Agonis flexuosa

The Willow Myrtle is a low-maintenance, drought-hardy Australian native, valued for its weeping form, aromatic foliage, and resilience in tough environments. Ideal for streetscapes, residential gardens, parks, and large-scale landscapes, this evergreen tree thrives in coastal conditions, high winds, poor soils, and extended dry periods, making it a top choice for urban and coastal planting.

Its narrow, lance-shaped leaves are dark green with a silvery underside, releasing a distinct peppermint scent when crushed, adding sensory appeal to any space. In spring and early summer, the tree produces clusters of small white flowers, attracting pollinators and beneficial insects, further enhancing its ecological value. With a graceful, cascading growth habit, the Willow Myrtle provides shade, structure, and movement, making it an exceptional feature tree for low-maintenance and water-wise gardens.

Some description

When you plant a new tree, it's crucial to give it the right start by ensuring it receives sufficient water. Here’s a general guideline for watering your newly planted tree:

• Immediately After Planting: Water your tree generously right after planting your Tristaniopsis laurina 'Luscious' (Watergum) to settle the soil around the roots and eliminate any air pockets.
• First Three Months: The initial three months are critical for the establishment of the tree. During this period, the tree should be hand watered twice daily, in the morning and evening. This helps the roots grow deep and strong.
• Irrigation System: If you have an irrigation system, adjust it to ensure the tree gets adequate water during these first months.
• Adjusting to Weather Conditions: Always consider the weather conditions and adjust your watering accordingly. In hotter and drier periods, additional watering may be necessary.

Consistent attention to your tree’s watering needs during this initial period will help ensure its healthy growth and long-term success in your garden.
