignettes. We make places of order, activity, privacy and repose. Here is a border that is peaceful and textural in nature.
… while this border is a riot of hot colors. It also happens to be complimented by a “Big Bug” assassin bug.
Speaking of insects: bee hotels have been making appearances in all the best gardens. I’ve seen recommendations for creating tubes from paper or thin cardboard. If you look closely, you can see that all of the materials in the houses are from the garden: small drilled branches and herbaceous plant stems that are usually relegated to the compost pile. Here are two versions — a multi-level hotel and a simple bee hostal.
Being a plant addict is not a hopeless condition. There are times when something other than a plant grabs my attention. This green tree frog nestled in a ligularia leaf may have been one of the most photographed garden visitors on the garden tour. Of course we were discussing the perfect color harmony of the reddish-brown markings on the frog with the veins on the leaf. Get a bunch of designers together and what do you get? Endless discussions of color, form and texture in the garden!
Wishing you a beautiful fall!
Love them all! Especially the ginkgo espalier.
