Cuphea seeds usually take about 10 days to germinate. They should be grown for a further ten week,s then transplanted outdoors in the middle to late spring with a spacing of 25 to 30 cm (10 to 12 inches).

They prefer to grow in a partially shaded or sunny part of the garden that has a heavy soil that rich in humus.

Caring for Cuphea species such as Cigar plants in the Garden

Once the cigar plants have settled they should be pinched back at the growing tips, this will promote branching of the plant and lead to more flowers.

If you require more cigar plants then cuttings from the roots can be taken in the autumn.

Alternatively the plant can be grown as a perennial by over wintering the plants indoors.
