Chocolate flower (Berlandiera lyrata)
Discover Berlandiera lyrata, the Chocolate flower—a drought-tolerant, low-maintenance perennial with fragrant yellow blooms.
Complete Plant Information
Overview
The Berlandiera lyrata, widely known and loved as the Chocolate flower, offers gardeners a unique textural and aromatic addition to dry, sunny locations. This herbaceous perennial is prized for its daisy-like flowers that emit a distinct chocolate scent, particularly noticeable in the morning. Its robust nature and native origins in the dry landscapes of the Southern US make it an exceptional choice for sustainable gardening.
As a member of the Asteraceae family, this plant features bright yellow rays contrasting with maroon-brown centers, blooming profusely from late spring until the first hard frost. The Chocolate flower establishes a long taproot early in its life cycle, which contributes significantly to its remarkable drought tolerance once established.
Functionally, Berlandiera lyrata requires minimal effort, fitting seamlessly into low-maintenance landscapes or wildflower meadows. Its ability to thrive where many others struggle makes the Lyreleaf greeneyes a reliable performer in hot, arid spots.

How to Grow
Plant the Chocolate flower in early spring or fall into locations receiving consistent full sun exposure. This perennial prefers average, well-drained soils and shows excellent tolerance for dry, shallow, or rocky conditions, leaning towards slightly alkaline pH. Avoid heavy, constantly wet soils, as the primary threat to Berlandiera lyrata is root rot in overly moist conditions.
Maintenance remains commendably low for this western native. While it tolerates dryness well, providing consistent moisture can increase overall flower production, though caretakers should be mindful that excess water frequently leads to stem drooping. Fertilization is rarely necessary; focus instead on pulling up spent flower stems if a tidier appearance is desired, but allow some self-seeding if you wish to expand patches naturally.
Due to its critical long taproot—the source of its drought stamina—division of established Berlandiera lyrata clumps is strongly discouraged and seldom successful. Propagation is best achieved by sowing seeds directly into the garden bed.
Landscape Uses
The recommended uses for this plant are broad, leaning heavily toward naturalized or informal settings. If you are developing a wildflower meadow or wish to add texture to a sunny roadside bank, the spreading habit and low water needs of the Chocolate flower are ideal. It excels as a lower edging plant in perennial borders where heat is intense and water conservation is a goal.
Consider using Berlandiera lyrata alongside other tough, sun-loving western natives such as various Penstemons or Rudbeckias. Its 1-2 foot stature keeps sight lines clear, making it an excellent choice for the front layer of a mixed sunny border where informal structure is desired. Its low maintenance profile also suits rock gardens beautifully, particularly where drainage is naturally sharp.

Noteworthy Characteristics
Berlandiera lyrata, commonly called chocolate flower (also known as lyreleaf green eyes) is native to dry sandy loams, rocky limestone soils, mesas, plains, grasslands and roadsides in Colorado, Kansas, Oklahoma, Arizona, New Mexico, Texas and Mexico. It typically grows to 1-2’ tall on branched, usually erect but sometimes decumbent stems, and features aromatic, night blooming, daisy-like flowers (1-2” diameter) with yellow rays, maroon-brown center discs and green cup-like bracts. Flowers bloom at night from late spring to frost, but in frost free areas will bloom year round; the aroma is strongest in the early morning before the petals close.
Tolerances
- Drought
- Dry Soil
- Shallow-Rocky Soil
Potential Problems
The Chocolate flower enjoys excellent pest resistance, with no serious insect or disease issues typically reported when grown correctly. The major cultural issue to avoid is excessive moisture, especially in spring, which invites root rot. Deer actively avoid browsing on established plants due to defensive compounds in the foliage. In extremely wet conditions, stems may sprawl, necessitating staking or placement in drier areas to maintain an upright habit.
Frequently Asked Questions
What hardiness zones is Chocolate flower suitable for?
Berlandiera lyrata is reliably hardy in USDA Zones 4 through 10, offering wide adaptability across the continental US.
How large does Berlandiera lyrata grow?
This plant typically reaches a mature height and spread between 1 and 2 feet tall and wide.

Conclusion
The Berlandiera lyrata, or Chocolate flower, is an outstanding selection for gardeners prioritizing drought tolerance, low maintenance, and unique evening fragrance. Its ability to thrive in poor, dry soils ensures reliability where manicured lawns cease. Before planting, confirm that your site offers full sun and excellent drainage to best enjoy this resilient native centerpiece.
Companion Planting
When integrating Berlandiera lyrata into your garden design, select companions that share similar needs for sun and dryness. Grouping it with other Mediterranean or prairie natives ensures that maintenance routines—especially watering—remain consistent for the entire grouping. Good partners include various drought-resistant Salvias, Russian Sage (Perovskia atriplicifolia), and other hardy Coneflowers (Echinacea species), which value sharp drainage as much as the Chocolate flower does.
Wildlife Benefits
Although often overlooked in favor of more colorful blooms, the fragrant, night-opening nature of the Berlandiera lyrata flowers makes it valuable for nocturnal pollinators. While the daytime yellow rays attract general garden bees, the strong chocolate scent is likely utilized by moths seeking nighttime nectar sources. Furthermore, its naturalized growing habit provides ground cover and structure beneficial to ground-dwelling beneficial insects in sunny, dry meadows.
