Nature cannot produce a tree that is rot resistant, disease free, insect free, and fire retardant; however, at Oasis Illusions, we can! Our leaves are grown with quality control by a trained horticulturist right here in the United States. Each preserved washingtonian palm tree leaf is transformed indefinitely. The water inside the harvested washingtonia leaves is replaced with a safe organic formula. Each preserved palm tree is internally transformed, which allows the fronds to maintain their lush feel, flexibility, natural color and texture, indefinitely. Furthermore, this process also makes the preserved washingtonian palm tree leaves internally fire retardant (IFR.) Our fire retardant formula will meet even the strictest fire codes.
