Philodendron 'Imperial Green' – Care and Growing Guide

Philodendron 'Imperial Green' is a striking hybrid with large, glossy dark green leaves and a self-heading, rosette growth habit. Unlike climbing philodendrons, 'Imperial Green' remains upright and compact, making it an ideal choice for modern interiors. The rigid petioles with a pink-tinged sheath add an extra decorative element, while its short internodes (~1 cm apart) ensure a dense, full appearance.
