Summary
Xanthorrhoea johnsonii, commonly known as Johnson’s Grass Tree, is a perennial plant native to the sclerophyll forests and heathlands of eastern Australia. It is a slow-growing species that can reach up to 16 feet (5 meters) in height, with a thick, woody trunk and a tuft of long, narrow leaves that can persist for many years. The foliage is often used in floral arrangements due to its durability and unique appearance. Johnson’s Grass Tree produces a tall flower spike that can reach several meters in height, covered in small white to cream flowers that are attractive to a variety of pollinators.
This plant is highly valued for its drought tolerance, fire resistance, and low maintenance requirements, making it a popular choice for xeriscaping and native plant gardens. It thrives in well-drained, sandy soils. Full sun is ideal for optimal growth. In cultivation, it is often used as a focal point in landscapes due to its striking form and texture. While generally disease-free, it can occasionally suffer from root rot if planted in poorly drained soils.CC BY-SA 4.0
