Grevillea 'Kings Fire' PP27,875 - A medium size spreading shrub to 5 to 6 feet tall with white stems and soft gray-green dissected leaves. Nearly year-round appear the 5 inch long toothbrush type flower flowers that emerge from whitish buds along the upper side (secund) of the inflorescence. The individual flowers emerge first with the recurved styles a deep red color but lightning to orange-red as they straighten with shorter stamen bearing tepals remaining a dark red - very attractive! Plant in full sun in a well-drained soil and give infrequent to occasional irrigation. This plant should prove hardy to 20-25 F. One parent is of coastal origins and this plant may prove itself a good candidate for near the seashore, but this has yet to be proven. We began trialing Grevillea 'Kings Fire' t and Grevillea 'Kings Rainbow' in 2015 for Ball Horticulture and note that both plants are strong performers with very attractive foliage and flowers. Of the two, Grevillea 'Kings Fire' is much more vigorous and has softer foliage and while both have a long blooming season, it seems to bloom heavier and over a longer period - we rarely see it without some flowers! These cultivars both 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. Both varieties are making their debut in North America through Ball Horticulture/Star Roses & Plants. In the Star Roses & Plants 2016 catalog the description of this plant is that it grows to "5 to 6 feet tall with a spreading habit and deep green leaves. It has exotic looking blooms that flower year-round in Southern California. Its tough, durable, drought tolerant and has lots of textured color. Plant in full sun. Hardiness Zones 8,9,10,11" (we actually suspect this USDA rating of 8 perhaps too low). 'Kings Fire' does great in containers or in the landscape and is a favorite of hummingbirds." Given our experience with other similar Grevillea we speculate that this plant will perform best in a well-drained soil with occasional to infrequent irrigation and likely will be best to avoid applications of fertilizer containing phosphorus. 'King's Fire' is the result of crossing in March 2011 of a selected form of Grevillea nivea as the seed parent with Grevillea 'Crowning Glory', a plant also known as 'Lasseter's Gold'. 'Crowning Glory' is reported to be a hybrid between Grevillea formosa and G. 'Honey Gem', itself a garden hybrid thought perhaps to be a cross between G. pteridifolia and a red form of G. banksii. Grevillea nivea is a fairly recently described species that was separated from the Grevillea tetragonoloba complex in 2009 and prior to this it was called Grevillea tetragonoloba "Race B" or referred to as Grevillea 'Scarlet King'. It is known to be a moderately vigorous semi-upright growing plant with red-colored flowers while the pollen parent 'Crowning Glory' has a trailing habit and medium yellow-colored flowers. 'King's Fire was selected as the only seedling grown from this cross in March 2012. It received US Plant Patent PP27,875 in April 2016. This cultivar was released in Australia in 2016 (after the US release) under the name Grevillea 'Scarlet Moon' - information about this Australian release can be found on the website of the Friends of Kings Park  This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Grevillea 'Kings Fire' PP27,875.
