Castanea pumila ashei
Chinquapin
Taxonomy and growth
Uses
Edible uses
Seed - raw or cooked[7][14][2]. Sweet with a nice nutty flavour[13][16][6], it is very acceptable raw[142, 161, K]. When baked it becomes even sweeter and develops a floury texture, it makes an excellent potato or cereal substitute[K]. The seed is quite small, about half the size of C. dentata[6]. Sold in local markets in America[16].

Medicinal uses
Historical medicinal uses. These records describe reported uses. They do not establish safety or effectiveness. Ask a qualified health professional before using any plant medicinally.
The leaves contain tannin and are antiperiodic, astringent and tonic[13][14][9]. An infusion of the leaves has been used as an external wash for the feverish condition common to colds[9][11].

Propagation
Seed - where possible sow the seed as soon as it is ripe in a cold frame or in a seed bed outdoors[15]. The seed must be protected from mice and squirrels. The seed has a short viability and must not be allowed to become dry. It can be stored in a cool place, such as the salad compartment of a fridge, for a few months if it is kept moist, but check regularly for signs of germination. The seed should germinate in late winter or early spring. If sown in an outdoor seedbed, the plants can be left in situ for 1 - 2 years before planting them out in their permanent positions. If grown in pots, the plants can be put out into their permanent positions in the summer or autumn, making sure to give them some protection from the cold in their first winter[K]. Division of suckers in winter[8]. They can be planted straight out into their permanent positions.
Cultivation
Prefers a good well-drained slightly acid loam but succeeds in dry soils[1][3][8]. Once established, it is very drought tolerant[1][3][8]. Very tolerant of highly acid, infertile dry sands[8]. Averse to calcareous soils but succeeds on harder limestones[3][8]. Although it is winter-hardy in most areas of Britain, this species only really thrives in areas with hot summers[8]. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[K]. Produces suckers, eventually forming a thicket[5]. An excellent soil-enriching understorey in pine forests[8]. Flowers are produced on wood of the current year's growth[10]. Plants are fairly self-sterile[8]. They hybridize freely with other members of this genus[8]. Fruits are produced within 2 - 3 years from seed[4]. One report dealing with the type species states that it never fruits in Britain[3]. However, a bush at Wisley fruits well in most years[K]. Therefore it is hoped that this sub-species will also fruit in Britain[K]. There are a few plants at Hilliers Arboretum, but we have never seen them produce fertilized fruits[K]. Plants in this genus are notably resistant to honey fungus[8].
