We see it stated that the Gardeners' Monthly is opposed to the idea that asparagus can be crossed. Nothing is further from the fact. The Gardeners' Monthly was really the first to show, even many years ago, that the asparagus had separate sexes, and that it really could not seed at all unless crossed; that is to say. that one plant must have the pollen from another plant in order to produce seed. The position of the Gardeners' Monthly simply is that there cannot be any special variety, such as some named plants have been sent out. But there is no reason why there may not be an improved race. If, for instance, a female plant which is a strong grower and delicious eating, is fertilized by a poor wiry plant, the progeny may be expected to be inferior. If fertilized by one as good itself, the progeny would be superior. There can be no question about which seed would produce the best results. The plants would not be uniform, but there would be a general superiority. There can be no special variety of asparagus, but there can and there ought to be great care in the selection and isolation of plants intended for seed, if one wishes to keep at the top of the heap with first-class asparagus.
