Kunzea ambigua, commonly known as white kunzea, poverty bush or tick bush, is a plant in the myrtle family, Myrtaceae and is found mainly on sandstone soils in eastern Australia. Growing up to 5 m (16 ft) high and wide, it bears small white flowers in spring. Used in native gardening, it attracts native insects. It is also used in amenities planting and sand dune stabilization.
Kunzea ambigua is a small- to medium-sized spreading shrub that may reach 5 m (16 ft) both in height and width, though is usually much smaller (from 1 m (3 ft)). Its bark is fibrous and furrowed, while the narrow lanceolate green leaves are 0.5–1.3 cm in length and 0.2 cm wide, with hairy new growth. Occurring from September to December or January, the white flowers are 1.2 cm in diameter and sweetly fragrant. The stamens are longer than the petals. The flowers are followed by small woody capsules 0.4 cm in diameter.[1][2]
Kunzea ambigua was first formally described in 1797 by James Edward Smith who gave it the name Leptospermum ambiguum.[3] English botanist George Claridge Druce gave it its current binomial name in 1917.[4] The generic name honours German naturalist Gustav Kunze,[5] while the specific epithet is derived from the Latin adjective ambiguus meaning "doubtful" or "uncertain".[6] Its common names are white kunzea and tick bush.
A pale pink-flowered hybrid with Kunzea capitata has been recorded from Stony Range Flora reserve in Dee Why in Sydney's northern beaches region.[7]
Kunzea ambigua is found from northeastern New South Wales, having been recorded in the Grand High Tops of the Warrumbungle National Park,[2] through Victoria and into Tasmania. It grows on sandy soils in coastal or near-coastal regions.[1] It is a very common dry forest shrub of the Sydney region, and regenerates in disturbed or cleared areas.[8] It is associated with scrub she-oak (Allocasuarina distyla), Melaleuca nodosa, cheese tree (Glochidion ferdinandi) in heath or scrub, and with red bloodwood (Corymbia gummifera), peppermint gum (Eucalyptus piperita), forest red gum (Eucalyptus tereticornis), woolybutt (E. longifolia), thin-leaved stringybark (E. eugenioides), and white feather honeymyrtle (Melaleuca decora) in forested areas. In Wilsons Promontory in Victoria, Kunzea ambigua is the dominant species within scattered areas of treeless heath that occur on granite hills and mountains.[9]
In recent times, it has been discovered that the Kunzea ambigua plant grows abundantly in Flinders Island and North East Tasmania. Tasmania regularly experiences strong westerly winds and a high annual rainfall of over 700mm. This harsh, windy and brisk climate is the ideal environment for the Kunzea ambigua plant to thrive.[10]
Insects are the main pollinators of Kunzea ambigua; these include various types of beetles including jewel beetles (Buprestidae), scarab beetles (Scarabaeidae), flower beetles (Mordellidae), and checkered beetles (Cleridae)[11] as well as butterflies, flies, bees and wasps.[12] The tick bush is killed by fire and regenerates from seed. Plants can also colonise unburnt sites with ample sunlight.[12]
It was one of the first species of Australian plant introduced into cultivation in England.[5] It is a hardy and adaptable plant that is used in windbreaks and sand dune stabilization plantings,[1] as well as gardens, particularly in Australian gardens using native plants according to principles of natural landscaping. The species attracts Australian native insects,[13] and can provide shelter for small birds and the long-nosed bandicoot (Perameles nasuta).[14]
It can regenerate quickly after disturbance, suggesting it may have weedy potential if planted outside its natural range.[1]
Kunzea ambigua is registered with the Therapeutic Goods Administration for use in "Kunzea Pain Relief Cream"[15] and "Vita Future Nasal Congestion Relief".[16]

Kunzea ambigua, connue parfois sous le nom de Kunzea blanche, est un arbuste de la famille des Myrtaceae poussant sur les sols gréseux de l'est de l'Australie. Arbuste pouvant atteindre 5 m de hauteur sur autant de largeur, il porte de petites fleurs blanches au printemps. Dans les jardins, Kunzea ambigua attire les insectes. Elle est également utilisée dans les plantations pour la stabilisation des dunes de sable.
Elle a d'abord été appelée Leptospermum ambiguum par James Edward Smith, avant que le botaniste anglais George Claridge Druce ne lui donne son nom actuel en 1917. Le nom de genre honore le naturaliste allemand Gustav Kunze et son nom d'espèce est dérivé du latin ambiguus qui veut dire «douteux» ou «incertain».
Kunzea ambigua est un arbuste de taille petite à moyenne pouvant atteindre 5 m en hauteur et en largeur, mais il est généralement beaucoup plus petit (1 m). Son écorce est fibreuse et sillonnée, tandis que ses feuilles vertes étroites et lancéolées font 0,5 à 1,3 cm de longueur et 0,2 cm de largeur. Apparaissant de septembre à décembre ou janvier, les fleurs blanches font 1,2 cm de diamètre et sont légèrement parfumées. Les étamines sont plus longues que les pétales. Les fleurs sont suivies par de petites capsules ligneuses de 0,4 cm de diamètre.
Kunzea ambigua pousse depuis le nord-est de la Nouvelle-Galles du Sud jusqu'au Victoria et en Tasmanie. Il pousse sur des sols grèseux dans les zones côtières. Il est très commun dans les forêts sèches de la région de Sydney. Il est associé à Allocasuarina distyla, Melaleuca nodosa, Glochidion ferdinandi dans les zones de broussailles et avec Corymbia gummifera, Eucalyptus piperita, Eucalyptus tereticornis, Eucalyptus longifolia, Eucalyptus eugenioides et Melaleuca decora dans les régions forestières.
Les insectes sont les principaux agents pollinisateurs de Kunzea ambigua. On trouve ainsi différentes familles de coléoptères comme les Buprestidae, les Scarabaeidae, les Mordellidae et les Cleridae mais aussi les papillons, les mouches, les abeilles et les guêpes.
Elle a été une des premières espèces de plantes australiennes à être cultivée en Angleterre. C'est une plante robuste et facilement adaptable qui est utilisée comme brise-vent et pour la stabilisation des dunes de sable. En Australie, elle est cultivée dans les jardins, en particulier les jardins australiens à paysage naturel. L'espèce attire les insectes et peut fournir un abri aux petits oiseaux et au péramèle nason (Perameles nasuta).
Elle peut repousser rapidement après une perturbation, laissant à penser qu'elle a un potentiel envahissant en dehors de son aire de répartition naturelle.

Tik-tak grm (bijela kunzeja, lat. Kunzea ambigua), grm iz roda kunzeja, porodica mirtovki. Raširen je po jugoistočnoj Australiji (Victoria, Tasmanija i Novi Južni Wales) gdje često formira šikaru.
Naraste do dva, tri metra visine, a u botaničkim vrtovima i više. Ima sitne listove na kratkim peteljkama. Kapsule sjemena podijeljene su na nekoliko odjeljaka, a na drvetu ostaju samo dok plod ne sazrije. Atraktivan je za ptice i kukce.[1]
