Jacaranda Mimosifolia, Blue Jacaranda, Fern Tree, Black Poui 50-100 seeds
Jacaranda mimosifolia is a sub-tropical tree native to south-central South America that has been widely planted elsewhere because of its attractive and long-lasting violet-colored flowers. It is also known as the blue jacaranda, black poui, or fern tree. Older sources call it J. acutifolia.
The blue jacaranda has been cultivated in almost every part of the world where there is no risk of frost; established trees, however, tolerate brief spells of temperatures down to around −7 °C (19 °F). In the US, in areas where winter temperatures can dip to −12 °C (10 °F) for several-hour periods, the mature tree survives with little or no visible damage. Even when young trees are damaged by a hard frost and suffer dieback, they will often rebound from the roots and grow in a shrub-like, multi-stemmed form. However, flowering and growth will be stunted if the jacaranda is grown directly on the California coast, where a lack of heat combined with cool ocean winds discourages flowering.
The tree grows to a height of up to 20 m (66 ft). Its bark is thin and grey-brown, smooth when the tree is young but eventually becoming finely scaly. The flowers are up to 5 cm (2.0 in) long, and are grouped in 30 cm (12 in) panicles. They appear in spring and early summer, and last for up to two months. They are followed by woody seed pods, about 5 cm (2.0 in) in diameter, which contain numerous flat, winged seeds. The blue jacaranda is cultivated for the sake of its large compound leaves, even in areas where it rarely blooms. These leaves are up to 45 cm (18 in) long and bi-pinnately compound, with leaflets little more than 1 cm (0.39 in) long. There is a white form available from nurseries. ©Wikipedia
Sowing time: spring – summer
Germination temperature: 20-30°C
Pre-Treatment: soak in lukewarm water for 12-24 hours
Sowing mix: compost + perlite or sand, ready made compost for seeds and cuttings
Water: moist potting mix, not wet
Germination time: 10 days and more
Germination Method: soak the seeds in lukewarm water overnight or 24 hours. Prepare the pot with potting medium with 1 part of compost and 1 part of sand or perlite (ready made compost for seeds will works as well). Sow the seeds 2 cm apart and cover lightly with medium. Spray with water and keep moist during the germination time. I covered my seedling tray with the lid to retain moisture and maitain higher tempeture. The sprouts should appear in about 10 days and keep popping up another 2-3 weeks. When the seedlings have 4 and more true leaves you can transplant them into individual pots.
