A Thrifty Yearling Cactus
Here Is a year-old plant of one of Mr. Burbank's improved varieties of spineless cactus. So thrifty is this youngster that it will need to be considerably thinned by the removal of numerous slabs, if it is to attain symmetrical growth. But of course each discarded slab may serve as the basal slab of a new plant just like the parent.
