Learn About Your New Banksia integrifolia 'Sentinel'
Banksia integrifolia 'Sentinel' is a compact, upright form of the Australian native Coast Banksia, specifically bred for narrow spaces, urban landscapes, and smaller gardens. Growing to just 2–3 metres tall and 1–1.5 metres wide, Banksia integrifolia 'Sentinel' retains all the key features of the species — silvery-green foliage, tough texture, and bold yellow flower spikes — in a more contained, structured form.
Flowering from late summer through winter, this cultivar provides colour and seasonal interest during the cooler months while attracting birds and pollinators. Its dense growth habit and low maintenance needs make it ideal for screening, feature planting, and tight spaces where height is needed without excessive bulk.
Banksia integrifolia 'Sentinel' performs well in coastal conditions, adapts to a variety of soils, and thrives in full sun to part shade. It’s a strong option for modern residential projects, courtyards, and commercial landscapes that need a resilient, native feature with year-round visual appeal.

Watering Requirements After Planting Your Banksia integrifolia 'Sentinel'
When planting a new tree or shrub, proper watering is essential to ensure healthy establishment and long-term growth. Follow these guidelines to give your plant the best start:
- Immediately After Planting:
Water generously right after planting to settle the soil around the roots and eliminate air pockets. This helps the roots make good contact with the soil. - First Three Months (Establishment Phase):
The initial three months are critical for root development. Water deeply twice daily (morning and evening) to encourage strong, deep root growth. - Irrigation Systems:
If using an irrigation system, adjust it to provide adequate water during the establishment phase. Ensure the water reaches the root zone without overwatering. - Weather Considerations:
Adjust watering based on weather conditions. Increase frequency during hot, dry periods and reduce it during cooler, wetter seasons. - Ongoing Care:
After the establishment phase, gradually reduce watering frequency but ensure the plant receives consistent moisture, especially during dry spells.
By providing consistent and appropriate watering during the initial months, you’ll help your new tree or shrub establish a strong root system and thrive in your garden.
