blue salvia farinacea flower

‘Henry Duelberg’ Salvia

Zones 7 to 9

Salvia farinacea ‘Henry Duelberg’ is a stunning plant that is native to Texas and is very easy to grow. It is loved by hummingbirds and butterflies and is highly drought-tolerant. It doesn’t attract deer, making it a great addition to your garden. This plant can grow up to 2-3 feet tall and has flower spikes that are 1 foot long. The spikes are covered with dark, purplish-blue flowers. When the flowers are spent, cutting back the spikes encourages the plant to rebloom. This salvia can be in bloom all season long once it is established. It is perfect for water-wise gardeners, as it is highly heat- and drought-tolerant. The only thing to keep in mind is that this plant doesn’t like wet feet.

Lacy Oak

Zones 7 to 9

Some debate continues about the correct botanical name of this Texas native, but the common name is lacey oak (Quercus laceyi, syn. Quercus glaucoides). A smaller oak, it reaches just 25-35 feet tall and wide, making it more in scale with residential gardens. The tree has a beautiful habit, resembling a miniature white oak. It makes a lovely shade tree and is also perfect in a garden of native Texas plants. Although lacey oak can be grown in east Texas, it is best adapted to the Hill Country and cultivated settings in west Texas. Lacey oak is highly tolerant of heat, drought, and high pH soils once established.

‘Texas Gold’ Columbine

Zones 5 to 8

The Hinckley columbine is a rare plant that can only be found in one area of Texas. It has buttercup-yellow flowers with long attractive spurs and fernlike foliage. A selected variation of this plant is known as ‘Texas Gold’ (Aquilegia chrysantha var. hinckleyana ‘Texas Gold’). It is a perfect choice to brighten up a shady border with its bright blossoms. Although Columbine can have a short lifespan, it can reseed itself if you allow the seedlings to grow. ‘Texas Gold’ can grow up to a height of 2-3 feet and thrives in well-drained soil, part shade, and adequate moisture. It can also tolerate some heat.

‘Lord Baltimore’ Hibiscus

Zones 5 to 9

Who says native plants aren’t well-behaved and gorgeous? ‘Lord Baltimore’ hibiscus has enormous 10-foot-wide, bright scarlet flowers that bloom for an extended period—from July until frost. Once established, this tropical-looking perennial provides years of color. It is versatile enough to use in large decorative pots, in a perennial border, or butterfly and hummingbird gardens. You’ll often see ‘Lord Baltimore’ growing near ponds because it loves moist soil. Growing to about 5 feet tall and wide, the plants die back to the ground in winter but regrow quickly each spring.

Turk’s Cap

Zones 7b to 11

Turk’s cap (Malvaviscus arboreus var. drummondii) is a perennial plant native to southern Texas, that adds an excellent ornamental value to shady areas. Its flowers resemble hibiscus but don’t fully open, giving them a unique turban-like appearance. These flowers come in various colors ranging from red and pink to white and are known to attract hummingbirds and butterflies. This fast-growing shrub can reach a height and width of 3 to 6 feet. Although it might not survive in the northern planting zones of Texas, it can be grown as an annual. Once established, it becomes drought-tolerant.

Cape Plumbago

Zones 8 to 11

Cape plumbago (Plumbago auriculata) is also known as sky flower due to its sky blue blossoms. This tender perennial thrives in the Texas heat and blooms abundantly from May until frost. The flowers bear a resemblance to phlox and attract various types of butterflies. Fortunately, deer are not fond of them. Cape plumbago can be allowed to sprawl as a groundcover or cascade over a wall. It can also be pruned to maintain a neat shape, mounded or trained to climb a trellis. The plant prefers light, sandy soils with good drainage.

‘Mystic Spires Blue’ Salvia

Zones 7 to 11

Salvia longispicata x farinacea ‘Mystic Spires Blue’ is a selection of another popular salvia called ‘Indigo Spires.’ Besides inheriting an excellent compact form, ‘Mystic Spires Blue’ produces more blooms. Loads of blue flowers touched with silver bloom all season long and mix perfectly with other perennials and annuals as part of a colorful border. Tolerant of heat and humidity and rarely bothered by pests or disease, this perennial has no appeal to deer either. Too much love can kill these plants, so use fertilizer and irrigation sparingly. Cut back to about 1 foot after the first frost.

