The family Umbelliferae, to which this species belongs, is so named for its characteristic umbels, umbrella-shaped flower clusters in which all the flower stalks radiate from the same point, appearing as if a single flower head (3). The flowers of this thistle-like Eryngium species are densely clustered into tight dome-shaped umbels and surrounded by a collar of spiky bracts (4). The small heads, or umbels, of this plant are a green to metallic blue colour (5).

Eryngium biology

This Eryngium is a deciduous perennial (2) that blossoms from July to August (5). The flowers contain both male and female reproductive organs and are pollinated by a wide variety of insects, including bees, flies and beetles (6). This plant is self-fertile, meaning that it can produce seeds through fertilisation with its own pollen, without other plants being needed (6).
