Boronia megastigma

Brown Boronia (Boronia megastigma) is grown for one thing above all others, and that is the perfume. A slender shrub to about 1.5m tall and 1m wide, it covers itself in small nodding bells in late winter and spring, chocolate brown on the outside and clear yellow within. The scent carries several metres on a still morning, so it belongs beside a door, a path or a seat rather than at the back of a bed.

Why you'll love it

• The strongest perfume of any Australian native. A single plant in flower scents a whole courtyard, and cut stems do the same indoors.
• Flowers with unusual colouring. Deep brown cups that open to show yellow inside, quite unlike anything else in a native garden.
• Fits a small garden. At 1.5m by 1m it slots into a narrow bed or a pot without crowding its neighbours.
• Works for bees and butterflies. A Western Australian native whose flowers open early in the season, when forage is scarce.

Where it works best

Pots and containers. The easiest way to grow it well, because you control the drainage and the mix. Use a 300mm or larger pot and stand it where you walk past daily.

Borders and edging in small gardens. Plant 80cm apart through a front border for a soft informal run. Give each plant a cool root zone rather than baking soil.

Feature planting. One plant beside an entry or an outdoor seat earns its place for the six to eight weeks it is in flower.

Growing Brown Boronia in Australia

Position and climate. Morning sun with shade through the hottest part of the afternoon is the sweet spot. It suits warm temperate, cool temperate and Mediterranean gardens, and takes light frost only. Humid subtropical and tropical summers are its undoing, so treat it as a pot plant in a sheltered airy spot there.

Soil. Sharp drainage with roots that stay cool and evenly moist, which sounds contradictory but simply means a gritty, slightly acidic mix under a thick mulch. Never plant into heavy clay without raising the bed.

Water and feed. Consistency is everything. One hot day of complete dryness can kill an otherwise healthy plant, so check pots daily in summer. Feed lightly with a low phosphorus native fertiliser once flowering finishes.

Pruning. Trim by about a third immediately after flowering, cutting into leafy wood. This single job keeps the plant compact and adds years to its life. Be realistic: even well grown boronias are short lived, and three to five years is a normal span.

What to expect when it arrives

It is grown in tube and in 140mm pots sold in packs of 10. Both are young plants, well rooted but not yet in bud, and they establish faster than an older boronia would. The 140mm pack suits a border run or matched pots.

Plants are delivered Australia wide, with delivery from $29.95. Expect a settling in period of two to three weeks, then steady growth and first flowers the following winter. Every plant is covered by our 30 day healthy plant guarantee.

Common questions

Why did my boronia die suddenly?

Nearly always water, in one direction or the other. A pot that dried out for a day, or a bed that stayed wet after rain, will finish it quickly. Even moisture over sharp drainage is the trick.

How long will it live?

Three to five years is typical, and a well pruned plant in a pot can push past that. Treat it as a superb short term performer rather than a permanent shrub.

Can I grow it in a pot?

Yes, and most gardeners get better results that way. A 300mm pot of free draining native mix, morning sun, and daily checking through summer will outperform an average garden bed.
