They are used where heavy growth is needed; as among shrubbery or for a hedge. A single plant looks well on a lawn or at a corner of a house. The Rugosa roses grow from four to six feet tall.

Well, the reason for it all is this: Miss Gardener and Professor Weed are rose enthusiasts—‘rose crazy,’ we boys called them.” “Their love of roses was an excellent thing for you boys,” said his mother, “for I believe you know more on the subject than most grown-up people.” “Just listen!” exclaimed Mary Frances, “Billy, don’t you feel repaid for giving us the lesson? What comes next?” “Next comes—let me see,” replied Billy. “Oh, yes, it’s about planting and caring for roses, I remember.” “When will you give us that?” asked Eleanor. “Does it tell about ‘Tree Roses?’” asked Mary Frances eagerly before Billy could answer Eleanor. “I’ll tell you _now_,” he said, “about— TREE ROSES Tree Roses are Hybrid Perpetual or Hybrid Tea or other roses, budded or grafted high up on strong stock, or wild growth, and cut or pruned to the form of trees.

The two girls and his mother were sitting on the grass which made a thick carpet beneath its branches. “He used to say it over so often that the fellows nicknamed him ‘Rosy,’” Billy went on. “Oh!” exclaimed Mary Frances, “wasn’t that awful!” but she and Eleanor giggled, and even her mother smiled. “You didn’t call him that, though?” said Eleanor.
