American Evergreen

Syngonium podophyllum (sin-GO-nee-um po-do-FIL-um)

Family: Araceae Unknown Vine (vertical)

The American evergreen is a tropical perennial shrub or vine in the Araceae family climbing to 6 feet. It is desired in interior settings for its low-maintenance, green or variegated, long-petioled leaves and bush-like habit with some cascading stems. Its blooms are rare in interiors. The ideal location will include a warm setting with high humidity. Avoid locations with full sun, as direct sunlight will tend to burn or bleach the foliage. Typically a perennial, it can be grown as an annual for your containers or other bright but shady locations. Young plants will have a shrubby habit, but as the plant ages, it will take on a vine-like habit. If you wish to retain the arrowhead foliage, cut off the stems as they begin to develop. That will allow the plant to keep a more shrub-like habit. Repotting every few years and trimming the root system can keep the plant manageable. Its flowers are green to greenish white form on a spike and are encompassed by a green-white sheathing bract called a spathe. Groups of flowers form in the leaf axils. As the plant matures, its leaves change shape. Its juvenile form has ovate, heart- or arrowhead-shaped leaves up to 5.5 inches long. They may have a silvery and/or pink variegation. The adult form has longer, narrower leaves. If allowed to climb a tree as it does in nature, the leaves will eventually become pedate (having feet) and contain 5 to 11 leaflets. There are also lobed leaves representing a transition from juvenile to adult stage. This plant is typically sold in its juvenile form. Its uses include use in a hanging basket, as a ground cover, climber, or as a small shrub. Quick ID Juvenile leaf arrowhead-shaped, adult leaf lobed Leaves have long petioles, are sub peltate Bush-like habit with some climbing or trailing stems Insects, Diseases, and Other Plant Problems: Watch for aphids, mealybugs, and spider mites. Bacterial leaf spots and soft rot can occur.
