Growth form
The clump-forming, shrub-like perennial develops an extensive root system with large tubers. It grows up to 100 cm tall and has egg-shaped, apple-green, felty leaves.
blossom
The flowering period of the burnet is in June and July. The whorls of yellow labiate flowers are arranged in "tiers" on the upright stems, one above the other. Their shape is reminiscent of dead nettles.
Location requirements
Burnet prefers a sunny to partially shaded location in moderately fertile, not too moist, and permeable soil. Six plants are needed per square meter.
Care
The plant is undemanding and easy to care for. The stems with the fruit clusters, like the leaves, remain standing and retain their green color well into winter. The wilted foliage and dry flower stems can then be cut back in early spring. Burnet also tolerates occasional dry periods. However, because it is a rather vigorous plant that reproduces by self-seeding, controlled pruning is recommended.
Other species and recommended varieties
Tuber burnweed (Phlomis tuberosa)
It has purple stems bearing lilac-pink, white-banded flowers. The leaves of the bulbous burnet are gray-green. Otherwise, it is very similar to its sister in structure, shape, requirements, and characteristics.
