Flindersia schottiana, commonly known as bumpy ash, cudgerie or silver ash, is a species of rainforest tree in the family Rutaceae and is native to New Guinea and eastern Australia. It has pinnate leaves with mostly ten to sixteen leaflets, panicles of white flowers and woody fruit studded with rough points.
Bumpy ash is disease-resistant and typically not susceptible to illnesses. For care, this plant is fairly low-maintenance. When grown outdoors it needs little watering, and larger specimens usually do not require pruning. Smaller plants should be pruned after they finish blooming. Bumpy ash is suitable for anyone with an outdoor area, such as a garden or deck, and it does not need extensive care experience.
How to keep Flindersia Schottiana.
Light
Bumpy ash naturally occurs in habitats like forest understories and rocky sites, where it grows under natural shade. It prefers partial sun but can tolerate full sun or full shade, showing its adaptable and hardy character.
Temperature
Bumpy ash is fairly adaptable to temperature, able to withstand higher heat and wide temperature swings. In hot conditions, attention should be paid to watering and providing appropriate shade to avoid sunburn. On the other hand, Bumpy ash is not very tolerant of low temperatures; it can endure some cold, but excessively low temperatures may cause frost damage.
Fertilizer
The timing of fertilizing Bumpy ash is important. Fertilize in early spring and continue on a monthly basis until early summer. Fertilizer encourages attractive blooms and supplies energy during both dormant and active growth periods.
Pruning
Bumpy ash is a tree with rough bark and fragrant flowers that thrives when pruned in early spring. To care for this tree, it’s important to remove dead branches, thin out overcrowded areas, and selectively cut to improve its shape and encourage both growth and flowering. These practices help reduce pest risks and enhance the tree's overall health.
