This charming floral gem was first distributed to plant cultivators four years ago by the late John Sadler, of the Royal Botanic Garden, Edinburgh. It was raised from seed sent by Mr. Lister - a former employe of the above-named establishment - from the Himalayas. In Europe it has already become a great favorite, not only with botanical enthusiasts but also with florists. In most respects its appearance is totally distinct from, and with the exception of P. acaulis and varieties, much more floriferous than any other species in cultivation.
My experience with it is, that, although it is perennial, it will repay the trouble to treat it as an annual or biennial grown for winter flowering. It seeds freely and if sown by the beginning of August we have the plants in flower before Christmas. The flowers are bright yellow, arranged in whorls, there being sometimes as many as eight successive whorls on a single stalk. As soon as the seedlings permit of being handled, they should be potted singly into thumb pots and shifted on as they require it, using sandy loam until the last shift which should be into six-inch pots, when a goodly portion of thoroughly decomposed cow manure may be added, potting very firmly.
