Datura quercifolia
Datura quercifolia
Safety & Hazards
All members of this genus contain narcotics and are very poisonous, even in small doses[1]. All parts of the plant are poisonous, containing various alkaloids, notably atropine (daturine).
Cultivation Details
Datura quercifolia is not hardy in the colder areas of the temperate zone, it tolerates temperatures down to between -5 and -10°c[1]. Prefers a rich light sandy soil[2] and an open sunny position[1]. Grows best in a fertile calcareous soil[1]. This species is closely related to Datura stramonium[1].
Propagation
Sow the seed in individual pots in early spring in a greenhouse[1]. Put 3 or 4 seeds in each pot and thin if necessary to the best plant. The seed usually germinates in 3 - 6 weeks at 15°c. Plant out in late spring or early summer, after the last expected frosts. Especially in areas with hot summers, it is worthwhile trying a sowing outdoors in situ in mid to late spring.
