From late spring through to late summer (May to August), this plant produces abundant, trumpet-shaped flowers that are a deep, rich red with a velvety texture. Each flower is approximately 3–5 cm (1–2 inches) across, with a flared, five-lobed corolla. The striking colour and unusual form of the flowers make ‘Red Emperor’ a standout feature in any moist garden setting.

Growing Conditions

Mimulus cupreus ‘Red Emperor’ thrives in full sun to partial shade and requires consistently moist or waterlogged soil to perform at its best.

Slightly acidic to neutral soils are preferred.

Hardy in the UK, this cultivar can tolerate mild frosts, but in colder regions, it may benefit from mulching or protection during the winter months.

Propagation and Care

Mimulus cupreus ‘Red Emperor’ is propagated by division, cuttings, or seed. Division is typically done in spring or early autumn by carefully separating clumps and replanting them in moist soil. Softwood cuttings taken in early summer root easily in damp conditions. Seeds can also be sown in spring in a consistently moist seedbed or container.

Once established, this plant requires minimal care. Regular watering is essential to maintain the damp conditions it thrives in. Deadheading spent flowers encourages prolonged blooming and helps keep the plant looking tidy. If grown in containers, ensure consistent watering to prevent the soil from drying out.
