Salpiglossis Growing Guide

Salpiglossis, also known as Painted Tongue

Crop Rotation Group



Fertile, well-drained soil that holds moisture well.


Full sun to partial afternoon shade in warm areas.

Frost tolerant

Very slight. Established plants in a sheltered location can sometimes survive winter in milder areas.


Mix a standard application of a balanced organic fertiliser into the soil prior to planting. In midsummer, drench plants with a liquid plant food to stimulate new growth.


Showy salpiglossis blossoms look even better when the plants are framed with fine-textured flowers like frothy white sweet alyssum or dainty blue lobelia.


Single Plants: 30cm (11") each way (minimum)
Rows: 30cm (11") with 30cm (11") row gap (minimum)

Sow and Plant

Sow seeds in warm, moist seed starting mix, in early spring, or start with purchased plants. Seedlings grow slowly at first, so be patient.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.


Salpiglossis stems are not very stiff, so the plants often benefit from staking. Most varieties produce intricately veined, bicoloured flowers. A mixture of colours is fun to grow and lets you experiment with this comely flower.


Snip off spent blossoms to keep plants looking neat, and to prolong flowering.


Salpiglossis does not do well in very hot, humid weather. It grows best in areas with cool nights.
