Crop Rotation Group

Miscellaneous ●

Soil

Fertile, well-drained soil.

Position

Full sun.

Frost tolerant

Can tolerate light frosts in warmer areas, where convolvulus can be grown as a short-lived perennial.

Feeding

Mix a light 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

Convolvulus can grow into somewhat floppy plants that benefit from close company with plants that produce lush foliage, such as parsley or ageratum.

Spacing

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

Sow and Plant

Soak the hard seeds in water overnight before planting indoors, and keep the seeded pots warm. In areas with long summers, convolvulus can be sown directly into beds after the last frost has passed.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

This flower is capable of blooming for six weeks in late summer. The plants look best when planted in groups. Colour options include blue, white, and pink.

Harvesting

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

Troubleshooting

This species can sometimes reseed, but the annual form (Convolvulus tricolour) is not invasive.
