Before selecting companions, one must first understand the oleander's (Nerium oleander) own needs and characteristics. We are a large, dense, evergreen shrub that thrives in full sun and well-drained soil, tolerating drought, salt spray, and poor soils with ease. Our most critical trait to consider is our toxicity; all parts of our being are poisonous if ingested. Therefore, any plant placed near us must not be an attractive food source for children or pets. Our extensive root system is also quite efficient at drawing water and nutrients, meaning our companions must be able to compete or, more wisely, share our tolerance for drier conditions once established.
To create a visually cohesive landscape, consider plants that complement our form and texture. Our foliage is long, leathery, and dark green, providing a perfect backdrop for plants with contrasting leaf shapes or colors. For a striking architectural statement, pair us with the bold, sword-like leaves of Yucca or the dramatic, symmetrical form of a Sago Palm (Cycas revoluta). The fine, feathery texture of Mexican Feather Grass (Nassella tenuissima) or the silvery, soft foliage of Artemisia creates a beautiful softness at our base, contrasting sharply with our own dense, rigid structure.
While we offer prolific blooms in shades of white, pink, red, and yellow throughout the warm seasons, strategic companions can extend the color display. For brilliant, drought-tolerant blooms that mirror our love for the sun, consider the sprawling vibrancy of Lantana or the bold, daisy-like flowers of African Bush Daisy (Gamolepis chrysanthemoides). The intense purple spikes of Mexican Sage (Salvia leucantha) or the electric blue flowers of Plumbago auriculata provide a stunning color contrast to our typically warm-hued flowers. For a more subdued palette, mass plantings of Society Garlic (Tulbaghia violacea) offer delicate lavender blooms and strappy foliage.
The ground beneath our canopy can often be dry and shaded. Selecting the right underplanting is crucial for both aesthetics and soil health. Drought-tolerant, shallow-rooted ground covers are ideal. Dwarf Rosemary offers aromatic foliage and blue flowers, thriving in the same conditions we do. For a carpet of color, Ice Plant (Delosperma cooperi) is a superb choice, blanketing the soil in vibrant magenta flowers. The tough, sprawling Trailing Indigo Bush (Dalea greggii) provides soft gray-green foliage and purple flowers, helping to suppress weeds and prevent soil erosion around our base.
