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?

Gardening Quiz: Answer

bromeliad quiz groupToday’s post is the answer to last week’s post, so if you haven’t yet taken a look at that, I suggest you do so now.

So, did you solve my little botany quiz? The correct answer is…

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?

New Year, New Garden Advice

haircare2My, how times change. I remember sitting in my 7th grade health class, watching a film strip (you’re as old as I am if you remember those!) about hygiene. It recommended washing your hair at least every two weeks! An old magazine I recently unearthed advised housewives to put on a dress and make-up to greet their hard-working husbands at the door. And, the book that accompanied PBS’s Crockett’s Victory Garden (copyright 1977) offers a recipe for disaster with their diagram on how to plant a Christmas tree. Don’t blame Crockett, however—his directions followed what was then standard procedure. Yes, we’re always learning something new, even about gardening.

A Gardener’s New Year’s Resolutions (revisited)

I had an idea for a post for today.
Instead I got the flu.
So instead of new insights, I hope it’s okay

A Gardener’s New Year’s Resolutions

Posted on December 28, 2009 by LAH

plants-for-sale-lowes-cs_2008aug02_lah_5106-1Lots of people like to make New Year’s resolutions. Gardeners are no exception. A quick web search turned up plenty of lists, with gardeners around the country vowing to stay ahead of the weeds, thin their carrots, and learn the Latin names of all their favorite plants. If you like to garden, you probably have your own list of good intentions. And if you’re like me, you’ll struggle to keep even one of them.

This year, I’d like to propose a list of gardening resolutions that any enthusiastic gardener can keep. Your garden may not be perfect, but at least you’ll have the satisfaction of knowing you achieved your New Year’s goals.

Photos Make Special Gifts

LAH_3950Today it’s time for my once-a-year photography promotion. Does someone on your gift list go wild for wildlife or bonkers for birds? Do they laud landscapes? Are they passionate about plants? How about giving them  a photo expressing their special interest?

You can visit my online store at mountain-plover.com, view my line of blank greeting cards here, or contact me directly for prints of any of my photos that appear anywhere on this blog. (Note that prints not in stock will take a few extra days.)

Winter in the Gardens

DBG_LAH_3996-001Dead leaves, bare branches, brown grass. It’s hard to create a landscape that looks attractive when everything appears to be dead. Yet, we live in a place where winter can last six months, or more. I want my yard to be attractive all the time, not just during the growing season.

With that in mind, this week I paid a visit to the Denver Botanic Gardens. They’re open in every season, so surely they’ll have ideas for making a garden worth visiting, even in the winter. How do they do it?
