Guide to growing Immortelle - Xeranthemum
The Xeranthemum genus of plants consists of hardy annuals that range in height from 60 to 90cm.
They have a silvery foliage and bloom from the middle to end of summer when they carry leaves reminiscent of daisies; these may be pink or purple.
A common variety of Xeranthemum grown in the garden is Immortelle.
How to grow Immortelle
It is best to start off Immortelle indoors. Sow the Immortelle seeds in peat pots about three weeks before the last frost of spring. It should take about two weeks for Immortelle and other Xeranthemum species to germinate at a temperature of 20 degrees Celsius. Once growing transplant the Immortelle seedling outdoors following the last frost at a spacing of 20 to 40cm. Ideally Immortelle should be grown in a sunny part of the garden; the soil type is not too important.
Caring for Immortelle
It is easy to grow an look after Immortelle as they can tolerate dry soils so can pretty much look after themselves; however a splash of water every now and again will not go amiss.
