Libertia chilensis
Libertia chilensis is a clump-forming, evergreen perennial grown for its elegant, grass-like foliage and charming white flowers in late spring and early summer. Native to South America, it brings a fresh, architectural quality to gardens, making it a fantastic choice for contemporary borders, wildlife planting, and low-maintenance spaces.

Simple Elegance with Seasonal Flowers
Libertia chilensis produces delicate, three-petalled white flowers with golden centres held on slender, upright stems above its fountain of foliage. Blooming in late spring to early summer, the flowers are followed by decorative seed capsules that add interest later in the season. Its clean, linear form suits both naturalistic and formal planting schemes.
Architectural Foliage Year-Round
The evergreen, sword-shaped leaves form a tidy clump that provides year-round texture and movement. Its grass-like habit makes it ideal for adding structure to borders, planting in groups, or softening hard edges in modern or coastal gardens. It also works beautifully when used to contrast against broader-leaved plants.
Great for Wildlife Gardens
While Libertia chilensis is not heavily scented, its open flowers attract pollinators such as bees, and its seed capsules can offer seasonal interest for birds and other garden wildlife.
Growing Tips
Watering: Water well during dry spells in the first year. Once established, it is drought tolerant and only needs occasional watering.
Feeding: Apply a balanced, general-purpose fertiliser in spring to encourage healthy growth and flowering.
Pruning: Remove spent flower stems and any damaged or old foliage in late summer to keep the plant looking tidy.
Dividing: Divide clumps every 3–4 years in early spring to maintain vigour and manage size.
Positioning: Best grown in full sun, though it will tolerate light shade. Ensure good drainage to avoid winter root rot.
Potted: Yes, Libertia chilensis is well-suited to container growing. Choose a medium to large pot with good drainage holes and use a loam-based compost (e.g. John Innes No. 2) mixed with grit or sand for improved drainage. Ideal for patios, courtyards, or contemporary spaces, where its upright habit and year-round form can be enjoyed up close.
Hardy and Low Maintenance
Rated RHS H3, Libertia chilensis is hardy throughout most of the UK. In colder or more exposed areas, a winter mulch or sheltered spot will help protect roots from harsh frosts. It requires little maintenance once settled in and is generally resistant to pests and diseases.
Perfect Companions
Pair Libertia chilensis with:
-
Verbena bonariensis – for airy height and pollinator support
-
Stipa tenuissima – for textural contrast and soft movement
-
Salvia nemorosa ‘Caradonna’ – for deep purple flower spikes
-
Eryngium planum – for sculptural form and drought resistance

Buying Perennials from Jacksons Nurseries
At Jacksons Nurseries we lightly trim back our perennials after flowering and trim them back at the end of the season to ensure that the plants remain neat and tidy whilst in the pot. The more tender the plant the less we cut back to help protect exposed stems from winter frost. Depending on the plant variety we will then prune back further in spring once the risk of the more severe frosts is over.
As a result, depending on the time of year you buy perennials, they may not look like images showing their ‘prime time’ in flower and looking at their best.
From late autumn onwards and dependent on variety, there may be very little visible above the soil except for a few cut back dormant leaves or stems. It is perfectly normal for dormant plants to look like this from autumn onwards, they will however burst back into life in spring.

Perennials are described and classified differently by different gardeners but all would agree that they are plants that come into flower every year from early spring to late summer, the exact time dependent on variety and most die back to ground level in autumn and winter.
As for all plants, soil preparation is time well spent. Dig over the area to be planted ensuring that the ground is free draining. If not then you may wish to either consider planting in a different spot or raising the level of the planting area by adding additional topsoil, well rotted garden compost and/or well rotted manure. Add ‘Fish, Blood and Bone’ fertiliser or a high potash fertiliser to encourage good root growth and development.
It’s always a good idea to plant a few of the same plant together, we recommend planting in 3’s or 5’s to provide a bold effect but allowing them plenty of room to develop.
Always check eventual plant heights when planning borders to ensure that the taller plants are at the back (or at the centre of an island bed) followed by the medium and then smaller low growing plants.
Remember to deadhead perennials after flowering, trim back lightly in autumn as required to tidy the border and if necessary trim again in spring once the risk of heavy frost has passed.
If perennials get too big, start to flower less and less or if it seems to be dying off from the centre, consider dividing the plant but always check that the particular variety is happy to be divided and that you divide at the right time of year for the plant.
By using this simple guide and a little time, perennials can make an absolutely spectacular difference to your garden.
