Phloem is for “Phood”

Cercidium  sp. - Palo Verde Tree @PBG 2004apr18 LAH 003Last week’s post about xylem explained how it carries water from the roots to the rest of a plant. But there’s another transportation problem that plants have to solve. As you know, plants make food (sugars) through photosynthesis. (See my previous posts on photosynthesis.) This food factory requires both chlorophyll and sunlight, and can only take place in the green parts of a plant. Usually this means the leaves, although cacti and other xeric species (such as this Palo Verde, above right) often have chlorophyll in their stems.

Botany for Gardeners: Phloem & Xylem

Aspen_EmeraldValley-CO_LAH_4270Today’s (and next week’s) botany lessons are brought to you by “xylem” and “phloem.” You may remember these terms from a biology class, but I bet you haven’t used them lately. It’s time you did. You’ll be a better gardener as a result. Besides, I used to teach biology, and once a teacher, always a teacher. There will even be a quiz at the end.

Like all forms of life, plants have to solve a very important problem: how do you move nutrients and water from one part of your body to another? Animals (at least the more complicated ones) have a circulatory system, but what do plants do?

“Ding” Darling Dreams

White Pelicans_DingDarlingNWR-FL_LAH_6696_filtered-001What do you do when you can’t go birding? After 21 years in the same house, my husband and I are moving. The goal is a smaller house, less upkeep, and more time for birds and photography. But in order to reach that goal, we have a lot of sorting and selling and donating to do. So, instead of strolling down the trail looking for winter songbirds, or driving across the prairies looking for raptors, I’m prowling around the house trying to find an object that will fit perfectly in that space left in the moving box I’m filling.

Trust me, it’s nowhere as much fun.

Gardening Quiz: Answer

But wait a minute. Did you recognize all those plants? Going clockwise from the upper left corner, we have Spanish moss, a lovely orchid, a tropical bromeliad, and a pineapple.

Now do you know the answer?

Beginning Birders Need a Buddy

Aiken Birders_MtEvans-CO_LAH_6401Is there a bright, new bird at your feeder? Have you suddenly noticed the large number of hawks circling overhead? Perhaps one of your new year’s resolutions is to get more exercise, and you need some motivation. There are plenty of reasons someone decides to start looking at birds. However, once you’ve made the decision, or realized an interest, how do you get started?

Recently, I was chatting with a new acquaintance when I happened to mention that I enjoyed going birding. Her face lit up. It turns out that she and her husband, now retired, were looking for something new that they could do together, and had decided to start watching birds. She had a new pair of binoculars and a field guide, but she was feeling a bit lost. Needless to say, we had a long conversation!
