Some Garden Observations
The Redbud tree at the nursery was in all its splendor a few weeks ago. When watering some stressed plants under the redbud there was a hum of pollinators that caused me to stop and observe the busy activities of the many winged feeders. This also allowed me to actually look at the flower of the redbud, it looked like a pea flower. I had not observed the flower up close before…key word here is, observed. The individual flowers are small and most of us look at redbuds from a distance and see a tree clothed in blossoms. This time the hum kept me just being a part of the redbud world.
In my readings I found out Cercis (genus name of Redbud) is indeed one of many genera that are part of the Pea Family a part of plant classification. How could redbud be in the same Family as peas you put on your dinner plate? Who would consider redbud and peas closely related? This makes it most confusing for us gardeners that are trying to make sense of the Genus and species and the reasoning behind it, not thinking it goes one step back from Genus to Family.
We can thank Carolus Linnaeus, a Swedish botanist, for the classification of plants and animals. Giving plants and animals a binomial name, classifying with two names, (Genus being the first and species the second). Living in the 18th century he wasn’t aware of Cultivars, which adds another dimension to classifying.
I have a note attached to a wall in my office to help me remember the ways Linnaeus classified; King Philip Came Over For Greek Salad. What does this mean? It’s how all plants and animals on the planet are classified; Kingdom, Phylum, Class, Family, Genus, species.. The one before Genus is Family and that is what puts redbud and peas together, it’s flower type. The most important for most gardeners of the ‘king coming over for salad‘, are the last two, Genus and species. When you go to the grocery store looking for soup, there are too many kinds of soup to choose, so you narrow that down to chicken soup, then you seek out a certain brand. Think of soup as the Family, chicken soup as the Genus and the brand as the species. You may be a gardener that comes to the nursery, sees a plant that looks nice and it becomes part of your garden regardless of Genus or species, others want to know more. Do you really need to know more? Well, it kind of depends on the gardener. The point being do you care what kind of chicken soup you purchase or is chicken soup chicken soup?
You come to the nursery asking for shasta daisy, it seems a simple question but it’s not. There are many kinds of shasta daisy; some are short, some taller, some flower a little later, some early, some with white petals and centers and others with white petals and yellow centers, all cultivars of the Genus Leucanthimum. For a discerning gardener this is important, for other’s, ”I just want a shasta daisy”. I’m sure Linnaeus would have included Cultivars in his classification had he known the direction botany would take us.
I had a gardener in yesterday looking for Pulmonaria (lungwort). I took her to the plant and she said, ”this is just the one I was looking for”. Pulmonaria have many different cultivars, some blooming pink, some a beautiful blue. This gardener knew just the cultivar she was looking for and it had to be that cultivar to match with the others in her garden.
Linnaeus gave us the way to communicate at a nursery that helps us get the gardener the right plant; Genus, species and Culitvar is the language, usually written on the tag. When shopping for plants, keep your receipts in your garden folder, it helps the nursery person to find the right plant to replace one that may have died.
Enjoy the diversity that gardening brings, it’s an ever-changing world. Observe the small things in the forest or the garden. The fun of this exploration is seeing the vast diversity nature has given us. We’ll never learn it all and that’s what keeps us exploring and observing.
