How To Grow Torenia or Wishbone Flower in The Shade Garden


Torenia or Wishbone Flower is a delightful small flowering shade to part shade annual (resembles a small pansy) that is perfect for container gardening.

A native of Vietnam it is well-adapted to heat and humidity. I used to grow several varieties at our nursery because it filled some special niches in container gardening and we loved it for it's small violet blue blossoms.

A fact you an use at cocktail parties is that the name comes from the two stamens coming out of each flower that are shaped into a "wishbone"

Torenia 'Grape o Licious'

I purchased the above, newer variety of Torenia in spring 2013 to run some container trials with it and you can see the link to reviews at the bottom of this page.

Considering the downy mildew problem with impatiens, I thought it was time to start testing alternatives.

Sowing Your Own Seed


Indoors


Sow seed into warm soil at 70F (21C) and if you don't use a heat mat, you're wasting your time. Should germinate in 10 days.

Cover as it prefers darkness and the way to do this is to firm the soil with your hand before sowing and dust the seed (they're fine) onto that firmed soil Then cover *very* lightly with other soil.

Once seedlings are germinated, give full sunlight and 70F day and 60F night temperatures. If you deviate on these temps, you may find the seedlings get leggy.

Outdoors


Sow outdoors as above (firm soil, press seed into it and cover lightly) Thin seedlings to 8-inches apart.

Sow some seed about 8 weeks before frost and dig them up to pot up for the house blooms.

New Varieties From Cuttings - are being produced by specialist propagators - only come true from cuttings. See review below for an example.

The fine print


Deer resistant and heat tolerant. Two perfect combinations! :-)

You don't have to deadhead and pick off the flowers as they are "self-cleaning".

This isn't a showy plant but a perfect small pot plant or addition to the container planting

Best growing tip: use in containers and don't be afraid to pinch off the growing tips to thicken up the growth.
