Don't Miss It! Week of November 7th

This time of year, a little inside and a little outside is where I want to be; it all depends on the weather. Luckily, either way I have something to see and something to learn. • Is This Tree Dead? No, actually, it is a Larix sibirica or Siberian Larch, which is a deciduous pine tree—that is, it loses its needles (more correctly called leaves) in the fall and sprouts new...

New Species to Colorado Discovered

Because identification of mushrooms is so difficult, it is believed that only a very small percentage of existing species are even known to science.  Hence, identification by visiting experts is critical for any herbarium to determine if previously collected specimens might have been misidentified, or to update names that have been changed.  Dr. Bates has extensively studied the Gastromycetes (puffballs and their allies) in desert areas of Arizona and has...

  Some people love snow. My idea of a good winter sport is snorkling--NOT at a local reservoir incidentally...for those of us who love lushness and green, winter can stretch interminably.

• Don’t forget to look down; you’ll notice a lot of low-growing color. Perennial Walk offers a particularly good example of Polygonum, and you can find plenty of low-growing Sumac (Rhus aromatica) spread beneath the trees in the Ponderosa Border.

Overwintering Hardy Aquatic Plants at Denver Botanic Gardens

The most pressing concern of the Gardens' visitors each summer relates to what we do with our aquatic plants during the winter. The horticulture staff is now challenged as construction continues with the dynamic restructuring of our Gardens. Although we must make adjustments in over-wintering plants, the same principles apply. Hardy waterlilies are hardy to zone 5a (USDA Plant Hardiness Zone Map) and can be over-wintered in Denver by lowering the...
