Most artificial foliage is not built to live outside. Polyblend is the material ours is made from, and this page explains what it is and why it holds up when ordinary foliage fails.
The plastics, ranked
Of the plastics used in artificial foliage, ordinary imported polyethylene is the weakest — in lab exposure testing it breaks down after 200 to 500 hours. Cast vinyl does better, bottle-brush vinyl better still. Polyblend is a high-grade industrial polyethylene blend with UV stabilizers compounded into the resin itself, not sprayed on. The same lab test ran 4,162 hours on Polyblend without noticeable change.
All pigmented plastic shifts color slightly as it ages. With light-fast pigments the change is slow and stays well below what the eye objects to — which is why the pigment quality matters as much as the resin.
How long it actually lasts
Location decides it. Under the severe UV of the Deep South and Southwest, outdoor Polyblend foliage stays intact three to five years. In northern climates seven years is normal, and plenty of northern installations still look right after ten.
Built as one piece
Outdoor foliage also has to survive wind, snow load and handling. Indoor-grade shrubbery is assembled from small segments stacked on weak center rods; it is not designed for weather and fails in it. Polyblend plants are molded with stalks, branches and twigs as one integral unit, with reinforcing wire through every branch running into a bundle at the stem — strong, flexible, and able to hold shape through a storm.
Fire rating
The Polyblend formula is also available inherently fire retardant, passing NFPA 701 and UL-94 — the reason our foliage can be specified for indoor venues, tents and event spaces where fire marshals ask questions. This is the material behind the fire-rated claim on our event topiary work.
Where it makes sense
Polyblend was designed as a problem-solver for hard-to-grow and hard-to-reach places: full-sun frontages, rooftops, planters nobody can water, and installations where live maintenance is impractical. Browse the outdoor topiary collection, compare it honestly against live planting in faux vs real, or ask about custom work in the material.
Does where it lives change how long it lasts?
More than anything else. Southern states get more sunlight and stronger UV, and year-round exposure accelerates deterioration in a way northern installations never see. Salt air near the ocean and sustained high humidity work on a piece too, so a coastal installation ages faster than an inland one in the same state.
That cuts the other way in the north. Where winters are hard, bringing Polyblend pieces in for the worst months measurably extends their life compared with leaving them out year-round. If a piece is portable and the winter is severe, storing it is the single cheapest thing you can do for it.
Fire testing is worth one more line, because specifiers ask: the inherently fire-retardant formula meets NFPA 701 for non-flammability and ASTM E84-95, the standard test method for surface burning characteristics of building materials.
Cleaning and fade care for an installed piece are covered in do artificial topiaries fade.
