Grevillea 'Kings Celebration' PP27,899 - A medium size spreading shrub to 5 to 6 feet tall by 6 to 8 feet wide with brown stems and dark green fine textured dissected leaves. Nearly year-round appear the 5 inch long toothbrush type flower flowers that emerge from whitish buds along the upper side of the inflorescence. Plant in full sun in a well-drained soil and give infrequent to occasional irrigation. Our experience with other grevillea is avoid fertilizers that contain phosphorus and to keep an eye on foliage color for signs of chlorosis that can be treated with acidifying agents or chelated iron. This plant should prove hardy to 20-25 F. This is a tough and drought resistant plant that should be well-adapted to coastal California and adjacent inland areas. Use a specimen, barrier or hedging plant on slopes and banks. The multicolored flowers are striking and attractive to both hummingbirds and bees. We began trialing this cultivar Grevillea 'Kings Fire' and Grevillea 'Kings Rainbow' in 2015 and noted through the trial period that these plants are strong performers with very attractive foliage and flowers. 'Kings Rainbow' has a unique bicolored flower but is the less vigorous plant in the series. In 2019 another very attractive cultivar, Grevillea 'Spirit of ANZAC', with larger bicolored flowers and grey-green foliage has been added to the collection. These cultivars are the result of a breeding program conducted by Digby Growns at Plant Development at Kings Park and Botanic Garden in Perth, Western Australia. The objective of the breeding program was the development of Grevillea cultivars that have large inflorescences with attractive colors. This series made its debut in North America through Ball Horticulture & Star Roses & Plants in 2016 and described as having "exotic looking blooms that flower year-round in Southern California. 'Kings Celebration' is a hybrid that resulted in 2008 from crossing Grevillea fastigiata as the female seed parent with the male pollen parent Grevillea 'Kay Williams', itself a hybrid between G. 'Sandra Gordon' (an old hybrid between G. sessilis and G. pteridifolia) and G. banksii. It displays characteristics of its parentage with its bloom color coming from the seed parent and the vigorous growth and upright growth habit from its pollen parent. It received US Plant Patent PP27,899 in April 2017.  Information displayed on this page about  Grevillea 'Kings Celebration' PP27,899 is based on the research conducted about it in our library and from reliable online resources. We also note those observations we have made of this plant as it grows in the nursery's garden and in other gardens, as well how crops have performed in our nursery field. We will incorporate comments we receive from others, and welcome to hear from anyone who may have additional information, particularly if they share any cultural information that would aid others in growing it.
