Zinnia acerosa is found in the warm temperate to subtropical zone of southwestern N. America, growing in semi-arid regions. It grows best in areas with long, hot, dry summers and is able to tolerate some frost in winter so long as it is not wet[
Requires a position in full sun, growing best in a deep, rich, loamy, well-drained soil[
]. Grows well in calcareous or alkaline soils with a high pH and tolerates some shade in hot, dry environments[
The plant is antirheumatic - a crushed paste of the plant, mixed with salt, is used to alleviate swelling or aches[
The plant may be used within its native range in restoration of disturbed areas, wildlife and pollinator habitat improvement, and to increase plant diversity on adapted areas[
Seed - sow in containers in a greenhouse. Prick out into individual containers when the seedlings are large enough to handle and plant out when large enough[
]. In areas near the limits of the plants hardiness it would be better to keep the plants in pots in a sheltered position for their first winter, planting out in late spring.
