Scarlet Globemallow

Also known as: Orange Globemallow, Copper Mallow

This perennial plant, known as the scarlet Globemallow (Sphaeralcea coccinea), is native to much of the western United States and was the last plant collected on the Lewis and Clark expedition. It grows via spreading rhizomes, enjoys growing in open prairies, and has been used in reclamation plantings to reintroduce native plants to fields overrun by invasives.

Growth Rate

Scarlet Globemallow's rapid growth rate is prominently seen during spring and summer. Age syncing with the warmer months fuels an accelerated production of foliage and significant height increase. Rising temperatures encourage peak expression, enabling prolific flowering. Rapid growth, however, may necessitate closer nutrient management.

Water: Well-suited for arid regions, scarlet Globemallow thrives with minimal watering, requiring weekly hydration to prevent over-saturation. It prefers a dry climate and benefits from well-draining soil that mimics its native sandy habitat, ensuring optimal water retention while avoiding root rot.

Fertilize: For optimal growth, scarlet Globemallow requires a balanced fertilizer, such as 10-10-10, applied sparingly in spring. Limit feeding to once a year to avoid over-fertilization. Seasonal growth varies; during dormancy in winter, reduce feeding. Apply fertilizer away from the stem and water the soil first.

Pruning: Scarlet Globemallow features vibrant red-orange flowers and is drought tolerant. Prune in early to late spring to enhance growth, remove dead stems, and shape the plant. Regular pruning boosts flowering and airflow, reducing disease risk. Consult local resources for tailored plant care guidance.

Propagation: Scarlet Globemallow is a perennial herb that prefers well-drained soils and full sunlight. Propagation involves taking semi-ripe cuttings during active growth, placed in a suitable rooting medium with controlled moisture and light. Providing bottom heat aids rooting before transferring to larger pots or garden positions.
