How to Grow Gloxinias
Often gifted at housewarmings, Gloxinias make spectacular houseplants during winter months. However, they will easily make the move from indoors to outdoors in the summer, especially if you start growing the tubers in late February to early March. Gloxinias boast large, velvety leaves and their abundant cup-shaped blossoms in rich hues make for a perfect table centerpiece at summer BBQs.
Start with a container at least 4-6” in diameter with a drain hole and saucer. Gloxinias grow to 20 cm (8”) in height and width. Try grouping 2-3 tubers in larger containers for more impact. Plant the tubers hollow side up, ½ inch deep, in a moistened well-draining potting soil mix.
How much should I water my tubers?
Water sparingly to keep the soil moist until the first leaves begin to grow. Gloxinias are sensitive to cold water, so lukewarm water is best. Water only when the soil feels dry and avoid watering gloxinia leaves directly. Try placing the pot in a shallow saucer of water and let it sit for about an hour.
