Painting With a New Brush

Texas Indian Paintbrush (Castilleja indivisa) ~ Brazoria Wildlife Refuge

Of the three Indian paintbrush I found blooming at the Brazoria refuge on January 6, this was the most vibrant and fully developed, with its small, greenish flowers easily visible among the glowing red bracts.

Like other beloved spring wildflowers, particularly bluebonnets and pink evening primrose, Indian paintbrush won’t begin spreading across the land for another two or three months. Still, it’s not uncommon to find isolated blooms as early as January, and this isn’t the earliest I’ve found. Although somewhat stunted and less colorful, another paintbrush had contributed to nature’s artistry on January 5 in 2018.

Truly Wild Flowers

Carolina larkspur (Delphinium carolinianum) ~ Rockport City Cemetery

If you think this larkspur seems unusual, you’re quite right. The mass of blooms, the unusually flattened stem, and the sheer size of the plant — nearly sixteen inches of floral exuberance — are clues that the plant is fasciated: a relatively uncommon condition that produces a variety of abnormalities in the plants it affects.

Sometimes, there is fusion or flattening in the plant — usually in its stem — that results in ribbon-like, coiled, or contorted tissue. Banding at the top of plants can cause them to increase in size and weight, while flowers and leaves growing on a fasciated plant’s flattened stems may be smaller than usual, or more more abundant, as with the larkspur I found at Rockport.

Fasciation has been attributed to a number of causes: genetic mutation, the presence of bacteria, fungi, or viruses; the activity of insects; or even weather conditions such as frost. Any physical damage to the growing point, or apical meristem, can lead to quirks in the production of new flowers, leaves, or stems.

Plant meristems usually produce the round or cylindrical stem we’re accustomed to seeing. In fasciated plants, the meristem flattens out and becomes elongated. Instead of producing a round stem, the mutation causes a flattened stem to develop.

Here, a fasciated and top-heavy Indian paintbrush (Castilleja indivisa) shows off its own flattened stem and remarkable size while lying on the ground; unbroken, it had been brought low by the weight of its own growth.

Here, the banding typical of fasciated stems is obvious.

Looking more like a chrysanthemum than an Indian paintbrush, this remarkable collection of individual blooms and colorful bracts had grown to be more than six inches in diameter.

It may be a bit of a commonplace, but it’s impossible to see these botanical anomalies without saying, “Fasciation is fascinating.”

A Sweetly Tangled Season

Indian paintbrush and mixed grasses

Three primary components of Texas’s famous spring floral displays — red Indian paintbrush, yellow ragwort, and bluebonnets — often cover the landscape with grand, monochromatic sweeps of color.

The fields are dramatic and beautiful; they draw visitors from across the state and beyond to exclaim over them. But on our back country roads, I find myself equally attracted to the fencelines, where the flowers — tangled, half-hidden by rising grasses, often ragged or beginning to fade — present a different sort of picture.

Part of their charm is their small scale, and their easy willingness to mix with other species, including humans. You almost can hear them saying, with just a bit of a twang, “How’s about ya’ll sit a spell, and we get to know one another?”
