Comments: Snow-In-Summer is useful in the rock garden or    
as a ground cover but its invasive tendencies must be kept  
under control.  The plant has silvery foliage.  A site      
with a sunny exposure and any well-drained soil is          
suitable.  The plant can be used on dry, sunny banks or     
other hot, dry areas.  The white flowers are borne in       
mid-summer.  Trim the plants back after they flower and     
expect some dieback during hot summer weather.

Propagation:  Propagation is by division, seed, or          
cuttings.  Division every 2 years may be needed to keep it  
under control.  Sow seed outdoors up to 2 months before     
frost.  Plants are spaced 4 to 6 inches apart.  Cuttings    
can be taken in late spring.

Cultivars:                                                  
   'Yo Yo' - Plants have woolly-gray foliage and white      
    foliage.
