Lilly Pilly trees ( Syzygium smithii ), with their vibrant new growth and edible berries, are a popular choice for gardens. This guide covers everything you need to know about identifying, growing, and incorporating them into your landscape. Whether you’re a seasoned gardener or just starting out, we’ll explore the world of Lilly Pillys, from selecting the right variety to troubleshooting potential problems.
The Lilly Pilly is an evergreen tree recognizable by its rough bark and crown of lush, creamy-green leaves. New growth often emerges in striking shades of pink or red. In summer, fluffy, creamy-white flowers appear, later developing into the namesake Lilly Pilly berries. These edible berries, ranging in color from white to deep maroon, ripen in winter, providing a feast for birds and a splash of color to your garden.
Cultivating the Lilly Pilly
Growing Lilly Pillys successfully involves replicating their natural rainforest habitat. They thrive in well-drained, moisture-retaining soil and prefer partial shade, particularly during hot summers. Regular watering is crucial, especially during dry periods, but avoid overwatering. Aim for deep, infrequent watering, allowing the soil to dry out slightly between sessions.
Landscaping with Syzygium smithii
The versatility of the Lilly Pilly shines in landscaping. Its dense foliage makes it ideal for privacy screens, while its vibrant colors and graceful form create a stunning specimen plant. It also responds well to pruning, making it suitable for hedges. Whether you’re looking for a natural screen or a striking focal point, the Lilly Pilly offers many possibilities.

Can You Grow Lilly Pilly in the UK?
Growing Lilly Pilly in the UK presents unique challenges due to the cooler, wetter climate. Success depends on understanding their needs and adapting your approach.
Mimicking Australian Sunshine
Lilly Pillys require ample sunlight. A south-facing, sheltered wall can create a warm microclimate, maximizing sun exposure. Courtyards or greenhouses may also provide the necessary warmth, especially during winter.
Winterizing Your Lilly Pilly
Protecting Lilly Pillys from harsh UK winters is essential. Horticultural fleece provides insulation, while a thick layer of mulch protects the roots. For younger or more delicate varieties, consider moving them indoors to a bright conservatory or heated greenhouse.
Choosing the Right Variety
Not all Lilly Pillys are equally cold-hardy. Research and select varieties known for their tolerance to cooler temperatures. Specialist nurseries or online gardening forums can provide valuable guidance.
Essential Care
Well-drained, slightly acidic to neutral soil, rich in organic matter, is ideal for Lilly Pillys. Regular watering, avoiding overwatering, is crucial. Pruning promotes bushier growth and enhances their appearance.
The Rewards
While UK-grown Lilly Pillys may not fruit as abundantly as their Australian counterparts, their fragrant flowers and vibrant foliage add exotic beauty to any garden.

How Big Does a Syzygium Smithii Grow?
The size of a Lilly Pilly depends on several factors: genetics, growing conditions, and pruning. In a garden setting, they typically reach 8-10 meters. In their native Australian rainforests, they can grow up to 30 meters.
Factors influencing size include sunlight, soil quality, and watering. Pruning plays a significant role, allowing you to control size and shape. The chosen cultivar also influences growth habits, with some being naturally more compact.
In the wild, a more typical mature size is around 20 meters with a trunk diameter up to 70cm. Regular pruning is key for maintaining a compact, hedge-like shape. Less frequent pruning creates a more natural, tree-like form. Ongoing research suggests environmental factors, like strong winds, may also influence growth.
Can You Eat Lilly Pilly Berries?
Most Lilly Pilly berries are safe to eat, with flavors ranging from sweet to tart. The Syzygium australe (Creek Lilly Pilly) and Syzygium luehmannii (Riberry) are known for their pleasant taste. Ensure berries are ripe before consumption, as unripe fruit can cause stomach upset. They are versatile ingredients for jams, jellies, sauces, and beverages. Rich in antioxidants, they are considered a potential superfood.
With over 60 species native to Australia, flavor profiles vary widely. From traditional bush tucker to modern gourmet treats, Lilly Pilly berries offer a unique culinary experience. Their versatility extends to various culinary creations, and their antioxidant content suggests potential health benefits.
Identifying ripe berries is key – look for vibrant, species-specific colors. Unripe berries can cause digestive discomfort. Each species offers a distinct flavor, from the sweet Creek Lilly Pilly to the tarter Riberry. While most are safe to eat when ripe, some have less appealing flavors.
Exercise caution when foraging for wild edibles. Proper identification is crucial to avoid toxic look-alikes. Consult a reliable guide or expert before consuming any wild berries.
