The moonflower, scientifically known as Strophocactus wittii, is poised to bloom once more at Cambridge University Botanic Garden. Considered “very rare” in captivity, the moonflower garnered global attention in February 2021 when it bloomed for the first time in the UK. This year, the plant has surprised observers by producing four buds, monitored via webcam.
While the moonflower is not uncommon in its natural habitat, it is rare in cultivation. Only 16 botanic gardens worldwide grow this particular species of Strophocactus. Its unique beauty is short-lived, as its flowers start to wither after just 12 hours.
The plant’s unexpected blossoming this year has sparked interest, especially since it tends to reveal itself after dark. In 2022, the moonflower did not bloom, but it flowered again in March last year. The current webcam setup allows enthusiasts to witness the potential blooms, with a special invitation extended to those feeling sleepless or nocturnal.
Cambridge University Botanic Garden staff emphasized that their moonflower, Strophocactus wittii, is distinct from other flowering cacti that share the common name “moonflower.” Senior horticulturist Kathryn Bray highlighted its rarity in the UK and botanic gardens globally, emphasizing the importance of using the Latin name for accurate identification.
