Kehäkukka

Kehäkukka (Calendula officinalis), commonly known as the pot marigold, is an annual herb in the aster family (Asteraceae). It is cultivated for its bright yellow to orange flower heads, which bloom from late spring to autumn and attract pollinators. The plant typically reaches 30–60 cm in height, with oblong, aromatic leaves and branched stems. The flower heads consist of ray florets arranged around a small central disc.

Originating from southern Europe and the Mediterranean region, kehäkukka is now grown worldwide as an ornamental plant and for traditional herbal uses. It thrives in full sun and well-drained soil, tolerates poorer soils, and is relatively drought-tolerant once established. It is commonly grown from seeds sown in spring; many varieties exist, including simple single and double blossoms in shades of yellow, orange, and orange-red. Deadheading encourages continued flowering.

In addition to ornamental value, calendula petals have been used in traditional herbal remedies and cosmetics. They are edible and sometimes used to garnish dishes. Scientific evidence on calendula’s medicinal effects is mixed; some studies suggest anti-inflammatory or wound-healing properties, but results are not definitive. People with sensitivities to Asteraceae or allergies should avoid use; consult a professional before using calendula on broken skin or during pregnancy.

In summary, kehäkukka is a widely cultivated, easy-to-grow ornamental with a long history in folk medicine and cosmetics, valued for its bright flowers and versatility in gardens and kitchens.
