A small to medium size evergreen shrub with an upright mounding habit, 4-6 ft. tall and as wide. Foliage has an open and airy quality that is comprised of 6-8 in. long bipinnately divided bright green leaves. Large red and pink flowers grow in 4-5 in. long terminal racemes and hang gracefully from stems. Flowering is most intense from late spring through summer, but can occur intermittently all year.

The Robyn Gordon grevillea cultivar is a graceful mounding shrub. It prefers well-drained soils, sun to partial shade and regular supplemental water during winter and spring. Established plants do well with reduced summer moisture. It is commonly selected as an accent color plant in small gardens and background spaces.

Water Needs

Robyn Gordon grevillea grows best in sunny garden locations on well drained soils and with low amounts of supplemental water during summer. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; more moisture during spring helps achieve a more robust and longer flowering cycle.
