Gloxinum Avanti F1 (Sinningia speciosa Avanti F1). Unbeatable, one of the earliest flowering series of gloxinia, with a wide range of bright, original colors. The bush is compact, 20-25 cm high. Leaves are small in size. There are 10-15 large flowers formed on an adult plant. Heat-loving culture, optimal growing temperature + 20-25 ⁰С, in winter + 10-14 ⁰С. Illumination is bright, diffuse. In the period of active growth and flowering needs abundant watering, fertilization, wet air. Seeds are sown superficially in February and March. Cover the planting tank with film or glass and put in a warm, bright place. Ventilate and keep the substrate moist. Optimal temperature + 20-22 ⁰С. After sprouting, the glass is removed. In phase 2-3 of real leaves the plants are planted in separate pots. Looks great in cachepot and containers in summer.
How to Grow Gloxinia from Seeds Gloxinias on display in the garden center are lovely and well worth the price, but frugal growers may want to try their hand at growing them from seeds. The roots are tender and the plant is not easy to transplant to a larger container when it is young, so start the seeds in a 4- to 6- inch (10 to 15 cm.) pot where it can grow to full size. Fill the pot to about 1 1/2 (3.5 cm.) inches from the top with African violet potting soil. Sift an additional 1/2 (1 cm.) inch of soil through a screen into the top of the pot so that the tender roots won’t have any difficulty pushing through the soil when the seeds germinate. Moisten the soil and press the seeds gently onto the surface. Seeds need light to germinate, so don’t bury them. Place the pot in a plastic bag and seal the top to keep the soil moist and the air humid. The seeds will germinate in three or four days. At that time, open the top of the bag, and remove it completely after a week. Mist the soil when the surface feels dry.
