Eryngium planum 'Blue Cap'

Sea hollies look very exotic in floral arrangements. Something about them seems like they'd be hard to grow, but they've been super easy to cultivate in our garden! All they need to thrive are lots of sunlight and well-drained garden soil.

The icy blue coloration runs not only through the flowers but also through the bracts and down the stems. They contrast well with other cottage flowers in pink and apricot shades; our favorite pairing is 'Blue Cap' sea holly and 'Summer Pastels' yarrow.
