I am thinking about growing these plants from seeds. Any advice? I am sure I read somewhere to put the seeds in the fridge for 6 weeks?
In warm sunny climates this annual may be grown in partial shade. It will prefer full sun and loamy to sandy soil. You should transplant outdoors after the frost danger has passed. Watch out; it is poisonous.
Propagation is by seeds in the spring or by greenwood or semi-ripe cuttings in early summer.
Pests, diseases or disorders
Whitefly and red spider mite may be troublesome.
