EUPHORBIA (EXCALIBUR)

Image of Euphorbia 'Froeup' (EXCALIBUR)

Family

Euphorbiaceae

Botanical Name

EUPHORBIA 'Froeup'(EXCALIBUR)

Plant Common Name

Excalibur Spurge, Spurge

General Description

The new leaves of this striking hybrid spurge are tinted with red in spring, then change to rich blue-green, marked with a central line of ivory and thin, burgundy edges. Yellow tones develop with the cool temperatures of autumn. The lance-shaped leaves encircle thick, upright, pink stems which are topped with a display of brilliant yellow-green flowerheads in early to midsummer.

Provide 'Froeup' with full to part sun and well-drained soil of average to modest fertility. Wet, poorly-drained conditions should be avoided. If desired, stems may be cut to the ground after flowering to rejuvenate the foliage. This perennial is a terrific choice for rock gardens and well-drained mixed borders. This cultivar is sometimes sold under the name ‘Excalibur’.
