Expert tips
The key tip
Spigelia marilandica requires partial shade and consistent moisture; avoid drying out during growth. Rich, slightly acidic soil, mulched to retain freshness.
The common mistake
Placing it in full sun or dry soil: it yellows, won't flower, and declines quickly.
The pro's trick
Pair it with shade-loving plants (ferns, heucheras) to create a cooler, more humid microclimate.
Care
Light Exposure
Maryland spigelia appreciates partial shade and tolerates lightly shaded areas well. It can receive a few hours of morning sun, but dislikes intense afternoon sun exposure. Plant it under trees or near a structure that provides dappled light.
Watering
Keep the soil consistently moist without waterlogging. Water once or twice a week depending on weather conditions and soil type. During the growing season (spring-summer), increase watering frequency slightly. In winter, reduce watering as the plant goes dormant.
Soil
Choose rich, well-draining soil that is slightly acidic to neutral. Enrich the potting mix with compost or organic matter before planting. Overly compact or chalky soil may slow its growth.
Fertilizing
Apply balanced fertilizer in spring when active growth resumes. Monthly feeding during the growing season is sufficient. Avoid excess nitrogen, which would promote foliage at the expense of flowering.
Pruning and Cutting
Remove spent flowers regularly to extend the flowering period. In late winter or early spring, before growth restarts, you can prune lightly to maintain a compact shape. Also remove dead or damaged stems.
Diseases and Pests
Spigelia is generally robust and rarely affected by common pests. Monitor for excessive moisture, which can promote fungal diseases. Ensure good air circulation around the plant to prevent fungal problems.
Did you know?
Maryland spigelia has fascinated botanists since the 17th century in North America, where indigenous peoples traditionally used it for its properties. Its scientific name pays homage to its state of origin, while its bicolored red and yellow flower attracts hummingbirds and butterflies, making it an excellent plant for gardens welcoming wildlife.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
