Trillium Greenhouse Kit

Trillium Greenhouse – a very popular smaller scale greenhouse that lives large!

The Trillium is made with our unique laminated redwood frame. We use Clear All Heart Redwood — the part that is truly “red” — for superior durability and rot resistance. With the proper care, this small greenhouse will last and look beautiful for years to come.
