Grevillea Overview

Description Grevilleas are a diverse group of plants. Look around and you're likely to find everything from ground-hugging evergreen shrubs to stately trees. These plants are related to dramatic proteas and are similarly loved for their intricate and spidery blooms that have a pleasing, sweet fragrance. Grevilleas are subtropical and tropical shrubs and trees that sport a variety of types of foliage. Species with needlelike foliage are especially useful for adding interest to a planting of palms or other tropical plants with big leaves. Broad-leaf grevilleas are a welcome addition to any planting area. Grevillea foliage color ranges from yellow-green to medium and dark green. Bloom colors include white, pink, yellow, and orange.

Planting Grevillea

With such a wide range of plants, there are countless ways you can utilize and enjoy the beauty of grevilleas in your yard. Use the larger-growing tree types to cast shade or act as a windbreak—and do so with beauty and grace. Shrubby types can be used as hedges and privacy screens or planted to provide an extra dose of color and texture in the back of garden beds and borders.

Compact types grow well in large containers, so you can enjoy these varieties on your deck or patio, even if you don't have a yard to plant them in. And because most types like hot weather, they're good choices for containers on driveways and other paved spots.

If you don't live in the subtropics, you don't have to feel left out. If you have a high-light spot inside, you can even grow these beauties as dramatic houseplants.

Grevillea Care

Most grevilleas come from Australia and islands in Southeast Asia. As such, they tend to appreciate warm temperatures and long growing seasons. Most varieties will not survive frosty or freezing temperatures. If you live in an area that only occasionally sees frosts, plant grevillea in a protected spot, such as near a building for protection, or grow them in containers so you can move them into a garage or shed overnight when it gets too cold for them outside.

These trees and shrubs grow best in a spot that sees full sun (at least 8 hours of direct sun per day) with well-drained soil. Once established, they tend to be drought tolerant—so you can practically plant them and forget them. That said, be careful not to overwater—most are sensitive to root rot. The plants don't usually thrive in a spot that sees regular irrigation or regularly sees standing water.

Indoors, grow grevillea in a spot with bright light. Select a container with drainage holes and pot them in a mix formulated for cacti and succulents. Take care never to overwater them.
