Members of the Ammobium genus are native to Australia. Perhaps the best known species is Ammobium alatum, which is commonly known as the Winged Everlasting and is named after its winged stems.
As a member of the Aster family, the flowers bloom in the summer and consist white ray florets with a central disc of yellow or orange. The foliage is silvery in colour.
It makes a nice plant to grow in a wildlife garden as it can help to attract butterflies, hoverflies, and bees. That said it is more often grown for its use as a dried flower and for floral arrangements.
It also makes an attractive rockery plant and looks great when planted in mass.

Like Winged Everlasting, the Yass Daisy (Ammobium craspedioides) has basal rosette leaves. These are spoon shaped and are about 5 inches (12.5 cm) in length. The stems have narrow wings along their edges. Flower heads are button shaped and solitary atop stems that reach about 2 feet (60 cm) in height.
In its native Australia it is often found growing besides Eucalypts plants. The Yass Daisy is naturally found in forests; and enjoys both moist and dry soils.
The common names for the Hardy perennial Ammobium include Winged everlasting. They typically bloom in the summer to early autumn.
Ammobium are fairly large plants that can grow from 60 to 150 cm in height. They have white flowers with a yellow/orange center, and makes an ideal plant for growing in borders.
It is best to sow Winged everlasting on the soil surface then sprinkle with soil, with a spacing of 25 to 40 cm in the early spring or autumn.
Ammobium prefers full sunlight. The soil should be well drained. Ammobium requires between 10 days and 20 days to germinate, when growing indoors it is best to start seeds off 6 to 7 weeks before planting out in mid-spring, they germinate best at a temperature of 15 degrees centigrade.
Winged everlasting require watering in the driest periods of summer.
