Pisonia grandis, commonly called bird-catcher tree, birdlime tree, lettuce tree or cabbage tree, is a soft-wooded, brittle-branched tree of the Bougainvillea family that grows to as much as 60-80’ tall. It is often found growing in dense stands on coral cays. Thickets of this tree are favored nesting sites for certain seabirds.
Long-petioled, elliptic, light green leaves to 12” long. The leaves are used in the treatment of dysentery.
Pisonia bears funnel-shaped, clusters of green sweet-smelling flowers that mature into sticky barbed seeds and bloom summer to fall. Female flowers give way to elongate cylindrical fruits with sticky prickles.
Pisonia requires a soil rich in potassium and a position in full sun or light shade. Water the plant frequently during the dry season. The soil should be constantly slightly moist, but not wet. In winter, water no more often than every 8-12 days. From spring to autumn liquid balanced fertilizer every 3-4 weeks. It responds well to fertilizing with organic fertilizer.
It can be planted as an avenue plant
Plants with thin leaves need daily watering and ones with thick leaves need watering 3-4 times a week. This will also depend on the season. Generally during the blooming period, plants love a lot of water. Try keeping the soil moist. During winters it is better to cut back on watering.
Keep the plants in a well drained soil with a drainage hole at the bottom. This will help to avoid over watering. Take care as to not leave stagnant water on top of the soil. Fertilise the plant once in 2-3 weeks during its blooming period. Do not fertilise it in winters.
