Texas Native Plants and Gardening:  Agave

There are more than 150 varieties of agave.

Agave is a bold, sculptural plant known for its dramatic rosettes, drought tolerance, and architectural beauty. Native to arid regions of the Americas, agaves thrive in Texas landscapes, particularly in dry, rocky soils and full sun. Their striking form and low water needs make them ideal for xeriscaping, modern design, and wildlife-friendly gardens.

Agave and the prickly pear have a photosynthesis ability that allows them to flourish in semiarid environments like many parts of Texas.

Crassulacean acid metabolism, the CAM process is the basis of a study to transfer their photosynthetic pathway to other plants.

I Call the Agave the Genius Plant because They Are SO Smart

 CAM plants absorb their CO2 at night rather than the day like most plants meaning there is less evaporation requiring between a fifth and a third of the water that other plants require.  They must store carbon overnight.  They still use their build sugar and starch energy reserves which require the sun!  The sun is their fuel, too.
Agaves fix their carbon in a transient pool of malic acid.   The sun breaks down these acids and then viola, release the C02.  Their stomata are not required to remain open because carbon is already in their leaf.
The Agave Plant comes in many shapes, sizes and colors, including variegated.  In landscaping, like painting, the golden triangle is effective.  Below you see yuccas and three kinds of agaves located at the Dallas Arboretum.

Agave Century Plant in Texas
The Agave plant is native to Texas and the southwest.  It is a succulent and not a cacti, though it shares many characteristics with cacti.  As a succulent, the agave stores water in its leaves.  There are between 100 and 200 species of the Agave with “The Century Plant” being the best known.  The Agave is related to the aloe plant.  Many agave flower once every ten years.  The tall flower grows from the center of the agave bearing tubular flowers. After development of fruit, the original plant dies with new plants produced from the base of the stem.

several agave species popular in Texas gardens have received prestigious horticultural awards, notably the Royal Horticultural Society’s (RHS) Award of Garden Merit (AGM). This award signifies a plant’s excellent performance, ornamental value, and ease of cultivation.CALS Communications

Tequila is made from the Agave plant.  All 100% blue agave tequila must be made from the Weber blue agave plant, to rigorous specifications and only in certain Mexican states.  This is similar to the requirement that Bourbon be distilled in Bourbon County, Kentucky.  The Agave is not a full sun lover.  It actually does best with filtered sun or just a tiny bit of shade.  Water your agave once every 4 – 5 days for for the first season as it become established and once a day in dry times for the first two months.  Once established the agave can be watered once every ten days to two weeks if there is no rain.  The plant is shallow rooted so watering with a soaker hose works very well.

The agave has two growing seasons, spring and fall.  While it will benefit from a 20-20 fertilizer during these seasons that will also encourage flowering, which will signal death for the plant.

1) Crown rot is a fungus that is present and become threatening with high moisture.  A preventative fungicide will address this issue.

2)  Snout weevils are a beetle that law their eggs between the leaves.  Mites can also be a problem.  These are addressed with an insecticide.  If untreated these can kill an agave.

The juice from many species of agave can cause skin blistering lasting one to two weeks.  If the skin is pierced deeply enough by the needle-like ends of the leaf from a vigorously growing plant blood vessels in the surrounding area can erupt.  It is for this reason the agave plant is considered to be potentially poisonous.

Texas Native Plants Agave General Characteristics

  • Foliage: Thick, fleshy leaves arranged in a symmetrical rosette; color ranges from silvery blue to dark green

  • Growth Habit: Varies from compact and low-growing to large and expansive; most varieties are slow-growing

  • Maintenance: Extremely low once established; most agaves are monocarpic (they flower once at maturity, then die), but may produce pups (offsets)


Popular Agave Varieties for Texas

  1. Agave americana (Century Plant)
    Large and dramatic; blue-gray leaves with spines
    Grows 6–10 feet wide and tall; suitable for open spaces

  2. Agave parryi (Parry’s Agave)
    Compact, cold-hardy variety with powdery blue leaves and decorative spines
    Grows 2–3 feet tall and wide; ideal for Central and North Texas

  3. Agave ovatifolia (Whale’s Tongue Agave)
    Broad, cupped blue-gray leaves with a stately presence
    Grows 4–6 feet wide and tall; excellent for focal planting

Recognition by Texas A&M

While agaves are not listed as Texas Superstars by Texas A&M AgriLife, they are widely recommended by Texas horticultural experts and extension programs for use in drought-tolerant and water-wise gardens. Their resilience, bold form, and low maintenance needs make them a smart choice for sustainable landscapes throughout the state.


Landscape Use

  • Focal points or specimen plants in rock or desert-style gardens

  • Xeriscapes and low-water-use gardens

  • Accent plants in contemporary, minimalist, or architectural designs

  • Container planting for patios and entryways

  • Wildlife habitat: some varieties attract hummingbirds when in bloom

Agave adds striking form and texture to any Texas landscape. Their low water use, bold silhouette, and adaptability to poor soils make them a practical and beautiful choice for long-term success in dry, sunny locations. With thoughtful placement and proper drainage, agave can thrive for decades and anchor any garden design.

1. Q: Is red yucca native to Texas and suitable for all regions?
A: Yes. Red yucca (Hesperaloe parviflora) is native to Texas and thrives across the state, from arid West Texas to humid East Texas, as long as the soil drains well. It tolerates extreme heat, drought, and alkaline soil.


2. Q: What is the difference between red, yellow, and scarlet yucca?
A: All are cultivars or color variants of Hesperaloe parviflora. Red and scarlet yucca are the same plant—“scarlet” simply describes the flower color. Yellow yucca is a cultivated form that produces yellow blooms but has the same size and shape.


3. Q: When does red or yellow yucca bloom in Texas?
A: These plants bloom from late spring through summer, often reblooming in early fall. Flower spikes appear after warm weather begins and may last several weeks, especially after rainfall.


4. Q: Does red yucca have any formal awards or recognition?
A: Yes. Red yucca was named a Texas Superstar® by Texas A&M AgriLife Extension in 2022, due to its consistent statewide performance with minimal maintenance. Yellow yucca has not received formal awards but performs similarly.


5. Q: What are the most common problems when growing yucca in Texas?
A: The biggest issue is overwatering or planting in poorly drained soil, which can lead to root rot. These plants are nearly pest-free and disease-resistant if grown in full sun with excellent drainage.

Devils Claw

 

Devil's Claw

Devil’s Claw for the most arid of climates.

Do you know about Devil’s Claw?  It grows in the hottest, driest parts of Africa.

Devil’s claw—a plant named for its spiky, fist-like seed pods—has been used by the Khwe people of southern central Africa for as long as anyone can remember. Its relative abundance in Namibia’s Bwabwata National Park is precious—as is the organic, sustainable harvesting business the Khwe people are now building around devil’s claw. It’s a business where women are the main farmers and the main beneficiaries.
