24 MONTANA EXPERIMENT STATION 



which often injured the buds. In years when the foliage is not in- 

 jured before the wood matures, the trees go through the winter with- 

 out harm. At lower altitudes in the state it is perfectly hardy and 

 is one of the very good ornamental trees. It grows to a large size, 

 has a spreading head, and affords excellent shade. 



LABURNUM 



Scotch Laburnum: (Laburnum alpinuwi) This plant be- 

 longs to the order Leguminosae and grows to a height of 25 to 30 

 feet. The flowers are pea-like in form and the seeds are produced 

 in pods. At this station it is not entirely hardy, the current year's 

 growth killing back every winter one-half or more. 



PRIVET 



The genus to which this plant belongs includes several orna- 

 mental shrubs or small trees, with deciduous or evergreen leaves. 

 They are valuable for shrubberies and group planting and some of 

 the species are used in hedges. They are propagated by seeds, 

 which are either sown in the fall or stratified and sown the following 

 spring. They are also increased by cuttings of mature wood. 



California Privet: (Ligustrum ovalifolium) In 1898 plants 

 of this species were set out on the college campus. They are 

 half evergreen plants and are not well adapted to this altitude, the 

 terminal growths frequently killing back one-half or more. At 

 lower altitudes in the state, where there is a longer growing season, 

 they will no doubt prove hardy and be adapted for general culture. 

 (Ligustrum Amwrense) Plants of this species were set out 

 in the experimental nursery in 1907. They killed back each winter 

 and are not hardy enough for general planting. 



(Ligustrum ovali/olium var. aureo-mar^inatwrri) This is 

 hardy here if given slight winter protection. The leaves are edged 

 with yellow and are evergreen. 



(Ligustrwm Ibota) This was planted in the experimental 

 nursery in 1905, but died the first winter. 



THE HONEYSUCKLES 



These are ornamental deciduous shrubs of upright or climbing 

 habit. The leaves are opposite and entire; the flowers are small, 

 pea-like in form and have a variety of colors, including white, yel-
