Tobacco Plant Helps Detect explosives

 So the next time you travel, you may not only have to have a body scan, you may also have to walk by planters full of Nicotiana!  Dr. June Medford of Colorado State University published a recent study in the journal PlosONE detailing her team's work with the tobacco plant to help detect explosives.  They have engineered the plant to turn from green to yellow when it detects explosives in the air.

Where Did the Flowers in My Bouquet Originate?

Photo by Carol King
Did you receive a bouquet from your Valentine this year?  Did you ever wonder where the flowers come from?  More than likely the came from Columbia in South America.  Why Columbia you might ask?

Gardener Dave shared this article about why so many of our flowers come from there.  In 1967 David Cheever, a graduate student in horticulture at our very own Colorado State University, wrote a term paper titled “Bogotá, Colombia as a Cut-Flower Exporter for World Markets.” After graduating, Cheever put his theories into practice. Cheever’s paper and business efforts started an economic revolution in Colombia.

Great Plant Ideas at the Garden and Home Show by Duane Davidson

When you visit this year's Garden and Home Show, be sure to stop by the Educational Garden presented by Colorado State University. The CSU garden offers plant suggestions for every exposure in your landscape: north, south, east, and west. The center island in CSU's garden is divided into four sections, one for each type of sunlight and weather exposure. In each section are samples of plants suggested for that location. Many of the plants are in early bloom, as well, so you can get a better idea of how well they might fit into your yard.

On the sides of the CSU garden are plants for shady locations, plus a sampling of the many plants selected for the Plant Select program (which identifies plants that do well in our area), and a colorful display of spring-flowering bulbs.

The garden is staffed by Colorado Master Gardeners from the Denver area, who answer questions about the various plants and any other horticultural problems that visitors pose to them.

The show continues through Sunday, February 20. It is open noon to 8 p.m. on weekdays, 10 a.m. to8 p.m. on Saturday, and 10 a.m. to 6 p.m. Sunday.

Here's a slide show for you to enjoy!

14th Annual Great Backyard Bird Count

Photo from National Audubon Society
The Great Backyard Bird Count is an annual four-day event that engages bird watchers of all ages in counting birds to create a real-time snapshot of where the birds are across the continent and in Hawaii. This is a great event for citizen scientists and their families help the researchers at the Cornell Lab of Ornithology and the National Audubon Society learn more about how the birds are doing—and how to protect them and the environment we share. You can report your findings at www.birdcount.org.  This year the event will be held from February 18 - 21, 2011.

African violets –not just foliage plants! by Elaine Lockey



It seems that you either have luck with African violets blooming or you don’t. I was in the no-luck category for many years. I had one particular African violet for more than 5 years with one tiny little flower the entire time. I guess I was keeping it for the cute fuzzy foliage as I’d given up on flowers. What was the secret of my non-gardener friends who could produce gorgeous blossoms on theirs?

Did the Cold Kill the Pine Beetles?

The recent cold, cold temperatures has everyone talking and hoping that it was cold enough to kill the mountain pine beetle.  Sadly, the answer is no. "We need it to be sustained, at least two or three weeks" with temperatures of minus 20 or lower, U.S. Forest Service spokeswoman Janelle Smith said. "These short cold snaps will not do the job."

On a positive note, if it had occurred to you to put your wool garments outside during the cold snap, it would have kill any moth egg larvae that might have been present!

Fluxuating Temperatures Wreak Havoc in the Garden by Heather Hodgin

A Garden Affair
Endless Summer Hydrangea
Baby its cold outside, and you’re not kidding. According to the National Weather Service, the last time that Denver had a high of minus 1 or lower was January 12th and 13th in 1997. Maybe like me, when you heard the prediction for the metro area sub zero temperatures, your thoughts flew to your (insert name of perfectly lovely, but only semi-hardy plant here). With dread, you worried what that naked spot in your garden would look like next year and fell into a deep pit of despair.

Weather – Workin’ the Swing Shift by Patti O'Neal

What is a plant to do?  It is late January and all but a few plants should be peacefully enjoying the delicious dormancy of winter.  In the restful sleep of hibernation each plant sends good thoughts to its root zone where precious nutrients are stored, to be called on when the the sunshine of spring and early summer tease them to life by warming the soil and sending messages of new growth.  That’s in a perfect world.  But this year we are experiencing anything but perfect. 

Temperatures have fluctuated from 70 degrees to below 0 in a span of 3 days.  This has happened several times since December.  Then we go back up to high 40’s for a week at a time with lows only at freezing, creating a freeze thaw situation in the soil.
