Beaumont macadamia

Growing in Pots, Balconies & Indoors

Both of the grower’s key facts point the same way: this is not a houseplant, and it is not suited to long-term container growing. The Beaumont macadamia is a full-size evergreen nut tree (3-12 m), best grown in open ground; a pot is only a temporary home for a young seedling.

Quick Details

• Container Size: Not recommended long-term; only a deep nursery pot for a young seedling
• Indoor Suitability: Not a houseplant – a large outdoor tree
• Best Spot: Full sun, in the open ground
• Soil & Drainage: Deep, free-draining soil
• Watering: Regular water while young and establishing

Indoors & On the Windowsill

• Not for indoors: A large tree needing full sun – no room or windowsill will suit it.
• Young plants only under cover: In a climate colder than its range, a seedling can be kept in a pot in a bright, frost-free spot for its first winters, but it must ultimately go in the ground.

On a Balcony or Patio

• Ground, not balcony: This tree isn’t a practical balcony or patio container subject – it needs room to root and spread. Grow it in the garden where the climate allows.
• While young in a pot: keep it in the deepest pot you can, in full sun and sheltered from wind, and move it on before the roots circle.

Choosing the Pot, Soil & Long-Term Care

• Not a long-term pot plant: The grower marks containers as unsuitable. Macadamias make deep roots and a large canopy that a pot cannot support for long. A young seedling can spend its first year or two in a deep pot, but plan to plant it in open ground.
• If you must start it in a pot: use the deepest container you can (to suit the developing taproot), a free-draining mix and strong drainage holes; skip a standing water saucer to avoid root rot; terracotta breathes and dries faster, while glazed or plastic holds moisture longer.
• Feeding & moving on: feed lightly while young and pot on before it becomes root-bound – then transplant to its permanent site.

Bloom & Flower Guide

Quick Details

• Bloom Season: Spring into summer
• Time to First Bloom: Usually four to six years from a young tree; grafted trees flower sooner
• Flower Appearance: Long, slender hanging spikes (racemes) crowded with many small pink flowers
• Edibility: The flower is not eaten; treat the bloom as ornamental (it is the later nut that is the crop)

Detailed Blooming Overview

‘Beaumont’ is a popular macadamia hybrid noted for its distinctly pink flower spikes. In spring and summer it hangs pendent racemes, each strung with dozens of tiny flowers, among the dark, spiny-edged leaves. Only a small fraction of these many flowers will set nuts, but the trees flower heavily and reliably, and the display is a magnet for bees.

Flower Characteristics

• Many small pink flowers packed along slender, hanging racemes.
• Borne in profusion, though only a few per spike develop into nuts.
• Nectar-rich and very attractive to bees.

Bloom Care & Thinning

• Managing the bloom: No thinning is needed; the tree naturally sheds most flowers and retains only a portion as developing nuts.
• For a good set: Cross-pollination with another macadamia nearby improves nut set, though ‘Beaumont’ also sets on its own.
• Pollination: Pollinated by bees, so avoid spraying open flowers to protect the visiting insects.
