Saintpaulia ionantha. This strain of African Violets produces a diverse array of flower colours and types, but all have attractively variegated leaves. So even before blooming they make stunning houseplants. Fully mature plants can reach 23-30cm (9-12”) in diameter.
African Violets have been much loved as houseplants since Victorian plant hunters first encountered them growing in Tanzania. They are incredibly diverse, but excellent for indoor growing. They are generally undemanding and thrive best in dappled light.
Moderately easy - African Violet seeds are very, very small. The biggest challenge is dealing with the nearly microscopic seeds.
Zone: Not hardy - for indoor growing only
Start these perennial houseplants at any time of year, as long as the ambient room temperature is steadily in the range of 20-27°C, (68-80°F). Sow the tiny seeds over the surface of dampened seed starting mix. Be sure the mix contains some balanced organic fertilizer, or use fertilized solution when dampening the mix prior to sowing. Otherwise, the seeds will germinate but not grow at all. Germination may start on the 14th day at room temperature, but we have waited for 29 days in some instances. Be patient and keep the soil moist.
Grow indoors only. Provide good window light, but not direct sunlight. Grow lights work well. Seedling growth speeds up after 2 1/2 months, so be ready to pot the plants on as needed. Flowering typically begins after 5-6 months. Use soil that is loose, freely draining, and rich in organic matter. Repot once a year with new soil. Keep the soil slightly moist at all times, and use room-temperature water. Avoid getting the foliage and flowers wet - some people prefer watering them from beneath, into a tray below the pot.
