Did you know that some of the plants we always thought were native to Australia are actually from Southern Africa?
An Introduction to the Asparagaceae Plant Family
Welcome to the fascinating world of the Asparagaceae family, a diverse group of plants that includes everything from the decorative agave to the edible asparagus.
This family of plants is as unique as it is varied, offering a myriad of shapes, sizes and uses, making it a favourite amongst gardeners, landscape architects, and plant enthusiasts alike.

The Asparagaceae Plant Family: A Closer Look
The Asparagaceae family stands out due to its distinctive characteristics. Many members of this family are known for their hardiness and ability to withstand harsh conditions that other plants might struggle with. They often long, slender leaves and impressive flower spikes.
The flowers can be difficult to distinguish from lily family members (Liliaceae) which share the same six tepals (three petals and three sepals that look alike), six stamens and three-parted pistil. Their flowers do not form an umbel like those in Amaryllidaceae.
Unfortunately, there isn’t an easy way to differentiate plants in this family from other look-alikes.
Key genera in Asparagaceae include lomandras, liriope, yucca, agave, and asparagus, each with its unique attributes and qualities.
Identifying Plants in the Asparagaceae Family
Identifying plants within the Asparagaceae family involves close observation of various plant parts:
- Roots: Plants in the Asparagaceae family usually have fibrous roots typical of monocots, but they don’t have bulbs. Many Liliaceae (lily) and Amaryllidaceae (onion) family members have bulbs which would rule them out of the asparagus family.
- Stems: Plants in this family generally have semi-woody stems, as in the case of yuccas, or they’re strappy plants with a rhizome, as with lomandras and liriopes. Agaves are a bit of column A and a bit from column B.
- Leaves: Asparagaceae plants typically have “leaves” arranged in rosettes. Technically “cladodes”, they are in fact modified stems rather than true leaves. The shape is often linear or lanceolate in shape.
- Flowers, fruits, and seeds: Asparagaceae flowers often have six tepals (three petals and three sepals that look alike), six stamens, and a three-chambered ovary. The flowers are usually small and in clusters, but don’t form an umbel. The fruit is typically a berry or a capsule.
Remember that there can be exceptions within each family. Consulting a botanical key or guide can provide more precise identification.

Exploring the Asparagaceae Genera
Lomandra
Lomandra can be recognised for its long, fibrous, grass-like strappy leaves. It boasts flower spikes in shades of yellow or white, which are sometimes fragrant. This hardy plant can withstand harsh conditions, making it a popular choice in Australian landscapes.
Liriope
Liriope is a genus known for its clumping growth habit and small flower spikes, often purple or white, which bring a splash of colour. Liriopes are particularly great as ground cover or along borders, especially in shady areas where plant palettes are limited.
Yucca
Yucca plants are easily identifiable by their thick, sword-like leaves and towering flower spikes. They offer architectural interest with their distinctive silhouette, providing a sculptural element to the garden. Just don’t plant them along footpaths where the leaves can poke people in the eye.
Agave
Agave plants are beloved for their rosettes of thick, fleshy leaves, sometimes edged with spines. Their dramatic forms and low water needs make them a highly prized option for dry, arid gardens, where they can truly shine.
Asparagus
The Asparagus genus can be distinguished by its shoots, feathery foliage and red berries. There are ornamental and edible varieties of asparagus. The new shoots in Spring are harvested on the edible crops, which you can see reflected in the new growth of ornamental varieties.
Why Choose Asparagaceae Plants?
In Australia, these plants are widely used in xeriscaping (water-saving gardens). Some varieties of lomandra can even tolerate wet feet as well, especially some L. hystrix varieties.
They also provide a range of aesthetic options to suit different garden styles, from the desert vibes of yuccas to the scrubby bush vibes of lomandra.
Daniel’s Wrap
The Asparagaceae plant family is as diverse as it is beautiful. With so much to offer, these plants are well worth further exploration and appreciation. Whether you’re an experienced gardener or a professional landscaper, the Asparagaceae family has something to offer everyone.
