Acer pentaphyllum Seeds | Five-lobed Maple
LATIN NAME: Acer pentaphyllum
COMMON NAME: Five-Lobed Maple
Plant Profile
Five-Lobed Maple (Acer pentaphyllum) is a rare deciduous tree of the soapberry family (Sapindaceae), restricted to a few valleys of western Sichuan, China. Uniquely among maples, its leaves are palmately compound with five narrow leaflets, turning rich red in autumn. Critically endangered in the wild, it survives in cultivation in a handful of botanic gardens and collections.
Science & Biotechnology
Research touching on Acer pentaphyllum ranges from the botany of the Acer group to practical horticulture, including seed handling, propagation and the selection of superior forms. Botanical gardens and seed banks worldwide hold accessions specifically to preserve its genetic diversity, and population genetic studies of remaining wild trees inform ongoing efforts to protect species from extinction. It is the kind of species that plant scientists reach for when they need reliable material for propagation and selection studies.
Uses & Benefits
Beyond its ornamental appeal, Five-Lobed Maple has the practical versatility that makes a plant worth growing from seed year after year. In wild, five-lobed maple anchors a narrow, ecologically fragile riverside habitat found nowhere else, making survival of intact wild stands itself the species’ most important value. In cultivation, growing this species from seed contributes directly and meaningfully to global conservation efforts by expanding small number of living, documented individuals held safely outside its vulnerable native range. After the first season it asks for very little beyond a place that suits it.
Maples give more than syrup and shade: the bark of several species appears in East Asian folk medicine for liver and eye comfort, and maple polyphenols, the glucitol-core gallotannins, are an active research area. Sugar maple’s mineral-rich sap remains one of the great wild tonics of the northern spring.
Growing from Seed
Starting Five-Lobed Maple from seed is simple and satisfying. Growing this species from seed is a genuinely meaningful conservation act given how few individuals remain in its native river valley. Broadcast the seed thinly over a fine, free-draining compost, sieve a little more compost on top, and water with a fine rose. Pot the young plants on as they grow, harden them off gradually, and plant them into their final positions when sturdy.
Our Take
Part of this plant’s appeal is the long practical history summarized above. Five-Lobed Maple is the kind of plant that rewards a permanent spot. Plant it in sun with drainage to its liking and the rest is easy.
