Philodendron selloum Selloum1

Edward F. Gilman2

Introduction

This large-leaved, easily grown philodendron makes a dramatic, tropical statement wherever it is used in the landscape, eventually developing a three- to four-foot-long, tree-like trunk and a spread of 8 to 10 feet (Fig. 1). The deeply divided, usually drooping, medium green leaves grow up to three feet long and 12 to 18 inches wide, appearing on long, smooth petioles. It can be grown outside in central and south Florida, and in a protected area in Gainesville or Jacksonville.

Use and Management

When given enough room to spread, selloum makes a handsome foundation or specimen planting, and can also be used in large containers where it looks especially attractive at poolside.

Although appearing as if it would need deep shade, selloum actually grows quite well in full sun or partial shade, and needs fairly rich, moisture-retentive soil to look its best. Most people planting this shrub forget how large it can grow.

The cultivar 'Lundii' is more compact in form.

Propagation is by division of the offshoots or from seed.

Infrequent pests include mites and scale.
