Members of the Torenia genus are usually grown as half hardy annuals in gardens and they reach about 30cm in height.

How to grow Wishbone Flower

If growing Wishbone flowers outdoors from seed then sow on the soil surface in spring, a week or so after the last chance of frost. Wishbone flowers (and other Torenia species) should be spaced about 15 to 20cm apart and grown in a sunny area that is shaded in the afternoon. Ideally the soil that Wishbone flowers grow in will have good drainage, be moist, and should be enriched with organic matter.

If planning to start off indoors then sow wishbone flower seed about 8 weeks before due to be transplanted outdoors. It should take from one to four weeks for the seeds to germinate at 20 to 23 degrees centigrade in the light. Once established transplant into the garden a couple of weeks after the last chance of a frost.

Caring for Wishbone flowers

Plants such as wishbone flower and bluewings are pretty easy to look after; once they have been growing for a few weeks and reached an height of about 8cm pinch them back; this will encourage branching and result in a bush and healthy looking plant. As they like moist soil it is necessary to water wishbone flowers on a regular basis. If you require more plants then they can be sown from seed or cuttings took.
