Our Plantsman's 6 plant collection includes, Eryngium eburnium, Eryngium yuccifolium, Eryngium bourgatii Picos Amethyst, Eryngium bourgatii Picos Blue, Eryngium agavifolium, and Eryngium ebracteatum poterioides. Plants supplied in 9cm pots.

 

Eryngium, or Sea Holly are some of the most desirable of ornamental perennial plants. Some of the species like bourgatii are colourful with their spiky blue bracts, whilst others are more architectural and statuesque such as eburnium and agavifolium. All have remarkable foliage, regardless of their flower colour. Our collection tries to give you a small taste of all these assets and the numerous species and hybrids now available.

There are about 220 species and their generic name derives from the Greek for sea holly - eryngion. Despite their thistle-like appearance they are Umbellifers - members of the carrot family. Each individual floret is rich in nectar so the prickly flowers are very popular with bees.

Eryngium agavifolium

Eryngium agavifolium is a handsome and striking evergreen architectural perennial with rosettes of sword shaped, sharply toothed, rich green leaves. Flower heads are thistle like, with greenish-white flowers on branched stems produced during late summer. Prefers full sun with dry, well drained soil and good drainage during the winter months. Hardy. Height 1.5m, spread 1m.

This outstanding variety has large true blue flowers in typical sea holly style. The showy parts of the flower of Eryngium bourgatii Picos Blue are in fact foliar bracts and start appearing in early summer, opening a ghostly silver and turning blue during the summer and autumn.
