Go for the Green

In honor of today being St. Patrick’s Day, I thought I’d celebrate “green” in the garden. No, I don’t mean about being environmentally friendly, although that’s certainly important. I’m talking about just plain green… as in chlorophyll-laden leaves.

This time of year, I’m pretty frantic for anything green. There aren’t many broad-leaved evergreens that tolerate Colorado’s winters. Even the conifers are more a blackish-olive drab—not nearly as nice as the “pine” of the decorating industry. Cold weather does that to leaves: many junipers turn plum-purple in winter. Leaves should not be that color. (Mahonia wears the same hue, but manages to look more attractive in it.) Hardy ice plant glows red, and ornamental grasses shimmer in copper and gold. Mostly, however, things look dull grayish brown, or just plain dead.

Winter Containers

Containers in winter_DBG_10200118_LAH_6918Winter used to leave a huge hole in my garden. Containers that were once jammed with vibrant annuals were reduced to pots of old potting soil. Flower beds that had hosted brilliant orange marigolds and salmon-pink petunias had become boring expanses of brown dirt. At least I covered the soil with a layer of mulch—shredded leaves, dried grass clippings, pine needles—but it all looked so depressing.

Not any more. A spontaneous trip to the Denver Botanic Gardens last March gave me the inspiration I needed to make my winter landscape far more interesting.

Angelina Stonecrop – Sedum rupestre ‘Angelina’

sedum-rupestre-angelina_dbg_10200118_lah_7253xAngelina Stonecrop is a garden asset all year long. In summer, the low-growing succulent forms spreading mats of cheerful yellow-green, adorned with clusters of yellow star-shaped flowers. These blooms attract butterflies. But it is in winter that Angelina really shines, when those same fleshy leaves turn an incredible, brilliant orange, with subtle shades of red and yellow. The colors are so intense, the ground appears to be on fire. Such a show would be welcome at any time, but is especially appreciated when everything else is dead or dormant.

Living Christmas Trees

With the surge in environmentalism, many people are trying to decide which is “greener,” a real Christmas tree or an artificial one. Both have their pros and cons. There is, however, a third alternative. You can decorate a still-living tree this year.

Most nurseries and garden centers sell potted Christmas trees. You bring them indoors for a brief spell (a week at most) during the holidays, then plant them permanently in the ground.

Still-living trees cost more. No one wants to pay a premium for a tree that still has roots, only to have it die after moving it outside. While planting a Christmas tree isn’t difficult, you should do the same research and preparation that you would do when choosing any tree for your yard.

First of all, make sure you have the right tree for the right place. Consider how the tree will fit into your overall landscape plan. Most evergreen trees get very large. That cute three-foot fir may have a mature height of 70 feet or more! Instead of trying to cram a giant into a small suburban yard, choose a dwarf specimen instead—or arrange to plant it elsewhere so it will have room to grow.
