HARDY HERBACEOUS PLANTS. 
be few more effective than A. saxatile , in May; and for June and 
July the pretty little A. montanum may be grown. 
4. Anemone japonicum will make a fine plant for the purpose, 
and will continue flowering through the entire period. 
5. Aquilegia. Several species of this genus appear desirable, 
particularly canadensis , glandulosa , Garnieriana , and Skinnerii. 
They will be good for June and July. 
6. Armeria cephalotes is a pretty plant, that has already made 
its appearance on the exhibition table, and therefore we know it 
to be good. 
7. Astragalus. This genus, though rather coarse, contains 
such free-flowering plants, that I think it ought not to be omitted. 
It is probable, too, when grown in pots, its usual vigour will be 
restricted. Species like tenuifolius , caryocarpus , microphyllos, 
and carolinianus promise to have the best appearance. 
8. Calendrinia speciosa and the pretty new umbellatus are just 
the kind of plants required ; but we must hope the sun will shine 
upon them, or their flowers do not open. 
9. Campanula. From this genus we may select an almost 
indefinite number. The blue and white varieties of pumila in 
pots are familiar to every one. Zoysii, carpatica , nobilis , mollis, 
alpina, and speciosa are all good; and, as back-row plants, I 
should think the double varieties of C. medium , or Canterbury 
Bells, would not be objected to. 
10. Delphinium. Here also we are presented with several 
very beautiful subjects. The new varieties Iveryana and Peck- 
hamensis will tell among a collection with great force, while 
some of the older kinds, such as grandijlora, Barlowii , chinensis , 
and others, will add lustre to the whole. 
11. Gaillardia aristata is a very showy, free-flowering plant; 
which would be in fine order by July. 
12. Globularia vulgaris, in May and June, and nana or nudi- 
caulis, in June and July, would be certain to be in admirable 
condition. 
13. Gnaphalium arenarium and sanguineum would form two 
good plants for our purpose. 
14. Iberis. Like the Alyssum, this genus is recommended 
alone for its beauty, in the estimation of some it may be regarded 
as too common ; but such plants as saxatilis , gibraltarica,
