How to Grow and Care for Torenia (Wishbone) Flowers

Torenia Fournieri

If your shady spots are looking a little dull and uninspired, you may want to consider Torenia fourneiri, which blooms generously and brightly in shade.

Another mark in the “wow” column for this lovely annual comes from its velvety bicolored or tricolored trumpet-shaped flowers with their delicate throats of contrasting color.

The flowers are reminiscent of their cousins, snapdragon and foxglove. All three are members of the figwort (Scrophulariaceae) family.

Also known as wishbone flower, bluewings, and clown flower, this compact plant will grow in Zones 2-11.

Let’s learn more about this little cutie.

For the Birds

Native to Asia and Africa, this bushy plant grows seven to 12 inches tall and spreads six to eight inches. But it’s not aggressive or invasive, so there’s no need to fear a takeover.

Hummingbirds will enjoy torenia’s one- by one-and-a-half-inch flowers almost as much as you do, savoring their sweet nectar during the plant’s midsummer to mid-fall bloom period.

Its “wishbone flower” nickname comes from the two stamens that grow from opposite sides of the flower, meeting in the middle and forming a structure that resembles a chicken wishbone.

Its “clown flower” nickname comes from its colorful “face.” “Bluewing” is derived from its often blue, wing-shaped petals.

Good companion plantings for torenia include impatiens and ferns.

Outdoors and In

Low-growing torenia makes a lovely border or bedding plant that is glorious in containers, too. Some gardeners also grow it as a houseplant.

In the landscape, plant torenia in moist, rich soil in an area that is partly shady.

You can start seeds indoors six to eight weeks before the expected last frost, or sow seed directly in the garden just before the last frost date. Expect germination in 10 to 15 days at about 70°F.

You’ll want to apply a one-inch layer of mulch after seedlings emerge or after transplanting.

Pinch for Bushiness

Keep the soil moist but not soggy, as these plants are susceptible to root rot and powdery mildew. You may treat the latter with a fungicide, such as this one from Garden Safe, available via Amazon.

Water bluewings regularly, especially in hot weather, and be thankful that these plants have no serious insect or disease problems.

Fertilize wishbone plants once or twice a month with a plant food that is high in phosphorus, and be sure to water the plants thoroughly before and after fertilizing to avoid root burn.

It’s not necessary to deadhead the flowers. In fact, some gardeners find the seed heads quite attractive.

When the young plants are about three inches tall, you’ll want to pinch back the growing tips of the plants to encourage branched growth and an attractive bushy shape.

Happier than a Clown

You’re sure to be cheered each time you see these clown-faced flowers smiling at you from the depths of the shady spots of your garden.

She’s never met a succulent she didn’t like and gets really irritated every 3-4 years when Austin actually has a freeze cold enough to kill them. To Gretchen, nothing is more rewarding than a quick dash to the garden to pluck herbs to season the evening meal. And it’s definitely time for a happy dance when she’s able to beat the squirrels to the peaches, figs, or loquats.
