Calling all tattoo artists, knitters, and phlebotomists! Have we got the plant for you. All the charm of its "string of hearts" cousin, but edgier. Like, if Ceropegia woodii is a pink cashmere sweater, the linearis is a black leather jacket.
Give your String of Needles plenty of bright indirect light (although some mild or temporary morning sun is ok), and allow the soil to dry out at least halfway between waterings.
