Philodendron x 'Xanadu' 'Xanadu' Philodendron1

Edward F. Gilman2

Introduction

This moderately large-leaved, easily grown philodendron makes a dramatic, tropical statement wherever it is used in the landscape (Fig. 1). The deeply divided, usually drooping, dark grey-green leaves grow up to 18 inches long and 8 to 12 inches wide, appearing on long, smooth petioles. Each leaf is divided into 15 to 20 lobes. It can be grown outside only in south Florida and in the warmest parts of central Florida. The flower is not showy.

Use and Management

When given enough room to spread, 'Xanadu' makes a handsome foundation or specimen planting, and can also be used in large containers, where it looks especially attractive at poolside. It has similarities in texture and form to selloum without its large size. Space 4 or 6 feet apart in a landscape to form a mass planting of coarse textured foliage. Since leaves remain close to the ground, it makes a nice, tall ground cover for any shaded, damp location.

'Xanadu' is well adapted to the shade of tall trees. It needs fairly rich, moisture-retentive soil to look its best. Most philodendrons adapt to alkaline soil fairly well and are resistant to drought.

Pests and Diseases

Infrequent pests include mites and scale.
