Freesia leichtlinii hybrid

Synonyms - Freesia leichtlinii, Freesia refracta.

Most naturalised plants are hybrids between Freesia alba and Freesia leichtlinii from horticultural stocks.

Order - Liliales

Family - Iridaceae


Freesia is from the


Other Names:


Freesias are tufted plants with soft, light green, sword shaped basal leaves arising annually in a fan like arrangement from an underground corm. The erect flowering stem is bent to one side just below the lowest flower and has white or cream to yellow flowers which often have yellow to orange markings. The outside of the flower is usually flushed with purple. The 3-8 flowers are all arranged on one side of the flower stalk. The strongly sweet-scented flowers are tubular and 6-lobed. Each flower has 3 stamens and a slender 6-branched style. Bulbils are produced in the lower leaf axils. Freesia is a horticultural hybrid, originally from South Africa, but is now a serious bushland weed occurring in a variety of disturbed habitats. It flowers in spring.





Arranged like a fan.

Stipules - None

Petiole - None

Blade - Soft, flat, narrowly oval to narrowly egg shaped, 50-350 mm long by 4-8 (-12) mm wide. Green on both sides. Mid veins prominent


Flower stem - Erect, wiry, 100-400 mm tall by 1-4 mm diameter, bent just below the lowest flower. Occasionally branched.

Flower head:

3-8 flowers in a spike at the end of a stem. Bracts green with translucent edges, occasionally tinged with purple. Outer bract 10-15 mm long.


Sweetly aromatic, tubular with 6 petals and cream to white with a yellow blotch and purple flushes on the outside.

Ovary -

Perianth - Tubular, 2 lipped, white cream or yellow, usually with purple blushes on the outside. Tube 30-45 mm long with a narrow lower section 10-20 mm long and a funnel shaped upper section with lobes of differing sizes. Lower lobes often have orange to yellow blotches. Upper lobe or the inner ring is oval to egg shaped, usually hooded and 15-20 mm long by 12-15 mm wide.

Stamens -

Anthers - Usually white, occasionally purple, 6 mm long.


Cylindrical capsule, 10-15 mm long with a minutely rough surface. Contains many seeds.



Bulbils are produced in the lower leaf axils.


Short and fibrous feeder roots.

Conical corms, 10-15 mm diameter.

Key Characters:

Leaves soft, not fibrous.

Inflorescence unbranched and spike like.

Flowers with 2 floral bracts.

Outer floral bract undivided.

Flowers sessile, secund on a horizontal flexuose axis.

Style branches divided into 2 segments.

Adapted from G. Perry.


Life cycle:

Annual leaves emerge in autumn with flowering and seed set in spring. Bulbils are produced in lower leaf axils in spring. Top growth dies off over summer and the plant survives on a perennial corms.



By seeds, bulbils and corms.

Flowering times:

August to October in Perth.

Spring in WA.

September to October in SE Australia.

Seed Biology and Germination:

Vegetative Propagules:



WA plants are a hybrid of 2 South African species.


Population Dynamics and Dispersal:

Spread mainly by intentional planting of corms, earthmoving and dumping of garden refuse.

Seeds and bulbils moved by water flows, slashing and wind also.

Origin and History:

South Africa.

Introduced as a garden plant.



Occurs in the Avon Wheatbelt, Esperance Plains, Jarrah Forest, Mallee and Warren regions of WA.


Tend to be located close to habitation.


Temperate. Mediterranean.


Plant Associations:





Weed of disturbed bushland, coastal heath and granite outcrops.


Not recorded as toxic.



Management and Control:

Mowing or grazing normally provide control. Don't mow after flowering or bulbil formation as this may spread the infestation.

Avoid dumping contaminated garden refuse in or close to bushland.

Avoid moving contaminated soil to clean areas.


Eradication strategies:

These plants are very difficult to control by hand weeding because they produce seed, corms and bulbils. Loosen the soil before removal to prevent the corm breaking off.

Continual grazing or repeated mowing provide eventual control.

2-3 years of spraying with 0.5 g metsulfuron(600g/kg) or 100 g 2,2-DPA(740g/kg) plus 25 mL Pulse® in 10 L water will usually eradicate it. Lower rates of metsulfuron(600g/kg) down to 0.1 g in 10 L water have provided reasonable control in some situations with less damage to native species. Alternatively, 50 mL glyphosate(450g/L) plus 25 mL Pulse® in 10 L water applied in winter or spring before the end of flowering provides good control of existing plants but there is often a subsequent emergence. The area will require spraying again next season to control the tiny seedlings and plants emerging from bulbils.

Painting leaves or wiping with a sponge glove dipped in a mixture of 1 part glyphosate(450g/L) in 2 parts water can be used in sensitive areas.

Replant native shrub species if necessary. Avoid earth works that carry new corms, bulbils and seed into the area. Start control at the top of the catchment to prevent seed and bulbils transported in water reinfesting treated areas. Don't mow or slash after seed or bulbil formation as this may increase spread.
