Philodendron erubescens, known as blushing philodendron, imperial red, pink princess, red emerald and imperial green,[1][2] is a species of flowering plant in the family Araceae, native to Colombia. The specific epithet erubescens means "blushing".[3]
Description
It is a robust evergreen climber growing to 3–6 m (10–20 ft), with red stems and heart-shaped leaves up to 40 cm (16 in) in length. The flowers are deep red, fragrant spathes up to 15 cm (6 in) long, in summer and autumn.[4] The trunk is green with reddish internodes, greyish in old plants. The shoots are tender, brittle.
The leaves are ovate-triangular, 18-25 cm long, 13-18 cm wide, leathery, dark green, with pinkish edges; young dark red-brown. Scape 20–25 cm long, purple at base.[5]
Cultivation
With a minimum temperature of 15 °C (59 °F), in temperate regions it must be grown under glass or as a houseplant. It has gained the Royal Horticultural Society's Award of Garden Merit.[2] The plant can be propagated by offshoots or air layering.
They thrive in bright or in partial shade, but they should avoid direct sunlight; watering should be in moderate amount, not allowing drying or waterlogging of the soil; very large plants should be fertilised from spring to autumn once a week, the rest - once in two weeks, in winter - once a month; leaves often need to be sprayed or wiped with a damp cloth; the temperature should be moderate, in winter not lower than 12°C. As a relaxed stem, it must be secured against a peat cane or other support provided.[6]
Cultivars
Hybrids of P. erubescens with other Philodendron species are common in cultivation, for instance P. 'Pink Princess'.[7] Other cultivars include 'White Princess', 'Gold', 'Black Cardinal', 'Rush', 'Red Emerald Marbled', to name a few.
A popular cultivar in Australia is the Imperial Red and Imperial Green, which have an immobile, scarcely visible stem, that keeps the plant erect and elegant looking as it develops. They feature satiny, gleaming green to red, oval shaped leaves that are clustered very close together on a single stem.[8]
Pests and diseases
The plant attracts mealybugs and aphids. Erwinia is a type of harmful plant bacteria that can affect the plant.
