Eryngium giganteum 'Miss Wilmott's Ghost' / Giant Sea Holly / Seeds

Miss Wilmott’s Ghost is a popular Victorian variety of Giant Sea Holly.  Plants have attractive silvery white flowers in June to August.  The spiky brachts and cones of tiny flowers make this a distinctive plant, looking best in sunny borders and especially good in gravel gardens. Plants grow to a height of 60-90cm. They make good fresh and dried cut flowers.


Giant Sea Holly prefers a sunny well drained position, and can tolerate drier soils and coastal sites.  It is a biennial plant, growing a rosette of leaves in the first year and then growing vertically and flowering in the second year.  It will self-seed.


Pack of 30 seeds.  Sow in autumn to early summer.   Germination is best with 3-6 weeks of chilling, either in a cold frame in winter or in a fridge.  Sowing instructions and a colour photo are printed on the packet.

Sow

Sow in autumn/winter on the surface of a tray of seed compost.  Cover with clear plastic/glass, and over-winter in a cold frame or unheated greenhouse.  Keep in the light.  Seedlings emerge in spring.  Or sow in spring/summer, and keep at 18-22°C for 2-4 weeks, move to a fridge for 3-6 weeks and then to 15-18°C, and germination starts in a few weeks.  Transplant seedlings into pots and into the garden after the last frost.  

Grow A rosette of leaves forms in the 1st year and flowering takes place in the 2nd year. Plants generally die back after flowering, although some may live in for a another year or two. Leave the flower stalks on the plants overwinter for an attractive display and to encourage plants to self-seed. Remove spent plants in autumn to spring.
