How to Grow Leptosyne gigantea

Overview

Giant coreopsis (Leptosyne gigantea) is a stunning woody perennial native to California's coastal regions and northern Baja California. With its bright yellow flowers that bloom from late spring to summer, this plant adds a pop of color to any garden while attracting pollinators like bees and butterflies.

Growing Conditions

Giant coreopsis thrives in full sun and well-drained soil. It is drought-tolerant once established but will flower more abundantly with regular watering. This hardy plant is resistant to deer, rabbits, and pests, making it a low-maintenance addition to your garden.

Planting & Care

Plant giant coreopsis in late fall or early spring for best results. Dig a hole deep enough to accommodate the plant's woody stem, as these plants can grow quite large over time. Water well after planting and provide occasional watering during dry spells. Prune back any dead foliage in late winter to encourage healthy new growth.

Common Problems

Giant coreopsis is generally disease- and pest-resistant, making it a low-maintenance choice for your garden. The main issue you may encounter is poor flowering due to insufficient sunlight or water. Ensure the plant receives at least 6 hours of direct sun each day and water regularly during dry periods.

Harvest or Enjoy

While giant coreopsis is not typically harvested for use in cooking, it provides plenty of enjoyment in your garden. Sit back and enjoy watching the pollinators visit its vibrant blooms throughout spring and summer. You can also propagate new plants from cuttings taken from healthy, mature stems.
