Distinguishing attributes. The leaves of all grevilleas have beautiful texture, but I am especially fond of this needlelike leaves of ‘Noellii’ — similar to that of rosemary or Westringia.
‘Noellii’ is dense and voluminous, simultaneously airy and light. Its moderate green kind floats softly over the landscape. ‘Noellii’ isn’t a showy plant, but it complements surrounding plants, making sure that garden features look their best. It’ll grow and gracefully spread around 4 feet in each direction but can be pruned after blooming to maintain a dense form.
Clusters of small, white and pink spidery flowers bloom late winter and into spring. They’re magnets for hummingbirds — their elongated type is a open invitation.
How to use it. Mass to get a soft evergreen screen or a tall ground cover. Plant ‘Noelli’ on a hillside or bank to get slope stability as a tasteful solution for a difficult garden spot. It thrives in containers.
Planting notes. Plant ‘Noellii’ in full sunlight and supply moderate water when it’s young. It’s not one of the most drought-tolerant grevilleas, but its heat tolerance, coastal endurance and elastic demeanor make to get an easy-care plant.
Much like other plants in the Proteaceae family, plant grevillea in well-draining, acidic soil with reduced levels of phosphorus. Although it is coastal tolerant, it is also sensitive to elevated levels of salt in the soil.
