Melaleuca nesophila, the Showy Honey Myrtle, is an evergreen Australian native shrub to small tree from the south coast of Western Australia. Fine grey green foliage sits on a dense rounded frame over papery bark, and mauve to pink pom pom flowers cover the outer growth through spring and summer.
Mature width is 2 to 4 metres, with height usually settling around 3 to 5 metres, and growth of 30 to 60 centimetres a year. It wants full sun and takes sand, limestone, gravel and moderately heavy soils. Salt wind, drought and light to moderate frost are all handled once the roots are down.
This is a screening and hedging plant first, used along boundaries, on coastal blocks and through council road reserves where conditions are hard and maintenance budgets are thin. Space it at 1 to 1.5 metres for an informal screen. It gives colour, density and habitat value from one low input plant.
Frequently Asked Questions
About Showy Honey Myrtle
What is Melaleuca nesophila?
Melaleuca nesophila, or Showy Honey Myrtle, is an evergreen Australian native shrub to small tree from southern Western Australia. It has fine grey green foliage, a dense rounded habit and soft papery bark, and carries mauve to pink pom pom flowers through spring and summer that age to a soft grey.
How big does Showy Honey Myrtle grow?
It spreads 2 to 4 metres wide and generally reaches 3 to 5 metres tall in a garden, though regular trimming will hold it lower. Growth is moderate to fast at around 30 to 60 centimetres a year, so a screen planted from advanced stock closes over within three or four seasons.
How far apart should I plant it for a hedge or screen?
For a dense informal screen, plant 1 to 1.5 metres apart. For a tighter formal hedge, bring that in to 80 centimetres. As a feature tree, allow 3 to 4 metres so the full canopy and form can develop, or 3 metres apart along an avenue for a uniform, soft textured line.
Is it suitable for coastal positions?
Yes, it is one of the better coastal Melaleucas. It tolerates salt laden wind, sandy and limestone soils, and exposed front line positions once established, which is why it is planted so widely along the southern coastline. In very exposed sites it will lean with the prevailing wind, and most people like the result.
When does it flower?
The main flush runs through spring and into summer, roughly September to January. Flowers open mauve to purple pink in dense rounded heads across the outer foliage, then age to grey and stay on the plant. Bees and honeyeaters work it heavily while it is out, so expect plenty of activity.
Is it frost tolerant?
It handles light to moderate frost once established, which covers most coastal and near coastal parts of southern Australia. Young plants are more vulnerable in their first winter, so plant in autumn or early spring and keep them out of low frost hollows. Hard, repeated inland frost will burn new growth.
How do I prune and care for Showy Honey Myrtle?
Tip prune after flowering to keep it dense and stop the base going bare. It takes a hard cut back if it becomes leggy, though remove no more than about a third at a time. Water through the first summer, then it is largely self sufficient. Use a low phosphorus native fertiliser in spring on poor soils.
