the upper petals, with white and yellow centers. We used to grow 
Cymbalaria hepaticefolia (Linaria hepaticefolia), but it proved 
to be so ubiquituous that it was deemed advisable to eliminate it 
before it got beyond control. 
The Yellow Corydalis (C. lutea), seeds itself freely and finds 
harborage in chinks between the stones where it displays its 
handsome glaucous foliage and its yellow flowers from May to 
September. It delights in shade. 
A Willow-herb from New Zealand has seeded itself here and 
there throughout the rock garden. It is Epilobinm mnummulari- 
folium, a tiny creeeper that closely hugs the ground. Its small 
round leaves vary in color from light bronze-green to copper 
according to exposure and the time of year. Its little bits of 
flowers are of small consequence except as a means of repro- 
duction. Its seed-pods almost humorously resemble those of its 
cousin, the Great Willow Herb (F. angustifolium), thus disclosing 
its botanical affinities. 
June is the Bellflower month. Many of them just come and 
go, some are weedy and fit only for the wildflower garden, but 
some are permanent and beautiful. In the last group, we must 
include the Carpathian Bellflower (Campanula carpatica) and its 
many varieties. The variety turbinata of this species is reputed 
to be one of the parents of C. pulloides (C. pulla x C. carpatica var. 
turbinata), handsome with violet colored flowers. C. garganica 
and its varieties; C. rotundifolia var. Hostiu (Fig. 7), a glorified 
Harebell; C. eee C. rotundifolia, the Harebell, or 
Bluebells of Scotland, and C. versicolor, a moderately tall species 
along the lines of the Peachleaf Bellflower, are all good and easy 
to grow. The very rare Campanula speciosa (Fig. 23), from 
high limestone cliffs and screes in the Pyrenees does not, unfor-

tunately, belong in the 
us. The photograph of a group growing in our garden gives an 
inkling of what a glorious rock plant this species is. It forms a 
rosette of narrow, hairy leaves from which springs an upright 
spike of bloom—the individual flowers being like those of Canter- 
bury Bells. When, and if, obtainable it should be planted in 
well-drained, gritty, limestone soil.
