The sandbox tree's fruits are large, pumpkin-shaped capsules, 3–5 cm (1–2 in) long, 5–8 cm (2–3 in) diameter, with 16 carpels arranged radially. Its seeds are flattened and about 2 cm (3 ⁄ 4 in) diameter. The capsules explode when ripe, splitting into segments and launching seeds at 70 m/s (250 km/h; 160 mph). [5]
Tabebuia rosea, also called pink poui, and rosy trumpet tree [2] is a neotropical tree that grows up to 30 m (98 ft) and can reach a diameter at breast height of up to 100 cm (3 ft). The Spanish name roble de sabana , meaning "savannah oak", is widely used in Costa Rica , probably because it often remains in heavily deforested areas and because ...
In some cases the seed is in the centre of the wing, as in the elms (genus Ulmus), the hoptree (Ptelea trifoliata), and the bushwillows (genus Combretum). In other cases the seed is on one side, with the wing extending to the other side, making the seed autorotate as it falls, as in the maples (genus Acer) and ash trees (genus Fraxinus). [4]
According to Frazer, birds' droppings often contain rowan seeds, and if such droppings land in a fork or hole where old leaves have accumulated on a larger tree, such as an oak or a maple, they may result in a rowan growing as an epiphyte on the larger tree. Such a rowan is called a "flying rowan" and was thought of as especially potent against ...
Propagation of this tree is easy. The seeds are just flying around. These seeds can be planted in moist soil in a nursery bag or directly at the permanent location using direct seed plantation method. Sticks of bamboo can be used for marking and support. Germination takes place after about 10 days. The tree is quite fast growing. These trees ...

The tree is briefly deciduous, and it is during this leafless period that it blooms with umbels of large flowers ranging from creme de menthe to red in color. [17] After blooming, the trees produce several hundred 15 cm (6 in) pods containing seeds surrounded by a fluffy, yellowish fibre that is a mix of lignin and cellulose.
As the seed ripens the wings dry and the long edge furthest from the seed curls slightly upwards. When ripe, a hole forms in the bottom of the gourd, the seeds drop off, and their aerodynamic form allows them to glide away from the tree. [6] [7] The wing spans around 13 centimetres (5 in) [8] and can glide for long distances.
