A FLOWER HOBBY 235 
Another very charming subject is the bellflower 
(Campanula). There is an endless number of bell- 
flowers, but not all are of interest unless one is col- 
lecting for numbers. A dozen or so perennial spe- 
cies, with the biennial Canterbury bell and the an- 
nual Campanula Loreyi, are distinctly worth while. 
Others are the phlox, with its species blooming over 
a period of six months; the pink (Dianthus), which 
has a long season also and some beautiful dwarf 
species that the garden seldom sees; the violet 
(Viola), which has some fine foreign species other 
than the ones that are the forebears of the pansy 
and tufted pansy and several native ones that de- 
serve more garden culture; the speedwell 
(Veronica), with profuse bloom over a long sea- 
son; the morning-glory (Ipomea), which has 
several fine species; the peony (Paconia), both tree 
and herbaceous; the columbine(Aquilegia), the 
poppy (Papaver), the stonecrop (Sedum), the 
saxifrage (Saxifraga) and the windflower (Anem- 
one). 
Among the bulbs and tubers there are more temp- 
tations to stroll down pleasant paths. The dahlia, 
in its well-defined classes, and the gladiolus, in the 
species and the choicest representatives of their 
hybrids, rank with the best flowers for hobbies be- 
cause of their quality possibilities. The tulip genus 
(Tulipa) and the daffodil (Narcissus), by either 
_species or classes; the crocus, the fritillary (Fritil- 
laria), the butterfly, globe and star tulips (Calo- 
chortus) and the dogtooth violet (Erythronium)
