HARDY SHRUBS 
Roses: There are many species and varieties of hardy shrubby 
roses which are valuable in park planting. Perhaps the prairie 
rose (R. setigera) is the best of these. Many of the dwarf ramblers, 
multiflora roses, sweet briars, the Japanese Rosa rugosa and other 
varieties must be given careful consideration in any sort of planting. 
Pachysandra: <A very low growing herbaceous shrub especially 
valuable as a ground cover. 
Pearl Bush (Exochorda), a large upright rather coarse shrub with 
cheerful white flowers. 
Privet: There are several species of privet, all of them highly 
valuable. They will grow in shady spots where very few species 
will succeed. Their hardiness and their glossy green foliage make 
them excellent in foundation plantings and general shrub masses, 
while they are hardly surpassed anywhere for hedge plantings. 
Spice Bush (Calycanthus): Useful in general shrubbery masses. 
Spirea: This genus contains a number of species of the highest 
value in landscape work. The most popular are the Bridalwreath 
(S. Van Houttei) S. Thunbergii, S. callosa, S. prunifolia and the 
popular but ill-colored Anthony Waterer. 
Snowberry: A delicate, attractive shrub valuable for its white 
berries borne through the autumn and winter. To this genus 
Symphoricarpos belongs also the Coralberry, a good hardy shrub 
with pink fruit. 
Sumac: The best species in this important genus are the smooth 
sumac (Rhus glabra) the stag-horn sumac (R. typhina) and the aro- 
matic sumac (R. aromatica). 
Syringa, Mock Orange or Philadelphus, one of the old favorites: 
A large strong-growing rather coarse shrub with beautiful fragrant, 
white flowers. Some of the newer hybrid varieties are excellent. 
Viburnum: A number of species in this genus are valuable for 
garden planting. The best ones are V. acerifolium, V. cassinoides, 
V. dentatum, V. lantana, V. lentago, the high-bush cranberry (V. 
opulus) the snowball (V. opulus sterilis) the Japanese snowball 
(V. tomentosum plicanum). These are all hardy and easily grown.
