When I taught high school biology I had a sign over the door of my classroom that said “Biology is Life”. (I also had a poster with a picture of Charles Darwin and a caption that said “AP Biology: Adapt, Migrate or Die”, but that is another story…) Anyway, I thought my sign over the door was cute. And true.
This week I finally took on the task of weeding out my flower beds and getting them ready for the new year. Really, a simple and somewhat rewarding task, but for me an afternoon of rich classroom memories and an endless rush of biological trivia. It was so much fun, in fact, I thought I’d take all of you on a short trip through my garden. Ready? Here we go!
What a disaster! This garden has several little tea roses, a beautiful English rose, and some nice perennials. Ugh. Mostly I see dandelions…
Clever camera: it focused on the grass instead of the flower. (and my biology brain reminds me that the grass is a monocot and the dandelion is a dicot. Thanks bio buddy…) Oh, well. You can still make out the bee in the flower, can’t you? We think of dandelions as pests in our gardens (well, I do!), but they are actually early blooming plants and an important source of food for bees and
my personal favorite (after bumblebees) the ladybug. Later on the youngsters from this beetle will help keep my aphid population on the roses under control, so that makes dandelions a good thing,
I know that they are good for the wildlife, but I still have to get rid of these darn plants so my roses can shine. Look at this puffball of seeds (dandelions use wind as a dispersal strategy chants my brain… The seeds can survive up to 5 years and help the plant population survive fires…)
and the root! I’ve been told that the root as also an adaptation to help the plant survive prairie fires. Don’t know about that one, but we all know we need to get the root out or the plant will come back. (That root is a tap root . Thanks biology brain…)
Oh, wow. A pill bug! I love these guys. I would teach my AP Biology class how to make potato traps and assigned them the homework of catching 10 bugs over a weekend so they could design experiments using them in little choice chambers. The students learned how to design controlled experiments, drew conclusions about animal behavior, and the bugs had a fun outing and all the potato they could eat. It was fun, really. (Arthropods, crustaceans really, says the ever intrusive biology brain.) Over the years so many bugs were released in the flower beds at the front of the high school a robust population could be counted on to bail out any student team that forgot to do their homework.
Exactly the same type of thing happened at my house where yearly infusions of classroom earthworms established many happy garden occupants. (Annelids, says the brain. If you accidentally cut them with the shovel they will probably make it, but not as two new worms. ) My students loved to name and race their worms. If you put them in your hand you can feel the little bristles on their tummies (Setae! Thanks, brain.) The bristles anchor the worm as it pushes forward in the soil. Kind of like wax on cross country skies…
The English rose has a mature rose-hip with seeds in it. Look at these guys. I wonder if I can get them to sprout and grow. (…the seed is really a baby plant and the food it needs to grow. The food part of the seed is double fertilized so it has more copies of the roses’s chromosomes than the rose plant does. Roses, unlike humans, can have different chromosome numbers… shut up biology brain. Enough!!)
The weeding is done. You can actually see the rose plants OK now. They all came through the winter in good shape and are putting out new growth. The largest rose is my Princess Alexandra of Kent rose, and it has started growing the first buds. All is looking good. Time to mulch, feed (plants need the elements in fertilizer to make more proteins and to copy the DNA in their cells so they can divide… yep, the brain is still going…) and get to work on the other jungles gardens.
Rich with life, details and memories, my gardens are once again growing.
Biology is life!!
