Impatiens austrotanzanica x I. polyantha Hell. is a hybrid plant derived from the cross-pollination of two different impatiens species. This plant is commonly referred to as Busy Lizzie or Patience Plant and is widely grown for its colorful flowers.
Seed Propagation
The easiest and most common way to propagate Impatiens austrotanzanica x I. polyantha Hell. is by seed. Collect ripe seed pods from the plant and allow them to dry completely. Once the seed pods have dried, break them open and collect the seeds. Sow the seeds in a well-draining seedling tray filled with a potting mix. Cover the seeds lightly with soil and mist the surface with water. Keep the seed tray in a shaded area and maintain a constant moisture level. Within 2-3 weeks, the seeds will germinate and form young seedlings. Once the seedlings have grown to a sufficient size, they can be transplanted to their permanent location.
Stem Cuttings Propagation
Impatiens austrotanzanica x I. polyantha Hell. can also be propagated through stem cuttings. Take a 4-6 inch long cutting from a healthy parent plant, making sure to include a few sets of leaves. Remove the lower leaves and dip the end of the cutting in rooting hormone. Stick the cutting into a well-draining potting mix and place it in a warm and shaded area. Keep the soil moist and within 3-4 weeks, the cutting will develop roots. Once the cutting has established roots, it can be transplanted to a permanent location.
Division Propagation
Division propagation method is rarely used in Impatiens austrotanzanica x I. polyantha Hell. However, mature plants can be propagated through division. Remove the plant from its container and separate the root ball into smaller sections. Each section should have some stem and leaves. Replant the divided sections in well-draining soil and water well. Place the new plants in a shaded area and maintain a consistent moisture level. Within a few weeks, new growth should appear.
