Description

Pseuderanthemum atropurpureum, often called Purple Eranthemum or Purple Leaf Bush, is a vibrant shrub that features striking purple foliage and attractive flowers. The plant’s deep purple leaves create a dramatic contrast with its delicate, funnel-shaped white to light purple flowers that appear in clusters. Ideal for brightening up tropical and subtropical gardens, this shrub is a showstopper when used as a hedge or accent plant. The rich colors and easy-growing nature of Pseuderanthemum atropurpureum make it a popular choice for gardeners seeking both beauty and low-maintenance appeal.

Light requirements

Pseuderanthemum atropurpureum thrives in full sun to partial shade. For the best color and dense growth, it should be planted in a sunny spot that receives at least 4 to 6 hours of direct sunlight each day. In partial shade, the plant will still grow well but may not show as vibrant foliage or as many flowers. A balance of sunlight is key to achieving its best appearance.

Soil preferences, including pH and drainage

This shrub prefers well-draining, slightly acidic to neutral soil with a pH range of 6.0 to 7.0. It does well in sandy or loamy soils that drain well but can tolerate poorer soils as long as they do not retain too much moisture. Proper drainage is crucial to avoid root rot, so it's best to plant in an area that doesn’t stay too wet. If growing in containers, ensure that the potting mix provides adequate drainage.

Water needs

Pseuderanthemum atropurpureum has moderate water requirements. Water regularly, allowing the soil to dry out slightly between waterings. It prefers consistent moisture but is somewhat drought-tolerant once established. Overwatering can lead to root rot, so be sure not to let the plant sit in standing water. During the cooler months or when the plant is less active, water less frequently but ensure the soil doesn’t dry out completely.
