November Littles: Seeds, Pods, Silk, and Wings

December 14, 2023

As the Fall season rapidly came and went, and the first snows blanketed the landscape, I focused my hiking time (and some of my drawing hours) on collecting local native seeds. Always careful that plenty of seeds remained available for overwintering birds, I still managed to harvest hundreds from about 25 plant species.  All sorted and packaged in separate pill containers, my collection is now stored in the refrigerator at 40 degrees, until growing conditions are optimal for planting.  This treatment method is referred to as stratification.**

Why collect native seeds? All throughout the Spring, Summer and Fall, a diverse assortment of pollinators visited our locally blooming wildflowers and shrubs. Along with these butterflies, moths, bees, wasps, beetles and flies, were the insects, spiders, and birds that prey on unwary pollinators. Such an amazing show; a kaleidoscope of colors and shapes! The air was a buzz with activity. My goal is to mimic the native banquet in hopes of attracting these pollinators and predators. 

Also, seeds are absolutely fascinating. I like to think of them as gift-wrapped, living plants-to-be. Tucked neatly inside of the seed coat are food stores enough to feed the makings of a complex root system; flowers, leaves, stems, branches and even a trunk. Seeds can be tiny, some microscopic and some as large as a softball. Seeds come in a variety of shapes, colors, textures and decor both inside and out. Some seeds have “wings” to fly; some have silky or puffy “feathers” to float; some are like “lead,” heavy enough to intentionally sink under water.

So I pulled out my 10x hand lens to investigate, drawing most of the seed species in my collection. It was very cool to compare seeds of different species that are in the same family (like the composites of the Aster family and the penstemons of the Plantain family). Until creating this journal page, I’d never held the seeds of 3 different species of yucca in one hand at the same time. Observing the similarities and differences, I finally confirmed in my mind that the genus Herperaloe and Yucca are indeed in the Agave family. And then I found examples of seeds from completely different families that evolved similar dispersal mechanisms (convergent evolution). This phenomenon was visually obvious in the delicate feathery, silky, and poofy hairs or bristles attached to grass, aster, and milkweed seeds, facilitating seed dispersal by wind. 

Finally, I felt the need to draw the seeds in case they happened to spill into one big jumble while being planted! Yes, I would be clumsy enough to create chaos out of order. Should that happen, I’ll be able to sort the mess by species by referring to my field guide page.

** Seed-producing plants pass along to their seeds the specific requirements(s) necessary to break dormancy and germinate. These genetic codes determine if optimal conditions exist for seeds to sprout and hopefully grow to maturity. But key to successful germination depends on seed ripeness (in most cases). Knowing the plant species from which a seed is produced; whether the plant is an annual, biennial or perennial; habitat, moisture needs and the type of  “treatment” method(s) are all important bits of information tied to successful germination. 

I’ll have to create a future post describing the variety of treatment methods (germination patterns) inherent in the seeds.
