Ceratostigma plumbaginoides
Bunge[1]

Growing to 50 cm (20 in) tall and broad, it is a mat-forming herbaceous perennial with small ovoid leaves and bright blue flowers in late summer and early autumn. The leaves may turn red or purple before falling.

The Latin specific epithet plumbaginoides signifies its resemblance to plants in the closely related genus Plumbago.[3]

Ceratostigma plumbaginoides is grown as an ornamental plant in temperate climates, valued for its late season colour. It is hardy down to −10 °C (14 °F), but prefers a sunny, sheltered position in moist, well-drained soil. As it can become invasive, it is particularly suited to growing in a pot, or crevices in a dry stone wall.[4] It has gained the Royal Horticultural Society’s Award of Garden Merit.[5][6]

Etymology

Ceratostigma is derived from Greek, meaning 'horned stigma’. This is in reference to the ‘shape of the stigmatic surface’.[7]

gollark: They probably can't/won't eternally torture you, but there's a *possibility* of that infinite harm which is reduced by giving them £100, and if you accept the Pascal's Wager logic you should do that.
gollark: There's actually another similar thing, Pascal's *Mugging*, in which someone comes up to you and says "give me £100 or I will eternally torture you after you die".
gollark: But there are an infinitely large number of possible gods, and some do weirder things like "punish/reward entirely at random", "have no interest whatsoever in humanity", "punish people who believe in other gods", and all that, and Pascal's Wager just *ignores* those.
gollark: Pascal's Wager might work if the only options are "no god" or "one god, and it's the one you believe in, and they'll reward you if you believe and punish you otherwise".
gollark: Also, I should be specific, "a god and associated religious claims", not just "a god".
