How to Grow Callisia navicularis

Overview

Callisia navicularis, also known as Blue Star Flower or Water Hedwigia, is a beautiful and unique addition to any garden. Native to Mexico, this flowering plant belongs to the Commelinaceae family and has earned the Royal Horticultural Society's Award of Garden Merit for its stunning appearance and hardiness in warm temperate climates.

Growing Conditions

Callisia navicularis thrives in well-draining soil and bright, indirect light. These plants are sensitive to cold temperatures and should be grown indoors or in a greenhouse in cooler regions. They prefer a temperature range between 60°F and 75°F (15°C - 24°C) and can tolerate slightly higher humidity levels.

Planting & Care

Plant Callisia navicularis in a pot with drainage holes filled with well-draining, fertile soil. Water the plant regularly to keep the soil moist but not soggy. Fertilize monthly during the growing season to encourage healthy growth. Pruning is minimal, as these plants have a mounded growth habit and do not require frequent pruning.

Common Problems

Overwatering or poor drainage can lead to root rot in Callisia navicularis. If you notice yellowing leaves or wilting despite consistent watering, check the soil moisture level and adjust your watering schedule accordingly. Pests are usually not an issue for this plant, but watch out for common houseplant pests like spider mites or aphids.

Harvest or Enjoy

The most enjoyable aspect of growing Callisia navicularis is its vibrant blue flowers that bloom from spring to summer. The delicate star-shaped blooms can be enjoyed in a bouquet or left on the plant to attract pollinators. As these plants spread and fill their pots, they create a visually stunning display that will brighten any room or greenhouse.
