Camphor Spurflower (Plectranthus cylindraceus): Rare Aromatic Succulent
The Camphor Spurflower (Plectranthus cylindraceus, formerly listed as "Coleus aromaticus" is a rare, richly aromatic succulent with soft, hairy, thick leaves and a woody, bark-like stem as it matures. Originally distributed through the Huntington Botanical Gardens' International Succulent Introductions (ISI) program, this is a genuine collector's plant rarely seen in general cultivation, perfect for succulent and unusual-plant enthusiasts looking for something with real horticultural pedigree.
Appearance
Small, thick, softly hairy leaves with a fresh, pleasant zesty aroma when brushed. As the plant matures, the lower stem lignifies into a rugged, bark-like base, giving it real character and a semi-shrubby habit.
Lighting & Growth
Thrives in bright light to full sun and prefers to dry out fully between waterings, as this is a true succulent, not a moisture-lover. Well-draining, gritty soil is essential. Not suited to humid, low-light environments; best grown as a houseplant on a sunny windowsill, in a conservatory, or outdoors in warmer months.
How to Use
Ideal as a standalone specimen plant for a sunny spot, in a succulent/mixed dry planter, or as a talking-point addition to a collector's shelf. Its aroma also makes it a pleasant plant to brush past.
