White Gilia. Long-Flowered Gilia (Gilia longiflora) has slender, erect stems, 1-2 feet high, terminated by a flat-topped cluster of tubular white flowers. The flowers have a narrow tube, about 1½ inches long, and 5 broad, spreading lobes. The leaves have threadlike divisions. The plants are very showy when they are in bloom and are especially abundant in sandy regions of Northwest Texas in the late summer and fall.
Few flower groups show such a decided red, white, and blue as the gilias. The group is a large one, mostly of Western North America, and is named in honor of the Spanish botanist, Philipp Salvador Gil. Some of the gilias are known in cultivation and are considered hardy plants of easy culture. The standing cypress may be grown from seeds planted in August or September, or plants may be transplanted in the spring.
DRUMMOND’S PHLOX
Drummond’s Phlox (Phlox drummondii) has rightly been called “Texan pride.” A drive late in April through the post oak sandy region east of Austin to the Brazos River and southeast to Victoria will disclose it in all its glory. The seeds were collected by Thomas Drummond in 1834 and sent to W. J. Hooker in the spring of 1835. Hooker, an eminent botanist, described it from the plants grown from those seeds in the Kew Gardens in London. According to his description, the plants were mostly of a brilliant rose-red with more or less purple in the flowers of some plants and darker red eyes in nearly all. It is quite probable that Drummond collected his seeds in the vicinity of Gonzales, the western limit of his Texas trip, where today wild phloxes which match his description occur in great profusion. The seeds collected may have included some from hybrid plants, as red phloxes with a white eye are found on the eastern edge of the red-phlox area, and the dark-eyed purple and red are found on its western limits in close proximity to the “phlox purple” variety.
The plant has long been a horticultural favorite, and more than 200 varieties have been described, few of which excel the native varieties in size or coloring.
PURPLE PHLOX
Purple Phlox (Phlox drummondii-purple varieties) grows in sandy soil in Central Texas. The variety with the white throat and red-star eye is common in the southeastern part of the state. It is especially abundant in Wilson and Karnes Counties, where extensive masses of purple may be noted in open sandy places among mesquite and post oak trees. This is a very vigorous phlox and produces large stems and flowers. Studies are being made to determine whether these purple phloxes are varieties of Drummond’s phlox or should be called by other names.
The variety with the purple throat and the two white marks at the base of each corolla lobe grows northwest of the range of the red-flowered Drummond’s phlox. It blooms from April to June and seems to withstand cold better than any of the annual phloxes except the dwarf phlox.
