Description:

An adaptable shrub that develops a dense, rounded form; grows well in most well drained soils; deep ruby red, spidery flower clusters emerge from late winter to summer, and are good for cutting; shiny, dark green foliage adds great texture

Ornamental Features

Ruby Clusters Grevillea features showy clusters of ruby-red spider-like flowers with rose overtones at the ends of the branches from late winter to late summer. The flowers are excellent for cutting. It has attractive dark green evergreen foliage which emerges coppery-bronze in spring. The glossy narrow leaves are highly ornamental and remain dark green throughout the winter.

Landscape Attributes

Ruby Clusters Grevillea is an open multi-stemmed evergreen shrub with a more or less rounded form. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a relatively low maintenance shrub, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting birds and butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Ruby Clusters Grevillea is recommended for the following landscape applications;

  • Mass Planting
  • Hedges/Screening
  • Rock/Alpine Gardens
  • General Garden Use

Planting & Growing

Ruby Clusters Grevillea will grow to be about 6 feet tall at maturity, with a spread of 6 feet. It has a low canopy, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. This plant should not require much in the way of fertilizing once established, although it may appreciate a shot of general-purpose fertilizer from time to time early in the growing season. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid.
