Prairie Agalinis (above)

The Natives are Friendly

A beautiful flower appeared around Texas in abundance last fall. Prairie agalinis, Agalinis heterophylla, bloomed profusely in some parts of the state. This native annual grows from 1-2 ft tall and can at times be sprawling depending on how large it becomes. It prefers full or partial sun and moist sites. The dark green stems are grooved and hairless and branch at an almost 90 degree angle. It has a distinguishing characteristic of 3 lobed lower leaves at the base of the stems. The stems of the annual will turn black as the seeds mature in late fall. When the seed capsules split the wind can carry these tiny seeds a long distance in some cases. Prairie agalinis spreads by reseeding itself and does not reproduce from roots are cuttings. It does however have a fibrous root system and there is speculation that it may have a special relationship with other plants. Agalinis may use some available nutrition from other plants such as the prairie grasses. In return, its dainty vibrant flowers attract native plant enthusiasts into the prairie which then collect the native seeds and disperse them. Agalinis flowers bloom for about a month and are an inch long and vary in color from lavender to purple. There are other similar species such as Plateau Agalinis, Agalinis edwardsiana, and Agalinis tenuifolia, but the color is not as vibrant as Prairie Agalinis. The absence of any attractive floral scent is disappointing. The corolla is tubular in nature and consists of 5 spreading lobes with the inside of the flower dotted with specks of dark purple and 2 little patches of yellow. It is a known larval host for the Buckeye butterfly and the Orange Sallow moth, and a very attractive nectar source for Bumblebees and other long-tongued bees. Prairie agalinis can be found everywhere in Texas except west of the Hill Country and it can also be found in bordering states to the north and east of the Lone Star State. Imagine what a nice surprise it was to find acres of this striking native just ripe for the picking or combining as the case may be. During the recent Blackland Prairie harvest that took place in Bosque County such a site was discovered. What a lovely addition this native would make to any landscape.
