Jacaranda [Bignoniaceae] [Jacaranda genus] Alias: Brazilian rosewood, fern tree Latin name: jacaranda mimosifolia Geographic distribution: Brazilian origin, color white, pink, red to purple beautiful. Characteristics: Deciduous trees. Crown tall, 12 to 15 meters high, up to 20 meters. Bipinnate leaves, large leaves, pinna in 16 pairs or more, each pinna with leaflets 10 to 24 pairs, pinnate, with students closely, quite beautiful, leaflets about 6 mm. Panicles, or axillary, carrying sticks, bell-shaped flowers, 25 to 35 cm long, lilac, flowering spring and early summer. Fruit is a capsule, round slightly flat, light brown, about 5 cm in diameter. Yela best flowering. This tree alias, because like fern leaf; aka blue fog tree, dark brown wood. Landscape uses: Furniture can be used as foliage, flowers, trees, can be used for street trees, shade trees and landscape trees. Reproduction: Jacaranda method seeds, cuttings and tissue culture for breeding. Its capsule maturity of 11 months, placed postharvest exposure or no wind at the pile, dried and stored until next March, when the temperature is 20 ℃ sown up and down, but the germination rate of only about 5%. Jacaranda cutting propagation can be carried out in spring and autumn, choose cooked shoots for cuttings, rooting rate. Tissue culture Jacaranda's also easier, some of our research unit has applied seedling stems top and stem segments explants breed a lot of plantlets. Cultivation: (1) temperature and light: Jacaranda is native to tropical America, hi warm and humid, sunny environment, intolerant frost. Optimum growth temperature of 22 至 30 ℃, if the winter temperature is below 15 ℃, growth is stagnant, if there is less than 3 至 5 ℃ cold damage, summer temperatures higher than 32 ℃, the growth is also subject to rejection. Hi light, half shade tolerant. (2) Soil and Fertilizer: hi moist fertile sandy loam or loam, when planting to Shizujifei need after surviving each spring and autumn dressing 1, once a year in early spring pruning pruning, aging plants need to impose heavy shears. When potted plants can be cut dry or grafted dwarf and control of water and nitrogen fertilizer. (3) Pest Control: Jacaranda fewer diseases, pests are beetles, found the trunk base with red-brown fecal debris, can be used to pick a knife to open the bark cortex catch larvae; may also occur in adults before, in the trunk painted lime base 80 cm below 10 copies, a mixture of sulfur and salt prices to prevent oviposition.

Hi light, half shade tolerant. (2) Soil and Fertilizer: hi moist fertile sandy loam or loam, when planting to Shizujifei, after surviving all need fertilizer in spring and autumn fruits Jacaranda 1, once a year in early spring pruning pruning, the plants need to impose aging re-cut. When potted plants can be cut dry or grafted dwarf and control of water and nitrogen fertilizer. (3) Pest Control: Jacaranda fewer diseases, pests are beetles, found the trunk base with red-brown fecal debris, can be used to pick a knife to open the bark cortex catch larvae; may also occur in adults before, in the trunk painted lime base 80 cm below the 10 parts of sulfur and 1 part salt mixture to prevent oviposition.
