In July 1901, as the number of Lily species available to British gardeners grew to around 50, a Lily conference was held at Chiswick to discuss the botany of the genus, the new arrivals, their cultivation and healthy maintenance.
In its editorial on the event, The Gardeners’ Chronicle noted of the known species, "all are interesting, and most of them beautiful". It added: "There are but few which the fastidious cultivator would care to eliminate".

Alongside its report, the chronicle published a selection of drawings including one of Lilium x Parkmanni (see below) which was feared to be no longer in existence although regarded as "one of the very finest hybrids".

While hybrids known in Europe at that time were few in number, the chronicle reported that "the great Californian hybridizer" Luther Burbank had announced in his latest catalogue that he had ten thousand hybrid Lilies produced on his grounds.
