Goldentop grass (Lamarckia aurea): complete guide

Overview

Goldentop grass (Lamarckia aurea), also known as golden dogtail or golden-top, is an elegant annual grass distinguished by its characteristic golden, drooping plumes. Native to the Mediterranean region and North Africa, this grass brings exotic appeal to any garden. It grows to approximately 60 centimeters tall and forms a graceful, loose growth habit.

Appearance and bloom

The plumes of Goldentop grass are its most striking feature. These arch gracefully downward and develop a warm golden-brown hue throughout the summer. The fine, delicate foliage creates an airy silhouette that moves beautifully in gentle breezes. The grass flowers from June to September, attracting butterflies and bees.

Ideal location

Goldentop grass thrives in sunny locations receiving at least 6 hours of direct sunlight daily. While it tolerates partial shade, it produces more abundant plumes in full sun. Plant it where it can sway freely in the wind, allowing its elegant form to be fully appreciated.

Soil

This grass is not fussy and grows well in nearly any soil type. It prefers well-drained, slightly sandy soil but tolerates heavy clay quite well. Maintain a pH between 6.0 and 7.5. Loose, nutrient-rich soil promotes optimal growth.

Watering

Although Goldentop grass tolerates drought once established, it grows better with consistent moisture during its growing season. Water moderately during the main growing period, especially for young plants. Once matured, the plant requires minimal supplemental watering except during exceptionally dry spells.

Pruning and maintenance

Goldentop grass is an annual that is removed at season's end. It may self-seed in warm climates. Remove any damaged or malformed foliage as needed. Seeds are available at garden centers for replacements the following year.

Maintenance calendar

Sow Goldentop grass seeds in spring after the last frost (May). Summer is for growth and flowering. In August, collect seeds for next season. In October/November, remove spent plants.

Winter hardiness

Goldentop grass is not winter-hardy and grows only as an annual in temperate climates. Plant it after the last frost date. In warm regions (USDA zones 9-11), it may self-seed and reappear in subsequent years.

Companion planting

Goldentop grass combines beautifully with lavender, dahlias and purple sage. It forms striking contrast with large, structural plants such as agaves or phormium. Use it for movement in border arrangements or massed for dramatic impact.
