Hello, everyone – I hope this finds you all happy and healthy and ready for Spring. This past Thursday marks the end of one of my two science classes this semester. It was a class condensed into half a semester and, although it was not a difficult class for me, I’m glad to finally have a little bit of wiggle room in my schedule and taking that final was a load off my mind, literally.

Also, I seem to have made it past the most difficult part of my biology class. The first half of this semester felt like trying to run through pea soup. Today, it’s rainy and windy and flowers are blooming…all those little signs of Spring are recharging my batteries and the world feels less oppressive and serious.

There haven’t been many opportunities to get outside with my camera, so I’ve been clicking with my iPhone on the run, which is the source of all the pictures I’m sharing today. The tulips are especially exciting because I planted them this winter just so I would see them during the semester when I don’t have time to garden. Turns out, I did the right thing and I’d like to thank myself for the forethought. Thank you, self!

One of the most wonderful things that happened turned out to be a very quiet personal moment in the middle of a difficult biology exam last week. We have been mired in chemistry for the last few weeks and I was getting lost in the details and hadn’t been outside in what seemed like forever. I missed gardening and it felt like I would have my nose in a textbook forever and ever…So one of the test questions was to write out in great detail the process of photosynthesis, paying special attention to the part when energy from the sun is transformed into chemical energy in a plant. I took a deep breath and began….”A photon of light from the sun is captured by a complex of light-absorbing pigments embedded in the thylakoid membrane of a chloroplast located in the cell of a leaf.” Somewhere in the middle of writing that sentence, I heard the poetry. I suddenly remembered why I was there in the first place and what all the work was for. The rest of the answer flowed out of me like the lyrics to a favorite song. It was one of the happiest moments EVER! The section on photosynthesis is over and we’re moving on to genetics, but that brief moment of deep and nerdy bliss in the middle of a test was all it took to put the fragments of ‘me’ back into a cohesive whole. It was a good day. I came home and planted seeds to celebrate and while I was out there, I took the following photo…a million photons of light showering my tulips with magic.

....weathered, yet beautiful...Muir Woods, California - Sept. 2011


Yesterday was an awesome day. There was a big test in Botany, which was my focus for the last week. We have been studying cellular respiration, and photosynthesis. They are very similar, with one being basically the reverse of the other. That kind of fooled me into thinking I was going to memorize it without a lot of pain. I was wrong. We’re talking about 100 different steps and half that number in atoms and molecules of this or that chemical, which dance around and punch each other out until they make molecules of yet more this-y and that-y chemicals. There are no generalities either. Every move, every chemical, needs dissecting and remembrance. There was no high school biology for me, so now that I’ve caught up a little, I find myself thoroughly humbled by the elegant and complicated brew that Mother Nature has managed to cook up. She’s a bad-ass and I wish she would have imprinted this knowledge on my gray matter. Indelibly. Well, it’s over for now and I can catch up on other parts of life. Like my new plant!

..Carnivorous Pitcher Plant...Nepenthis x mixta?


Sunday, Tom brought me a Pitcher Plant. A Nepenthes x mixta hybrid, most likely. These are among the easiest to care for in the carnivorous plant world. This is great because my last try at carnivorous plants did not end well. It was years ago, but I kept the book I bought for reference, since I knew I would someday have another one. The book, “The Savage Garden: Cultivating Carnivorous Plants” by Peter D’Amato is now on my reading list, especially the chapter pertaining to my species. It gets excellent reviews, and I kept it all these years for a reason.

...a pitcher full of digestive fluid. Bwahahahaha!


Carnivorous plants are nothing less than utterly awe-inspiring. Their response to living for millenia in crappy soil conditions, was to modify their leaves into all sorts of contraptions like pitchers, pipes, and snapping jaws. All of this so they can lure insects, and sometimes small rodents, kill them slowly, then live on the nutrients left by the decaying bodies. Plants don’t sit around and whine about the cards they were dealt or envy and get angry at the carrot living in a garden full of luscious, mineral-rich soil. They just take care of business. I have a serious respect for plants.

...Enter at your own risk. Insects, ye be warned!
