Description
Tabebuia rosea is a medium to large-sized deciduous
tree up to 25 m high. Flowers purplish-pink to nearly white, up to 8 cm long.
Fruit a linear dehiscent capsule containing many winged seeds. The generic name
is after the Brazilian local name for Tabebuia serratifolia.
Propagation methods
Seed is produced in moderate quantity, and natural
regeneration is found in the vicinity of seed bearers; cuttings root quickly.
Established mostly by direct sowing and subsequent planting out to permanent
sites when about 60 cm high. It can also be propagated by branch
Tree Management
T. rosea is fast growing, especially when young. Trees
withstand a limited amount of pruning but not pollarding. In Sri Lanka, early
growth is faster than that of any other ornamental tree used in the country,
reaching a height of over 9 m in about 3 years at Colombo. Where conditions are
not favourable, bark-burst has been observed. The lifespan is about 50 years.
Germplasm Management
Seed storage behaviour is intermediate; seeds tolerate
desiccation to 7.1% mc (99% germination), storage temperature of 5 deg. C;
viability is maintained for 30 months in hermetic air-dry storage at 10 deg. C.
There are about 42 000 seeds/kg.
