Average Garden Soil
Native Texas Panhandle soils amended with between 2-4 inches compost or other organic and/or amendments.
A good drought tolerant ground cover for use in a border, in a xeristrip or a rock garden. Evergreen grayish green leaves with fine hairs (tomentose). Will grow too tall and gangling in too rich and moist a soil. Some areas of the country have noted Cerastium tomentosum to be invasive, but I have not seen those tendencies here. A good substitute for the annual alyssium. Cerastium tomentosum var. columnae is a commonly available variety.
Typically a Zone 8 plant, the Christmas holiday bulb, Amaryllis, has been successfully wintered over in Amarillo, specifically, the Wolflin area in this case. If you have a warmer, protected micro-niche, try planting your seasonal Amaryllis outdoors, and leave it there well mulched over winter. I 've winter over Amaryllis in my backyard, but it hasn't reliably bloomed. It requires a full sun location and well amended soil to soak up nutrients to be stored in the bulb.
This is not one of the invasive catmints, but it will reseed some and is not as attractive to cats as most catmints. A low growing, sprawling, drought tolerant perennial that projects a hazy blue appearance with its light lavender blue flowers and grayish green foliage. It is aromatic, not necessarily fragrant. A fast spreader and prolific bloomer even in it's first year, it will begin to bloom after six weeks.
Scabiosa columbaria ‘Butterfly Blue’, though first discovered in Ireland, will thrive very nicely in your transition zone as a border plant along turf, where it’ll receive medium to medium high water. Amend the soil well with organic matter for rich blooms and keep it deadheaded to prolong blooms. Afternoon shade is recommended. A little more trouble than usual, but well worth the softening effect this compact, mounded and cheery plant brings to the border; a Perennial Plant of the Year for 2000.
Sedum, ‘Autumn Joy’ is one of those foolproof additions to your autumn garden, so aptly named; for the joy it brings to the autumn garden. Easily propagated by stem cuttings or root division. As with most sedums, afternoon shade helps. Grasshoppers have nibbled at its leaves in early summer without stunting the plant’s flowering ability.
Another tough and pretty wildflower that populates a wide area from the plains of Oklahoma down to the Chihuahua Desert and over to Colorado and Utah. Leaves are lower near the base of the plant from which stems emerge and bloom in late spring to early summer. Yellow rays with a red to brownish center.
Gregg's mist flower is a Southwest native for the partly shaded bed medium to low water-use bed. It's a butterfly magnet, particularly for the Monarch butterfly which passes through about the same time the mist flower is bloom in late summer into fall. Masses of lavender blue flowers top the plant for which it gets it names, the appearance of blue mist. Frequently, butterflies will be seen topping the flowers. Gregg's mist flowers will spread by roots, allow it some room.
Sand lovegrass is a warm season bunch grass typically found in sandy soils east of the Rockies over a wide range of the U.S. The grass clumps themselves are usually 12-18" tall with the plumes rising to 3-4 feet. Will grow in clay and poorer soils. Very pleasing wispy, arching habit with a soft sway and rustle in the wind. Can grow in partial shade. Seed heads are somewhat purple, fine textured. Will reseed. Low or no water-use.
Gambrel oak is a common native oak species throughout the Rocky Mountain foothills and here in the Texas Panhandle as well. Often times it grows more to a tall shrub, with sufficient moisture it can mature into a small tree. Beautiful somewhat glossy lobed green leaves to 3-5 inches long. Beautiful fall foliage. Will put out a profuse amount of acorns. Gambrel oak can form a thicket. Cold, heat and drought tolerant. Inconspicous tiny red flowers appear shortly after leafing and are normally hid by the leaves.
Texas beargrass is a grass-like perennial evergreen plant native in rocky and limestone soils from central Texas to the upper Rio Grande Plains and west to the Trans-Pecos and into S.E. Arizona. Not a true grass, Texas sacahuista is a member of the lily (Liliaceae ) family. It flowers in Amarillo in early April. A short flowering stem barely rises above the many thin leaves. The flowers appear rose or reddish on the outside before opening, are numerous, white to cream colored forming dense vertical clusters.
