Calathea Surprise Star is a stunning member of the Marantaceae family, native to the tropical rainforests of South America. Calatheas are admired for their ornate foliage, and this cultivar is particularly eye-catching, with its vibrant colours and striking patterns.
The leaves are broad and oval, with a rich dark green base decorated with pale green to silvery stripes radiating from the midrib, almost brushstroke-like in effect. Each leaf underside is a deep burgundy-purple, creating a bold contrast when the plant folds its leaves upwards at night a behaviour known as nyctinasty, common to prayer plants. The name Surprise Star comes from its unexpected burst of colour and the star-like effect of its leaf markings.
Compact and bushy, Calathea Surprise Star typically reaches 4060 cm in height indoors, making it an ideal tabletop or floor specimen that adds an instant tropical feel to interiors.
Thrives in bright, indirect light. Tolerates lower light, but vibrant patterns may fade. Avoid direct sunlight, which will scorch delicate foliage.
Keep soil evenly moist but not waterlogged. Water when the top 23 cm of soil feels dry. Calatheas are sensitive to hard tap water use filtered, rain, or distilled water if possible to avoid leaf spotting.
Temperature: Prefers 1826C. Protect from cold draughts and avoid drops below 15C.
Humidity: Requires high humidity (6080%). Mist regularly, use pebble trays, or place near a humidifier. Dry air can cause crisp leaf edges.
Use a light, airy, and free-draining peat-free compost with added perlite or coco coir. Repot every 12 years in spring to refresh the mix.
Apply a balanced liquid fertiliser every 46 weeks in spring and summer. Avoid overfeeding, as Calathea roots can be sensitive.
Remove any yellowing or damaged leaves at the base to encourage fresh growth. Wipe the broad leaves with a damp cloth to maintain their colour and sheen.
A moderate grower, forming a dense clump up to 4060 cm tall and wide indoors. Provides year-round interest with its bold foliage.
Brown edges: Often due to low humidity or fluoride in water.
Curling leaves: Underwatering or low humidity.
Faded patterns: Too little light.
Pests: May occasionally attract spider mites, aphids, or thrips.
Calatheas are often called living art thanks to their colourful patterns. Surprise Star is one of the more dramatic cultivars, combining star-like variegation with rich purple undersides. As a non-toxic plant, it is also safe for homes with pets or children.
