Calendula

Calendula officinalis

Orange and golden daisy-like flowers brighten a leafy, branching plant.

Make it part of your growing collection.

A LITTLE EVERYDAY CARE

Help it thrive.

A few things worth knowing.
01

Choose freely draining soil

Use a light soil in sun or partial shade; rich ground is unnecessary.

02

Remove spent blooms

Regular deadheading encourages more flowers.

03

Pinch for branching

Pinch out shoot tips to encourage a bushier plant.

Data sources & uncertainty
Sunlight

Sun and some shade are described; 2+ hours is a broad category, not a yield guarantee.

Moisture

Drought resistance and free-draining cultivation support a broad drier-to-moderate interpretation, not a watering schedule.

Source · checked 2026-09-20
Soil pH

No precise preferred numeric interval verified; the unused placeholder is excluded from display and scoring.

Source · checked 2026-09-20
Drainage

Free drainage is recommended; the ordinal interval is an interpretation, not a measured drainage rate.

Soil texture

Listed textures are examples, not an exhaustive tolerance list.

Plant spacing

30 cm is a cultivar-dependent allowance within the listed 10–50 cm spread, not a universal planting distance.

Source · checked 2026-09-20
Growing depth

Approximate planning allowance, not a verified root depth; cultivar and growing method change the requirement.

Source · checked 2026-09-20
Typical height

Approximate planning height; cultivar, pruning and growth stage change the result.
