swaying branchlets, beset with minute pink or red, ethereal flowers. 
They are acclimated as far north as Massachusetts. In Ottawa only 
T.amurensis has proved half hardy. 
They will grow in almost any soil, 
and are especially adaptive to sea- 
coasts, thriving in the salt spray 
down to the very shore; they are 
rapid growers and free from any 
trouble. ‘To preserve their beauty, 
which lies in the branchlets and 
flowers, frequent, systematic prun- 
ing is essential, and this should 
be done at different times accord- 
ing to the species and its flowering 
habit, in order to ensure the throw- 
ing out of new branches and the 
flowers appearing on them. Other- 
wise, the black-barked trunk and 
the stout, straggling branches are 
not attractive. 
The species, very much alike, 
vary mainly in the time of flower- 
ing, suggesting the grouping of 
the three first mentioned for con- 
tinuous flower effect; they also 
group well with fine-foliaged coni- 
fers like cypress and cedars. 
T. parvifiora D. C. (Africana) 
(330), from South Europe and 
Africa, is the finest, with very 
early (May, June, before leafing), 
bright pink flowers, covering the

somewhat drooping branches. Should be pruned soon after flower- 
ing, since the flowers appear on branches formed in the previous 
year. 
I’. Germanica Linn. (331), with terminal red flower spikes, appear- 
ing in summer (July), z.¢., on wood of the present year, hence pruning 
should be done in spring; can be trained to any shape.
