10 Different Types of Bottlebrush Trees And Shrubs

Overview

Native to Australia, bottlebrush plants are a group of approximately 50 evergreen bushes that get their name because the bristled flowers they produce resemble the kind of brush used to clean the inside of a baby’s bottle. The plants feature cylindrical, bushy-stamened flowers in a range of red, yellow or pink which appears brighter against needle-like, gray- to deep-green foliage.

Drought- and salt-tolerant, these plants are often grown as shrubs but can be grown as a bottlebrush tree, reaching heights of up to 25 feet. Although the blooms don’t have a fragrance, the bottlebrush leaves release a lemony scent when bruised.

While bottlebrush plants are great for attracting hummingbirds and butterflies, they also attract bees, which is great for promoting pollination. Most varieties bloom throughout summer, with flowers tapering off as the growing season draws to a close. Outside of their hardiness zones, bottlebrushes are often grown as house or conservatory specimens.

1. Crimson Bottlebrush (Melaleuca citrina )

Melaleuca citrina, commonly known as common red bottlebrush, crimson bottlebrush is a shrub growing to 5 m (20 ft) tall but more usually in the range 1–3 m (3–10 ft) high and wide, with arching branches clothed with lance-shaped leaves that emerge coppery before maturing to gray-green. The leaves release a lemony scent when bruised.

The plant has hard, fibrous or papery bark and its young growth is usually covered with soft, silky hairs. The flowers are red and arranged in spikes on the ends of branches that continue to grow after flowering and sometimes also in the upper leaf axils. This variety is great for foundations, hedges, wall-side borders, Mediterranean gardens, city gardens or containers.

Melaleuca citrina occurs in near coastal areas of New South Wales, including the Blue Mountains and extends as far west as the Central Western Slopes. It also occurs in the east coast areas of Victoria and grows in swamps and along creeks and rivers.

2. Weeping Bottlebrush (Melaleuca viminalis)

Melaleuca viminalis, commonly known as weeping bottlebrush or creek bottlebrush is a multi-trunked, large shrub or tree with hard bark, often pendulous foliage and large numbers of bright red bottlebrush flowers in spring and summer. It is possibly the most commonly cultivated melaleuca in gardens and its cultivars are often grown in many countries.

The flowers are bright red and are arranged in spikes on and around the ends of branches which continue to grow after flowering. Flowering occurs from September to December and often sporadically throughout the year. Flowering is followed by fruit which are woody capsules. This melaleuca occurs along the eastern part of Queensland from the Cape York Peninsula south to Moree and Grafton in New South Wales.

It is a rather desirable shrub in the Myrtaceae family with striking crimson red (bottle brush-like) flower spikes with darker anthers, produced in late spring to summer.

4. Albany Bottlebrush (Melaleuca glauca)

Melaleuca glauca occurs in the south and south-western coastal districts of Western Australia between Perth and Albany in the Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions, where it grows in swampy ground in sandy or clayey soils.

5. Lemon Bottlebrush (Callistemon citrinus)

The Lemon bottlebrush can be grown as a large shrub or small tree with a mounding habit 15-25 ft. tall, 15-20 ft. wide. Citrus-scented leaves are pointed and 3-4 in. long; new growth emerges soft and reddish before maturing pale green and hard.
