In the selection of bulbs for garden plantings we have practically theentire field from which to draw for material adapted to the refined lawnand garden planting. The degree of refinement depends largely uponour knowledge of the proper combinations of bulbs which will giveinteresting flower effects, flowers that appear at the same and at suc-cessive dates, and flowers of the same height. In making plantings ofbulbs for lawn and garden effects careful attention should be givento the other groups showing narcissi for different locations, and theinteresting tulip combinations. One of the most interesting groups of bulbs is the group valuable fornaturalization in woodland and wild garden areas. These bulbs mustbe of the kind that will continue to multiply without further care thanis ordinarily given to such areas on the average estate. All of the bulbsin this list should, after being properly planted, grow in succeedingyears into clumps through the increase of the small bulblets, and themature plants should be almost as vigorous as during the first year ortwo after the bulbs were planted. In other words, they should notshow a tendency to run out. Occasionally, unless conditions are ideal,such plants as the trillium and some of the lilies will continue togrow but will not multiply. This is a freak of plant life which thosewho have given considerable thought to experimenting in the natural-ization of plants cannot fully explain. Many of the bulbs in thisgroup such as the yellow lily leek, lily-of-the-valley, adder's tongue,and trillium, desire a great amount of shade. The other bulbs such aslilies, narcissi, squills, and tulips require more sunlight. |
