Salpiglossis Growing Guide

Salpiglossis sinuata

Salpiglossis

Crop Rotation Group

Solanaceae (Potato and tomato family) ●

Soil

Fertile, well-drained soil that holds moisture well.

Position

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.

Feeding

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.

Companions

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

Spacing

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 personalised calendar of when to sow, plant and harvest for your area.

Notes

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.

Harvesting

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

Troubleshooting

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