Euphorbia ‘Excalibur’ is a variety selected for its glorious red coloured spring foliage and shoots followed by long lasting yellow summer inflorescence. This variety proved to be very hardy and reliable clump-forming perennial. Height 80cm. Spread 50cm.

Euphorbia ‘Excalibur’ was selected and named on our nurseries as distinct form from a batch of seedlings which were originally named E. jacquemontii. It is still not certain that ‘Excalibur’ belongs to this Himalayan species, and indeed Kew believes it to belong to E. longifolia. This group of the Euphorbia seems to be in constant debate and so it is best classified just as Excalibur. It has a similar growth habit to either E. schillingii or E. longifolia but has rich vinous purple/red stems and rich red tinted young foliage. The young stems to some extent resemble E. sikkimensis when the new shoots first emerge from the soil in early spring, but unlike that species which has an aggressive running habit, Excalibur forms a tight clump of stems.
The flowers appear during late summer and are typical of this group with their pale yellow bracts. The adult foliage retains some of the early bright colour suffused within the glaucous grey/green leaves with their typical white central mid-rib.
During the autumn and winter the tall flowering stems turn a glorious red, similar to that of some of the best forms of Cornus alba.
