The foliage is a basal rosette, and stems can grow up to 20 cm tall with one flower per stalk. Houstonia caerulea thrives in moist acidic soils in shady areas, growing especially well among grasses.
Although Azure Bluet is a super rare houseplant, it is easy to grow and needs regular watering to thrive. It does best in long-lasting, direct light and should be less than 1 foot from a window.
