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 (Ipomcea), which has 

 several fine species; the peony (Paeonia), 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)
