Description:

Cryptanthus bivittatus, commonly known as the Earth star, is a diminutive terrestrial plant belonging to the Bromeliaceae family. The moniker “Earth star” is derived from the triangular configuration of its leaves, arranged in a spiral rosette where the outer leaves exhibit greater length while the central ones are more compact, creating a star-like appearance when viewed from above. The term “Earth” is associated with its modest stature, reaching a height of 6 to 8 inches. In its natural habitat, this plant thrives under conditions of moderate or diffused light, accentuating its distinct red hue. Crypthantus bivittatus ‘Rubin star’ share these main characteristics with the wild species Cryptanthus bivittatus: the main difference lies in the more intense red colors of the leaves, that is the reason for the epithet ‘Rubin star’ and it’s distinguished in a purple-bownish, almost black stripe, and scarlet red margins. Similarly to the structure of Cryptanthus bivittatus, the variety ‘Rubin star’ has outer leaves slim between the part that wraps around the stem and the flat portion but that don’t have a real stalk. The wrapping parts are short, wide, and have tiny saw-like edges, while the flat portions are long and pointed, measuring about 4 cm in width. The edges of the leaves have small saw-like notches and a wavy shape. Similar to every plant within the Bromeliaceae family, Cryptanthus bivittatus ‘Rubin star’ flowers only once in its lifetime before reaching the end of its life cycle. The petite white blooms it produces add a burst of color to indoor spaces.

Position your Cryptanthus bivittatus ‘Rubin Star’ in direct sunlight, ensuring protection from the scorching midday sun during the peak summer hours to accentuate the vibrant hues of its leaves. Maintain a warm environment, safeguarding it from the chilliest winter months, with temperatures ideally staying above 10ºC and ranging around 20-24ºC for optimal growth.
Originally hailing from humid climates, Cryptanthus bivittatus ‘Rubin Star’ thrives on regular misting, especially in the summer when increased air humidity fosters superior development.

Propagation:

Propagating Cryptanthus bivittatus ‘Rubin Star’ is a simple process that primarily involves utilizing small shoots emerging from the base of the plant, commonly referred to as offsets.
