  • Patent number: 5759645
    Abstract: An artificial plant assembly (10) consisting of a stationary central stem (12) and a plurality of rotatable fronds (70). The central stem (12) includes a rigid inner core (14) and a molded outer stem (22). Near the lower terminus (26) of the outer stem (22) is a frond stop (30), a bulbous section (48) located above the stop (30), and extending from the upper end (18) and sides is located a plurality of leaves (58). The rotatable frond (70) also has a rigid inner core (72) and a molded outer stem (80). The outer stem (80) has an upper terminus (82), a lower bulbous section (84), and a plurality of leaves (58) that extend from its upper terminus (82) and sides. The lower bulbous section (84) has an open side (86) and an enclosed lower portion (80) having an opening (90).
