Grow your container garden in lovely, durable and lightweight Supreme Fiberglass Flowerboxes. Did we mention they're maintenance-free too? Using an "extruded" manufacturing technique the material is formed into a classic shape, finished here in a smooth, matte white. Keep containers as is or use your own paint for simple color matching. Wall planters even come with a pair of standard stainless steel brackets and bolts for a ready-to-mount product on arrival.

Fiberglass flower boxes are an all-weather garden container that can handle extreme hot or cold. As for watering, orders include a matching drainage mat that is custom fit to the 36" planter size. This covering routes excess water over the convex container bottom to runoff through holes in the end-cap. The mat is all that's required to keep both drainage and air circulation optimized to nourish healthy plants and prevent damaging root rot.

Order Supreme Fiberglass Flowerboxes online in standard sizes or call toll free for custom lengths. This product can be manufactured in unique dimensions and as over-sized planters measuring up to 14' long.
