Red Pillar Hibiscus

Growing it in South Louisiana.

Red Pillar® rose of Sharon is Hibiscus syriacus ‘GFNHSRP’, a deciduous shrub with a naturally columnar shape. Expect approximately 10–16 ft tall and 4–5 ft wide in USDA zones 5–9. Dark pink flowers with large red centers appear in summer. Give it at least six hours of sun and soil that drains well. Low once established; water deeply during prolonged dry spells. Water regularly while establishing and monitor container plants more frequently. For Southeast Louisiana, avoid low spots that stay saturated after heavy rain; mulch without covering the crown. Pruning is usually minimal; if needed, prune in early spring before flowering on new growth. Allow time for spring leaf-out. Its flowers attract bees, butterflies, and hummingbirds, and its slim outline offers seasonal screening without the footprint of a spreading shrub.
