Select an area of the yard to plant oleander and bottlebrush. The two shrubs do best in full sun. Bottlebrush prefers fertile, moist but well-drained soil, while oleanders are tolerant of most soils.
Cover fences or walls with oleander to offer privacy to a backyard or cover up unsightly walls. Space the oleander about 6 to 12 feet apart to provide enough space to grow and spread out. Trim oleander into a hedge-like shape or remove lower branches to create miniature trees, 6- to 12-feet-tall. Some varieties of oleander can grow up to 20 feet, so choose a variety according to your needs.
Plant oleander around the yard as a border shrub or place it between property lines if there are no fences or walls. Incorporate oleander into the landscape to act as a screening shrub or wall of foliage for any landscape design.
Place bottlebrush into the corners of the landscape to create depth in the yard. Use bottlebrush as a shrub, like oleander, or trim it into the shape of a tree as it grows to add vertical interest to the landscape. Bottlebrush trees grow to a height of 15 feet. When using it as a hedge, space plantings 10 to 15 feet apart to accommodate spread.
Surround a porch or patio with bottlebrush in the shape of a hedge to create privacy to outdoor seating areas or trim it into a tree to provide shade.
