Texas Native Plant Week is October 19-25.
How ‘green’ is your garden? Well, now may be last chance this year to plant seeds of wildflowers native to your region that will give you low-maintenance blooms next spring and all summer long. Not only will they thrive — they’ll support native birds, insects and other pollinators that depend on familiar, home-grown species for a healthy ecosystem.

“Native species evolved in the local environment and have developed
complex interrelationships with other area plant species as well as fine tuning
to local climate and soil conditions,” says
Kathleen Blair, an ecologist at Bill Williams River National Wildlife Refuge in
Arizona. Exotic plant species — non-natives, including many commercially available
garden flowers — haven’t. That means, she says, “If you plant non-native or exotic
species, a whole lot of other local species cannot use them.”
It’s possible that going native might help save a local ecosystem,
or at least parts of one. That’s what motivates Pauline Drobney, a biologist at
Neal Smith National Wildlife Refuge in Iowa, where the staff is working to restore
the globally threatened tallgrass prairie savannah. Each year, says Drobney, staff
and volunteers plant up to 250 species of native plants on the refuge. Does planting native mean sacrificing flash and drama? No way,
says Drobney, who won over a skeptical neighbor by showing him the butterfly milkweed
and blazing star in her yard. “It was just knock-your-socks-off color,” she says.
Some non-natives or exotics have become ecological nightmares,
escaping backyards to rampage across entire regions, choking out native species
as they spread. Purple loosestrife (Lythrum salicaria, native to Europe) is a prime
example. “It’s a nightmare of a plant. It’s now clogging up the wetlands of the
East Coast,” says Blair.
Beyond that, planting an appropriate species will improve your
odds of success. Some wildflowers are highly site-specific in terms of
rainfall, elevation and soil type.
Here are just a few examples of some native wildflower favorites
by region:
Great Plains/Prairie: blazing star, cream gentian, fall sunflower,
prairie phlox, prairie violet, heath aster, bird’s foot violet. (“Not only does
it bloom profusely, but it’s the obligate host food for the rare regal fritillary
butterfly,” says Drobney about the last plant species.)
Southwest: lupin, beard-tongue (or penstemon; a real hummingbird favorite)
Chesapeake Bay watershed: butterfly weed, Joe- Pye weed (also
known as trumpet weed), eastern or willow bluestar
Southeast: bee balm, black-eyed Susan
Pacific Northwest: broad-leaf lupine, spreading phlox
Upper Plains: rigid goldenrod, wild lily
Northeast: blue flag iris, New England aster For reliable information on plants native to your
region, consult your local native plant society.
