How it Works: Preen Garden Weed Preventers
Here's how our Garden Weed Preventers prevent weeds before they even sprout rather than killing them after they’ve already had the chance to grow.
These giants of the plant world add bold statements to any yard.
Most plants take in all the sunlight they need with leaves somewhere between the size of a fingernail and dollar bill. Then there are the giants of the plant world that over-achieve to produce leaves that rival big-screen TVs. These add bold statements to any yard and contrast nicely with their “normal-sized” neighbors.
These are tropicals that can grow three to four feet tall with heart-shaped leaves that can span two feet or more. Leaf colors include lime to nearly jet black in addition to various shades of green. Elephant ears grow in sun or shade, in pots or the ground, and their tubers can be dug and saved inside over winter in cold climates.
Caladium is another tropical tuber (similar to elephant ears) that produces colorful, heart-shaped leaves all summer, preferably in shade to part sun. These aren’t quite as big as elephant ears but come in assorted beautiful variegated shades, including white, green, pink, rose, and burgundy. The tubers also can be dug and saved over winter in cold climates.
Here’s the king of the big leaves – a tender perennial (winter-hardy in Zone 7 and warmer) that can grow eight feet tall with four-foot leaves. The leaves are green with toothed edges, and the fat stems are prickly. Gunnera does best out of hot afternoon sun and in moist soil.
