Moisture retentive soil
Well drained soil
This is a stunning Eryngium with large silver bracts surrounding white thistle flowers in summer.
This Sea Holly has a slightly different inflorescence in that it is very spiny and it is silver while the thistle flower is cream.
Producing a cloud of blooms, each with a steely blue central cone encircled with pointed silvery bracts on blue multi-branched stems, its striking display lasts from mid to late summer.
This plant really lives up to its name, 'Big Blue', the intensity of blue on the large flower heads is stunning.
It forms good sized clumps in a reasonably fertile soil in full sun, and is great ...
A new and totally unique introduction of Sea Holly - the foliage of this Eryngium is a brilliant golden colour , it will become lime green if slightly shady. The flower spikes, stems and flower bracts
