M. asks : "Is it possible to have this plant so as to perfect its beautiful seed vessels without planting two together? A gardener tells me it is a dioecious plant, and one planted by itself will not seed".

[It is rather polygamous than dioecious, that is-to say there are some plants wholly barren when alone, but there are Other plants which have perfect flowers, and by themselves produce seeds. Cultivators should select these perfect flowered plants for propagation. - Ed. G. M].
