Suburban Serengeti
Safaris are expensive.  So why not trade the very large for the very small?  Stay away from tourist traps and take a trip into your back yard for action worthy of television special—you won’t even need to pack a lunch. Even if at first glance the average home’s yard and garden might seem virtually free of animal life, a closer look shows how wrong first glances can be.  Arthropods—members of the...
So Your Garden is Rusting
As we swing into high summer and garden plants kick into overdrive, the fungi, bacteria, and viruses that rely on them start making appearances too.  These plant pathogens manifest themselves in many ways, from the elegant to the grotesque. Rust fungi are one common pathogen that show up with warmer temperatures.  These fungi—along with a related group known as "smuts"—are some of the most destructive plant pathogens. Rusts and smuts...
Plant Conservation Day
Join us in the Gardens on Saturday May 19 to celebrate Plant Conservation Day. The third week in May holds many opportunities to celebrate our rare and native plant species in Colorado.  Not only is it Celebrating Wildflowers week, a week to get out and enjoy wildflowers in bloom on public lands in your area, but Endangered Species Day and Plant Conservation Day fall within the week as well. We invite you...
It's Euxoa Time
  Plants aren’t the only thing becoming more active this time of year.  Warmer weather triggers a lot of invertebrate activity, and you may be noticing that your home is suddenly (apparently) some sort of transcontinental superhighway for arthropods. Which is just one of the reasons that I love springtime.

Timing is Everything
Few things signify spring like trees covered in blossoms.  Spring so far has been on the early side, thanks to our warmer than usual temperatures through March.  Many species that would oftentimes only be beginning to bloom at this time of year are already finished flowering—they seem to think it’s already May in Colorado.  Still other species haven’t broken bud, and look as though we’ve had a month of today’s...
Do Plants Grow Old?
At first glance it seems obvious that plants age right along with everything else on planet earth.  Everyone can recognize an old tree. But is ageing really the same as being weather-worn? Compared to human ageing, where progressive deterioration of physiological function eventually leads to death, plants can hardly be said to age at all. Plants are organized differently than animals. Usually animals complete all their major structures and organs while...
Cherry Blossom Blitz
With the beautiful, warm weather recently I have spent a lot more time outside and have enjoyed watching the first signs of spring every where I look. My chives are coming up in the garden and my lilacs are leafing out. Here at the Gardens there are so many plants starting to bloom, from the daffodils to the magnolias. Observations like these make up the science of phenology.
Ah, Spring!  The North Takes a Deep Breath
One of my earliest science class memories (and maybe one of yours, too) is learning that people and other animals “breathe oxygen” and plants “breathe carbon dioxide”.  I carried this gem all the way to AP biology in high school, when things got complicated.  As it turns out, plants need and use oxygen for all the same things that we do, and they exhale carbon dioxide to boot!  So what’s going...
(World) Water Day is March 22
“World Water Day” conjures up images of far-away problems (e.g. a billion people around the world do not have access to clean and safe water – with more than a third of these people living in Sub-Saharan Africa). If such alarming stats summed up World Water Day, however, the most anyone living in Denver could do would be to send money to an international water charity. Water issues, really, are not...
