The jacaranda is a small, beautiful flowering tree that grows well in warm climates. Jacaranda is most commonly grown as an ornamental in yards and parks. However, it's also well suited for bonsai growth. Jacaranda is easy to propagate by cuttings and seed. Cuttings will produce flowers in a season or two. Jacarandas grown from seed will take years to reach flowering age. The best way to start a jacaranda from seed is to plant it indoors in spring. After a year of indoor growth, it will be ready for transplantation outdoors the following spring.
Fill an 8-inch pot to within 1/2 inch of its lip with moistened commercial potting soil.
Place a jacaranda seed in the center of the pot and press it down with your finger to ensure good soil contact.
Cover the seed with 1/8 to 1/4 inch of horticultural sand.
Moisten the sand layer with water from a spray bottle.
Place the pot in a warm, window-adjacent spot where it receives full sunlight (six to eight hours per day).
Check the soil's moisture level once daily. Stick your finger into the soil (away from the center). If the soil feels dry, water it with your spray bottle until the soil is moist again.
Water the jacaranda seedling less frequently once the seed germinates (in two to three weeks). Test the soil's moisture level with your finger, and water with a watering can only when the top third of the container's soil dries out.