‘John Fanick’ Phlox

Zones 4 to 9

Named for a San Antonio nurseryman, Phlox paniculata ‘John Fanick’ is a beautiful bicolor with lavender-and-pink blossoms. The foliage has a waxy texture discourages powdery mildew, a disease that lesser phlox often succumb to. It has a compact form, growing about 3 feet tall and 2 feet wide, perfect for the middle or back of a perennial border. This perennial also makes good-cut flowers and is lovely combined with ‘Mystic Spires Blue’ salvia. It tolerates heat and humidity. Grow it in moderately fertile, well-drained soil in full sun to part shade.

Chinkapin Oak

Zones 5 to 7

Considered to be one of the most underutilized native trees, chinkapin oak (Quercus muehlenbergii) can grow quite tall in the East but generally remains in the 30- to 50-foot-tall range in Texas. The foliage is lustrous green and, in some years, develops a pleasing yellow, orange-brown to rich brown fall color. This oak is heat-tolerant and, once established, can tolerate considerable drought. Although adaptable, the tree prefers to grow in neutral to somewhat alkaline soil. It attracts hummingbirds and butterflies.

Deciduous Holly

Zones 5 to 9

A delightful small native tree, the deciduous holly (Ilex decidua) is easy to grow and has an extended period of interest. It is fairly adaptable but prefers moist, acidic soil in sun or part shade. The small white flowers are not very showy, but the female plants’ orange-red berries are stunning. After the foliage drops in autumn, the slim gray branches are covered with berries that persist into winter. This is an outstanding choice if you hope to welcome wildlife, especially birds, into the garden. You need both a male and female plant to ensure good berry production.

‘Lowery’s Legacy’ Cenizo

Zones 8 to 11

Leucophyllum langmaniae ‘Lowery’s Legacy ‘ was selected because it flowers profusely and so often. It is a slow-growing woody shrub that will eventually reach about 5 feet tall. The silvery foliage is quite handsome and provides a lovely contrast to dark green shrubs. The violet-blue bell-shaped flowers stand out beautifully against the silver leaves. Compared to many selections of Texas sage, it is less dependent on changes in humidity for flowering and will bloom more often. This sun-lover resents wet feet; be careful to avoid overwatering.

‘Grandma’s Yellow’ Rose

Zones 6 to 9

‘Grandma’s Yellow’ rose (Rosa ‘Nacogdoches’) has whole, deep yellow, fragrant blossoms that repeat from spring until the first hard frost. Growing 4-5 feet tall and about 3 feet wide, every garden should find a place for this beauty. It needs sunshine – at least six hours a day of good light – and regular watering. Of course, it makes beautiful cut flowers. This rose should be hardy in most of Texas, but in Zone 6, it might be wise to give it some winter protection.

‘Blue Princess’ Verbena

Zones 7b to 10

Verbena x hybrida ‘Blue Princess’ thrives in Texas heat. “Most people make the mistake of pampering it,” says Brent Pemberton, Texas AgriLife Research horticulturist. “It must be planted in your landscape’s sunniest, best-drained spot. It will not bloom profusely unless the plant gets plenty of sunlight.” You can’t be afraid to prune it either. Give the plant a haircut after the first exquisite flush of lavender blooms. Pruning encourages another round of flowers and keeps the plant from getting lanky and unkempt-looking. This perennial grows about 1 foot tall.

Dwarf Mexican Petunia

Zones 8 to 11

Trumpet-shaped, violet-blue flowers are born on the tips of the 1-foot stems and are extremely showy, partly because of the clouds of butterflies they attract. After the plant finishes flowering for the first time, cut it back about halfway to encourage another flush of blooms. Mexican petunia (Ruellia brittoniana) is adaptable and tolerates wet and dry soils. This perennial prefers full sun and will tolerate shade, but it will flower less in low-light situations. This dwarf variety grows less aggressively than the species and is an excellent choice for a long season of color.

‘Belinda’s Dream’ Rose

Zones 5 to 9

‘Belinda’s Dream’ was the first rose named a Texas Superstar. It was also the first rose to receive the prestigious Earth-Kind designation, meaning it’s been proven to be one of the best flowering roses requiring the least care. Earth-Kind’s tagline: If you can grow weeds, you can grow Earth-Kind roses. ‘Belinda’s Dream’ grows to about 4 feet tall and 3 feet wide. The fragrant pink blossoms are doubled, with a whopping petal count of more than 100. The blue-green foliage provides a lovely background for the delightful blooms.
