Description
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).
Habitat
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).
Threats
The threats facing this species are unknown.
Conservation
There are currently no conservation measures targeting this species.
