Description
The Grevillea (Grevillea olivacea) "Yellow-Flowering Form" is a radiant medium-sized shrub that sets gardens aglow with its sunny yellow blossoms from Makuru to Djilba (winter to early spring). Smaller and more compact than its traditional red counterpart, this fast-growing Grevillea not only showcases vibrant hues but also beckons native birds, ensuring your garden is both a visual and auditory delight. Native to Western Australia, this cultivar adds a touch of authentic Aussie charm to any space.
For those planting in the ground, enriching sandy soils with a soil conditioner can boost its vigour. As it settles in, the shrub reveals its drought-resistant nature, though it welcomes a dose of low-phosphorus native fertiliser during Djilba (early spring). Keeping its vibrant form intact requires gentle hands, with regular light pruning being ideal while avoiding any heavy trims.
