A Bed of King Humbert Cannas
Most gardeners experience difficulty in growing cannas from the seed. Mr. Burbank's method is to sterilize the seed and put it in sterilized gravel for germination. He does not find it necessary to file or otherwise to treat the individual seeds, as is sometimes done by florists, owing to the hard shell. The picture shows the thrifty character of a bed of King Humbert seedlings.
