them objects of great beauty. Of the kinds with red berries 

 Mburnum Opulus, Viburmtm dilatatum, and Viburnum Wrightii 

 may be mentioned. Some of the others, such as Viburnum tomen 

 tosum, Viburnum Sieboldii, and Viburnum Lantana, have fruit 

 which is red at first, later changing to black, so that they too present 

 a period of bright color in the landscape. Viburnum tomentosum 

 has in its flower clusters a number of showy sterile flowers, giving 

 to the bush in bloom an unusual decorative effect, the clusters 

 appearing as small tables of white among the mass of green. Of 

 great decorative value are Viburnum Opulus sterile and Viburnum 

 tomentosum plenum, with balls of white made up of masses of sterile 

 flowers; the first of these is known as the guelder rose or snowball, 

 the other as the Japanese snowball. While most of the hardy 

 species are deciduous, one, Viburnum rhytidifolium, from central 

 and western China, is evergreen, and has proved hardy as far north 

 as Massachusetts. The only one of the hardy species with a striking 

 fragrance is Viburnum Carlesii, from Corea, which has also proved 

 hardy as far north as Massachusetts. A dwarf form is Viburnum 

 Opulus nanum, which usually forms a compact little shrub of 

 rounded outline. Some are greenhouse shrubs, such as Viburnum 

 Tinus, commonly known as laurustinus, and Viburnum odoratissi- 

 mum. One of the best for shady rocky situations is Viburnum 

 acerifolium, the dockmackie of our own eastern woodlands, where it 

 often forms large masses, its maple-like leaves giving it an appear- 

 ance quite imlike others of the genus. Propagation may be ef- 

 fected by seeds sown in the fall or stratified, or by greenwood cut- 

 tings under glass.
