From Baroness Schroeder, La Tulipe and Richardson's Rubra I have cut thirty roots in four years from one....Take Richardson's Rubra Superba, one of the most vigorous kinds. If divided every two years you will be surprised at the result; perhaps you will get from three to six from one. But you let them stay for six or seven years and they become as solid as a squash, and the best you can do is to cut out a bud with a piece of root.

Those of us who were at the Boston show will remember a lot of Richardson's Rubra Superba that came from Cincinnati and had been a long time on the way. They were badly wilted, and we shook our heads. But they were immediately plunged into water, when they revived and took the first prize over the home-grown
ones.

Richardson's Rubra Superba. Richardson, 1871. This, like his Grandiflora, brings up the rear of the flowering season. This is considered one of the best of all the crimsons. In cold storage it is kept a long time. At the Boston show in 1906 fifty blooms were brought from Ohio. They were a long time on the way and were somewhat wilted, but they revived and took the prize. When we can produce such flowers ourselves, we need not depend on Europe.
