Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - best surface sown in a cold frame as soon as it is ripe. Stored seed should be soaked for 5 - 6 days in warm water and then surface sown in a shady position in a greenhouse[10]. Do not allow the compost to become dry. 6 weeks cold stratification helps[3]. The seed usually germinates well in 2 - 3 months at 20°c[3]. Seedlings are prone to damp off[6], they are best transplanted to individual pots as soon as they are large enough to handle and should be kept well ventilated. Grow them on in a greenhouse for their first winter and then plant out in late spring after the last expected frosts[K]. Basal cuttings in late winter[7]. Cuttings of mature wood of the current season's growth, November/December in a frame. Poor percentage[10]. Layering of young wood - can take 2 years[1][7].

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Requires a lime-free nutrient-rich well-drained moisture-retentive soil in sun or semi-shade and shelter from cold drying winds, especially when young[7]. Succeeds on dry soils[11]. This species is unlikely to be hardy in the colder areas of the country, it probably tolerates temperatures down to between -5 and -10°c[7]. There is some confusion over the name of this plant, some books suggest that A texana is a synonym of A xalapensis. HBK. whilst others say that A texana exists in its own right and has a synonym of A. xalapensis. non HBK[2][4][7]. A. texana is very closely related to A. xalapense and is considered by many botanists to be indistinguishable from that species[9].
