SEASONAL EFFECTS Ler 
_ Spring, whereas later in the season, unless there is 
absolute isolation, only taller material will stand 
out by itself. As for habit of growth, foliage and 
stems may make one plant more desirable than 
another for a certain spot; thus Yucca filamentosa, 
for its form, might be a better July note somewhere 
than Platycodon grandiflorum, for its blue color. 
Perennials offer the lines of least resistance, 
because of their permanence; but some of the bien- 
nials, or plants best grown as such, are invaluable. 
These include self colored sweet-william and col- 
umbine, Myosotis dissitifora, Iceland poppy and 
hollyhock, as well as foxglove and Canterbury 
bell. Annuals are more useful as summer filllers 
than as summer accents, though at times not to be 
despised in the latter capacity. 
Miss Gertrude Jekyll’s theory of a seasonal gar- 
den is worth close study because she has put it to a 
practical test on her English place. ‘“‘I believe,” 
she says, ‘“‘that the only way in which it can be made 
successful is to devote certain borders to certain 
times of year: each border or garden region to be 
bright for from one to three months.” 
No doubt this is the best, if not the only, way 
when striving for the ideal is made a life work, as 
in Miss Jekyll’s case. But the plan is an admirable 
one for a place that is either very large or sufficient- 
ly diversified to permit the division of the garden 
into segregated sections. Miss Jekyll has an enor- 
mous summer border, a secluded spring garden 
and so on.
