as hardy as Oalis, yet are very attractive when in bloom from August 

 until frost-time. The flowers are borne on long, graceful stems, divided 

 like a plume, and are either light creamy or yellowish-white in color. 

 The foliage is very finely cut and \aries from light gray to dark green. 



Species. Hawthorn-scented Mugwort. A ladiflora is one of 

 the newest varieties which grows 5 feet high. Its fragrant flowers are 

 produced in late Sunamer and combines well with the Golden Glow, 

 Buddleia, Hardy Asters, Boltonia, Helianthus and many other of the 

 taller Fall blooming perennials. It shows a tendency to disappear like 

 the Auratum Lily does. 



Southernwood, Old Man (A. Ahrotanum) is one of the old-fashioned 

 border plants. It has yellowish-white flowers and is usually grown for 

 its handsome dark green, pleasant scented leaves. 



Old Woman {A. Sielleriana) is of creeping habit with silvery white 

 foliage and is one of the showiest of this type of border plants. It 

 grows rapidly and soon covers a large space. 



A. Purshiana grows about 1/^ feet high and has white foliage. 



The Summer Fir or Annual Pine (A. saccrorum) is an annual re- 

 cently introduced from China which because of its fine foliage and 

 rapid growth has become popular for foliage masses. 



Uses. Old Woman is much used for carpeting beds or borders. 

 It is good also for the rock garden. The taller plants are used to fill 

 in the shrubbery or as backgrounds or hedges for the lower growing 

 flowers. The fohage and flowers are sweetly scented and adapt them- 

 selves well to pot culture and as such are as decorative as many of 

 the Acacias which are prized so much. The blooms also make attrac- 

 tive cut flowers and last weU. 



Culture. Artemisias like soil which is moist, and it must be 

 rather rich in order to produce good blooms. Free watering and soap- 

 suds have been found to agree with them. 



Propagation. They may be grown from seeds, but are usually 

 propagated by division or by cuttings.
