Calendula pot marigold

Height 30-60cm (1-2ft)

Planting distance 30-38cm (12-15in)

Flowers late spring till first frosts

Any well-drained garden

Hardy annual

The pot marigold is one of the easiest hardy annuals to grow and, with its glowing orange or yellow daisy-like flowers, one of the brightest. The flowers and light green lance-shaped leaves were formerly used in cookery, hence the name pot marigold.

Most varieties grow 45-60cm (18-24in) tall, and several 30cm (1 ft) high dwarf varieties are also available. Pot marigolds are excellent for growing in borders with poor soil. The long-stemmed varieties make good cut flowers and last well in water.

Cultivation

Pot marigolds thrive with little attention and in the poorest soil. For the best results, however, grow them in well-drained good garden soil.

Sow the seeds in their flowering site in early spring for summer flowering, or in early autumn foliate spring flowering. Cover with 1cm (1/2in) of soil. Thin out to 30-38cm (12-15in) apart. Dead-head to prolong the flowering season and prevent self-seeding.

Pests and diseases

Mildew and rust may develop on the leaves. In wet weather watch out for smut -dark irregular spots on the leaves. Caterpillars can be a nuisance.
