About Java Glorybower
A showy tropical shrub that produces towering panicles of brilliant orange-red to scarlet flowers that can reach 30 cm tall, creating a fiery vertical display above large, heart-shaped velvety leaves. It blooms heavily during the Philippine rainy season when many other plants struggle. The flowers are a magnet for butterflies and hummingbirds. Java Glorybower belongs to the Lamiaceae family and originates from Java, Indonesia, and other parts of tropical Southeast Asia. Naturalized in many Philippine provinces..
The Java Glorybower and its relatives are common in Philippine gardens, especially in provinces with abundant rainfall. The related Clerodendrum quadriloculare is actually native to the Philippines and blooms with stunning pink-white starburst flowers in January-February. These plants are popular in barangay and church gardens. Available at budget-friendly prices in provincial nurseries. The Bleeding Heart Vine (Clerodendrum thomsoniae) is another popular relative frequently seen trailing over Filipino garden fences.
Also known as: Java Glory Vine, Pagoda Flower.

Aggressive suckering and spreading

Solution: Plant in contained beds or use root barriers. Remove suckers regularly. Grow in large pots to control spread entirely.
Leggy, sparse growth
Cause: Insufficient light or lack of pruning
Solution: Prune back by half after flowering to encourage bushy regrowth. Provide more light.
Whiteflies and mealybugs
Cause: Lush, soft foliage attracts sucking insects
