The Flutter of Fall by Patty G. Leander

So long, mosquitoes! One of the reasons that fall gardening is such a wonderful season is because {most} pests tend to quietly fade away this time of year, and the one I am happiest to see go is the mosquito. It’s hard to think of anything that sucks the joy out of being outside more than a single, determined mosquito. Good riddance. I hope their annoying buzz and bite is waning in your outdoor environment as well.

Butterflies love Gregg’s mistflower (left) and tithonias (right).

As the mosquitoes retreat the butterflies arrive in throngs, fluttering gracefully among the flora. We’ve been enjoying the queens and monarchs while they’ve been enjoying the bright orange tithonias in my garden. I highly recommend planting tithonias next year; they are easy to grow from seed and tolerate hot and dry conditions. A good match for summer in Texas!

Butterflies are drawn to the vivid orange blooms of tithonias.

I planted mine in the vegetable garden in late March, between some pole beans and peppers, and they bloomed all summer, growing even taller than the 6’ trellis nearby. They outgrew their space and I had to pull them up in early September to prepare for fall planting; with no effort on my part they reseeded and the resulting plants burst into blooms a few weeks ago. They will bloom until frost, providing a bright accent in the garden, nectar for the butterflies and cut flowers for the house.

Another enjoyable aspect of fall is the seasonal color in the landscape. Just as wildflowers herald spring there are certain plants that announce the arrival of fall in Texas. Year after year, schoolhouse lilies, also known as Oxblood lilies, dutifully pop up, usually sometime in September, along with fall asters, Maximilian sunflowers, Mexican mint marigold and native ornamental grasses.

The rhythm, color and seasonality of plants is amazing and people who say that Texas only has two seasons – green and brown – just aren’t paying enough attention.

Ornamental grasses look their best in fall but not all grasses are native to Texas. There is one type of non-native grass in particular that I have noticed everywhere this year along roadways, medians, fields and even in my own backyard.

It’s called KR bluestem, a clumping grass native to Europe and Asia that was found growing on the King Ranch in the early 1900s. For years it was incorporated into seed mixes that were used for soil erosion and forage, but it outgrew its usefulness when it started “messing with Texas”, spreading to unwanted areas and threatening to overtake wildflowers and other native species.

If you find this grass in your landscape don’t let it go to seed. Mow regularly, before seed heads form and dig out clumps if feasible. Keep your lawn watered and fertilized so it can outcompete any KR bluestem that tries to move in.

Keep KR Bluestem mowed so it does not have a chance to reseed.
