Acnistus cyaneus is a fast-growing container plant known for its stunning bloom.
Native to South America, it can grow into a large shrub or small tree in its natural habitat.
In our climate—provided it overwinters frost-free—it’s a generous bloomer, producing clusters of hanging, bell-shaped flowers in deep purple-blue or violet shades. Sometimes the first blooms appear as early as May, continuing well into October. The flowers attract bees, bumblebees, and in suitable climates, hummingbirds.
In a container, it can reach a height of 2 to 3 meters. Regular pruning helps keep the plant bushy and balanced. We recommend pruning in early spring, before the sap starts to rise. Long stems can also be cut back after flowering.
Acnistus loves sun and warmth. Place her in a sheltered, sunny spot and she’ll reward you with months of flowers. Water generously during summer, but ensure good drainage. During the blooming period, we add liquid fertilizer with each watering to prolong flowering.
From October onwards, as nights grow cooler, the plant may shed its leaves. In winter, keep in a bright, frost-free location at +5 to +10ºC, such as a conservatory, hallway, or garage. Do not feed during winter rest.
In spring, the plant can be repotted and gradually reintroduced outdoors once all frost has passed.
She thrives in full sun and appreciates extra care in the form of warmth and regular feeding.
Hardiness zone 11 (+5ºC).
