time of the year, when most shrubs have passed out of 

 bloom. These Rhododendrons are particularly good this 

 year at Forest Hill Cemetery, Boston, and it needs but a 

 short visit to these grounds to be convinced of the impor- 

 tant place which they deserve in planting schemes of the 

 best sort. The specimens here are large, well developed, 

 well placed and sufficiently numerous to give one an idea 

 of the great attractiveness of the plant, and how well it 

 harmonizes with other native growths and with some kinds 

 of exotics. All these plants need for their best develop- 

 ment is first a deep soil, which should be as fine as possi- 

 ble, yellow loam apparently being quite as good as peat, 

 and then, when well established, they should have plenty 

 of water during the hot and dry July and August weather, 

 and this water should be given in large quantities, and not 

 in driblets. They do not require water frequently, but 

 unless they stand where their roots are in ground perma- 



LiGUSTRUM Ibota. — This fine Privet was introduced from 

 Japan in 1861 under the name of Ligustrum Amurense, but 

 it is only within the last ten years or so that it has been used 

 to any considerable extent in ornamental planting. Even 

 now it is not as frequently planted as it should be, but the 

 fine clumps in the Arnold Arboretum are so attractive that 

 they invite the attention of all who desire to increase the 

 diversity of their plantations. This plant is a shrub grow- 

 ing some fifteen feet high, of compact and symmetrical 

 habits, good foliage, and covered with numerous small 

 white flowers, borne in short terminal spikes, which open 

 late in June, after most shrubs have passed out of flower. 

 It succeeds in any good soil, and the form which is planted 

 in the Arboretum seems perfectly hardy in somewhat ex- 

 posed situations. The propagation is by seeds, by hard- 

 wood cuttings or by cuttings of the growing wood struck 

 under glass in June; it is apparently as easily handled as

nently moist a sufficient amount should be given to thor- 

 oughly soak the soil. A mulch of leaves or clippings from 

 the lawn is helpful, and some protection in winter is de- 

 sirable for the first few years. The propagation is by seeds, 

 but this should only be attempted by skilled gardeners. At 

 the Arnold Arboretum many hundred seedlings have been 

 grown during the last few years under glass and in frames, 

 and after the first year the growth is very satisfactory. If 

 small plants are obtainable, there is no great difficulty in 

 establishing wild specimens procured from the woods and 

 swamps. Any striking varieties which are found may be 

 increased by grafting, using the improved veneer graft 

 under glass during January or February. Stock is offered 

 in limited quantities by most nurserymen. A wide field is 

 offered for the hybridizer ; it is curious that such a thor- 

 oughly good plant should not have received more attention 

 in this direction. 



any of the better-known Privets. Although the type of this 

 plant which is grown at the Arboretum is perfectly hardy, 

 there are other forms, sometimes obtained from foreign 

 nurserymen, which do not succeed in our climate ; they are 

 apt, in trying seasons, to winter-kill— that is, the tops die 

 to the ground, but the roots survive and make a good 

 growth ; these annual growths, however, do not produce 

 any fiowers, and^so one of the great charms of the shrub is 

 lacking. 



OENOTHERA MissouRiENsis- — -This is one of the best of the 

 Evening Primroses, and is a most desirable plant for the 

 herbaceous border. It is low and spreading, the leaves 

 are long and narrow, the fiowers are yellow, measuring 

 three inches or more in diameter and are produced in 

 abundance from June to August. The plant is hardy and 

 requires no protection in ordinary situations. Its cultural 

 requirements are simple, a fairly well-drained soil and
