PERENNIALS FOR SPRING AND SUMMER TRADE 217 



to the potting shed. In the case of Shasta Daisies, Achillea, Physos- 

 tegia and many others of which good sized plants can be had, these 

 can be divided into small pieces, just large enough to be potted up 

 in 3j/2-in. pots. After this they can again be brought in to a cold- 

 frame, given a thorough watering and protected with sashes to keep 

 heavy frost out. By the middle of March or so, according to weather 

 conditions, remove the sashes altogether, for you don't want to 

 encourage growth but rather to retard it. 



Don't draw on these plants, except for shipping, until it gets 

 too late to lift field plants When that time draws near is the time 

 to push the potted stock. Let the people know about it, advertise 

 it, make people think of it. Gall attention to the advantage derived 

 from planting such stock and you will surely find sale for it. 



TWENTY-FIVE BIENNIAL AND PERENNIAL FLOWERING PLANTS 

 ARRANGED ACCORDING TO THEIR IMPORTANCE TD THE FLORIST 



From the florist's point of view, all such plants as come under 

 the head of biennials, perennials, and herbaceous or hardy flowering 

 sorts, have to be judged first by their individual value as cut flowers, 

 for this is of greatest importance to most of us. A variety which 

 will produce desirable cut flowers over the longest period should 

 come first, especially if it furnishes flowers which adapt them- 

 selves to many purposes. Next in importance we have to consider 

 its hardiness, then its ease of culture and next, for the retail grower, 

 the ability to dispose of the plants themselves not only at retail to 

 his patrons during Spring and Fall, but also, in the case of any 

 surplus, at wholesale to the trade for growing on. 



Every retail grower with space outdoors in connection with 

 his greenhouses should have a stock of the following sorts always 

 on hand. Most of them are easily grown on, either from seed 

 or divisions of the field plants or clumps, and with just a little 

 attention they will bring as good, if not better, returns than almost 

 anything handled in or outdoors. The botanical or common name, 

 according to which the plant is best known by, is used in each case. 



ACHILLEA PTARMICA FLORE PLENO, "The Pearl." You cannot 

 ask for anything more useful for sprays or in a basket arrangement 

 of flowers than this Achillea. Small divisions planted one foot 

 apart each way in September, will flower for three months the 

 following Summer. (See page 243.) 



ANEMONE JAPONICA. If these Anemones were just a little 

 more hardy, they would become as popular as any perennial grown, 

 for their beautiful flowers are at their best when we need flowers 

 outdoors the most. (See page 253.)
