Cultivation Details
The range of Grona styracifolia extends from southeastern China (hardiness zone 8 in Anhui and Hubei) to the tropical regions of southeast Asia. Plants from the north of its range experience light to occasionally moderate frosts and can be expected to succeed outdoors in the warmer regions of the temperate zone. Requires a well-drained soil and a sunny sheltered position[1]. Succeeds in full sunlight as well as in shade[2]. Because of the abundant small uncinate hairs on most species, the seedpods cling most tenaciously to clothing, to any part of the human body, and also to the feathers and hair of various animals, thus ensuring a wide dispersal of the plants[3]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[4].
Propagation
Seed - best sown as soon as it is ripe in a greenhouse. Scarify and pre-soak stored seed for 5 hours in warm water then sow early spring in a greenhouse. The seed usually germinates within 1 - 4 months at 25°c. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in the greenhouse for their first winter. Plant them out in late spring or early summer and consider giving them some protection from frost in their first winter outdoors. Cuttings of half-ripe wood with a heel, mid summer in a frame. Division as the plant comes into growth in the spring. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring. Root cuttings in winter. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Grona+styracifolia>
