It is an irregularly-branched shrub with bluish-grey leaves and pale-coloured flowers with a long, protruding style. Although comparatively rare in the wild, it is one of the easiest verticordias to propagate and grow in most conditions. DescriptionVerticordia longistylis is a shrub which grows to a height of {{convert|10-70|cm|in|sigfig=1|abbr=on}} and about {{convert|70|cm|in|sigfig=1|abbr=on}} wide. Its leaves are thick, bluish-green, linear in shape, {{convert|4-10|mm|in|sigfig=1|abbr=on}} long and have a blunt end.[1]The flowers are unscented, inconspicuous and scattered, each flower on a spreading stalk {{convert|4-5|mm|in|sigfig=1|abbr=on}} long. The floral cup is hemispherical, {{convert|5|mm|in|sigfig=1|abbr=on}} long, warty and hairy, especially on the lower half. The sepals are yellow and purple {{convert|6-7|mm|in|sigfig=1|abbr=on}} long, and hairy, with two or more especially long, thicker hairs. The petals are a cream to yellowish, egg-shaped, erect and dished, about {{convert|3|mm|in|sigfig=1|abbr=on}} long and their edges are covered with short hairs. The style is {{convert|27-32|mm|in|sigfig=2|abbr=on}} long and straight with a few hairs. Flowering time is from December to June.[1] Taxonomy and namingVerticordia longistylis was first formally described by Alex George in 1991 from a specimen he collected in the Fitzgerald River National Park and the description was published in Nuytsia.[2][3] The specific epithet (longistylis) is derived from the Latin word longus meaning "long"[4]{{rp|494}} and the Ancient Greek stylos meaning "column" or "pillar",[4]{{rp|767}} referring to the unusually long style of this species.[1]George placed this species in Subgenus Verticordia, Section Infuscata along with V. oxylepis.[3] Distribution and habitatThis verticordia grows on exposed spongolite in the Fitzgerald River National Park in the Esperance Plains biogeographic region.[1][5][6] ConservationVerticordia longistylis is classified as "Priority Three" by the Western Australian Government Department of Parks and Wildlife,[5] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[7]Use in horticultureBlue spruce verticordia is readily propagated from cuttings and can be grown in a range of soils, although it is slow growing and more open when grown in sand. Established plants are both frost and drought-hardy but can become straggly if not pruned. The flowers are insignificant except at close range and the bluish foliage is described as "attractive".[1][8] References1. ^1 2 3 4 {{cite book |author1=Elizabeth A.
