Sombrero Blanco Coneflower

Echinacea 'Sombrero Blanco'

The Story

Plant Bio

Echinacea, or coneflowers, are upright, daisy-like perennials native to North American prairies. They are renowned for their long bloom season, drought tolerance, and attractiveness to pollinators.

'Sombrero Blanco' is a compact, sturdy, and well-branched cultivar that produces a profusion of large, pure white, single flowers with a prominent golden-brown central cone.

Uses & Benefits:

Its clean white flowers provide a bright, refreshing look in the summer garden, blooming for months. The sturdy stems make it an excellent, long-lasting cut flower for arrangements.

This coneflower is drought-tolerant once established, making it a great choice for low-water gardens and sunny, hot locations. It is also reliably deer resistant.

Echinacea is a powerhouse for pollinators, attracting a wide array of bees, butterflies, and even hummingbirds. In the fall and winter, its seed heads provide a vital food source for finches and other seed-eating birds.

How to Grow

Select a site that receives at least 6 hours of full sun per day.
Ensure the soil is well-drained; amend with compost if needed.
Dig a hole as deep and twice as wide as the container.
Place the plant in the hole with the crown at soil level.
Backfill with soil, firming it gently around the plant.
Water thoroughly after planting and regularly during the first season.

Pro Tip

Avoid rich soil and heavy fertilization, which can lead to weak, floppy stems and reduced lifespan.

Care Guide

Do

Provide full sun for the strongest stems and most prolific blooms.
Allow the soil to dry out between waterings once established.
Deadhead regularly to promote reblooming.
Leave seed heads on in the fall for birds like goldfinches.

Don't

Do not plant in wet, poorly drained soil, especially in winter.
Avoid over-fertilizing, which can make plants leggy.
Don't overcrowd plants; provide good air circulation to prevent disease.
Refrain from heavy mulching in winter, which can trap moisture and cause rot.
