Salpiglossis Growing Guide

Salpiglossis sinuata

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 climates.

Frost tolerant

Very slight. Established plants in a sheltered location can sometimes survive winter in mild climates.

Feeding

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

Spacing

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

Notes

Salpiglossis stems are not very stiff, so the plants often benefit from staking. Most varieties produce intricately veined, bicolored flowers. A mixture of colors 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.
