How to Grow California Fuchsia and other Zauschneria Plants

When growing California Fuchsia and related species from seed it is best to start them off outdoors. Sow the seeds in the springtime on the surface.

Zauschneria plants should be spaced at about 40 to 50 cm (16 to 20 inches) apart

They are able to grow in either a sunny or partially shady part of the garden.

It is important that the plant grow in soils that have good drainage; a slightly alkaline to neutral pH of 7 to 8 should give best results.

They usually take one or two months to germinate at a temperature of 15 to 18 degrees centigrade (59 to 64°F) in the light.
