As you might guess there aren’t that many plants beginning with ‘X’, but Xerochrysum is an interesting genus of around 6 or 7 species of short- lived perennials and annuals which are native to open grassland and scrub in Australia.

The stemless lance – like leaves are hairy. The flowers are dasiy like with papery white, yellow or pink bracts and a central disc of, often, yellow florets. The perennials can be used to fill in gaps in herbaceous borders and low – growing cultivars are suitable as edging or for containers.

The name Xerochrysum comes from Greek xeros meaning “dry” and chrysos meaning “gold” (this refers to the common yellow papery bracts that occur within the genus).

X. bracteatum is often grown for its cut and dried flowers and it self seeds freely. Also known as the “Golden Everlasting”, this is one of the best known of the “paper daisies” as it is a very widespread species occurring in both annual and perennial forms. It varies in habit from prostrate to a shrubby plant of about 1m in height. The leaves are usually large (up to 100mm long) and green to grey-green in colour. The individual flowers are very small but are formed into a large cluster surrounded by large papery bracts. The overall appearance is that of a large, single “flower” with the bracts as the “petals”. However, well over a hundred true flowers occur inside the ring of bracts.

The ‘golden everlasting’ has been cultivated for many years and a number of forms have been selected for cultivation. These include several which have resulted from both chance and deliberate hybridisation. Some examples are:

• “Diamond Head” – perennial; green foliage, 0.2m x 0.5m. Yellow flowers

• “Dargan Hill Monarch” – perennial; grey leaves, 0.8m x 1m. Yellow flowers

• “Cockatoo” – perennial; similar to “Dargan Hill Monarch”, pale yellow bracts around a head of small orange flowers

• “Princess of Wales” – perennial; similar to “Dargan Hill Monarch” but more compact (0.6m x 0.6m). Yellow flowers

• “Kimberley Sunset” – perennial; grey leaves, 0.8m x 1m. Pink flowers

In addition, breeding work in Europe and Australia has produced annual forms with an outstanding range of colours – yellow, red, purple, orange. These are excellent for a massed, colourful display. Most forms are suited to cultivation in many areas. The annual forms can be purchased in packets from a number of commercial suppliers and established as instructed on the packs.

Perennial forms are usually quick growing in a sunny, well drained position. They benefit from a regular light pruning annually to encourage branching and a greater number of flowers. Severe pruning to overcome “legginess” may be successful but only as a last resort.

Golden everlasting responds well to annual fertilising, usually with a slow-release type and appreciates an assured water supply. The plants vary in their ability to withstand frost but most are at least moderately frost resistant.

Propagation of X.bracteatum from seed is easy; no pretreatment is required. Propagation from cuttings is also fairly easy and is the only way that named cultivars should be propagated.

Various close ups of X. bracteatum and cultivars

Xerochrysum is half hardy to frost hardy and should be grown in moderately fertile, moist but well-drained soil in full sun. Those cultivars which reach 90 cms or more need staking. They can be propagated from seed in the spring. they might susceptible to downy mildew.

These very popular plants bring long-lasting colour and warmth into the garden. There are many cultivars available in nurseries with flowers varying from white through cream, lemon, canary yellow, gold and bronze. Many of the pink varieties are the result of plant breeding, most probably using South African species as this colour is very uncommon in Australian plants.

They will keep producing flowers particularly if spent flowers are continually removed. Butterflies and other insects love them and will flock to your garden adding another layer of interest. They are also excellent as dried flowers keeping their shape and colour well for years – just hang a bunch up-side-down in a dark airy place and let them dry for a few weeks.
