Grevillea x ‘Citrus Sparklepie’

Grevilleas are interesting in that almost all species will cross and you can end up with some really weird shit. In this instance I selected  this mounding evergreen shrub for the vividness of its orange flowers and superior cold hardiness from about 50 others. This cross between G. victorae and G. juniperina has thicker leaves than most cultivars (and seedlings) and that translates directly to improved cold hardiness and they end in a sharp tip. This variety has weathered 10ºF so far and could be hardier.  Larger, vivid orange flowers with a style stained melon red that quickly matches the orange of the perianth. (Pouch like petals that reflex when open). To 3′ tall x 8′ wide in 5 years. Full sun to very light shade in average to poor soil. Water weekly after planting and then as growth increases limit it to once a month- a deep soak. Blooms almost continually with a crescendo in late winter/early spring. Loved by hummingbirds, European honeybees, and native hover flies. Easy to grow. Mulch after planting. Its important that Grevilleas become well established by their first winter- this immediately increases cold hardiness. Once established its fairly care free except for occasional pruning. Established shrubs can go through summer without any supplemental water. Fun to grow shrub. Excellent at the Oregon coast, tolerates sandy substrates with additional water. Not bothered by deer. Elk? I have no idea- they will at least step on it so protect. Grevilleas all require good air circulation. Avoid plants that flop or lay on them- not only will it block the sun  it can even encourage rot. Site your Grevilleas where they are open and the wind can blow them dry.
