A description according to Daffodils, narcissus, and how to grow them as a hardy plants for cut… 1907 by Arthur Martin Kirby, when identified as ‘Double Van Sion’, “This famous double yellow daffodil of old American gardens is also very popular in Europe under the name of ‘Wilmer’s Double Golden Daffodil’ and among the more botanical as N. telamonius plenus, it being the doubled form of a single yellow trumpet called ‘Telamonius’ in England and ‘Van Sion’ in Holland. Like its parents Double Van Sion varies in size, form, and other characteristics accordingly as influenced by environment. Another vagary of the ‘Double Van Sion’ is its tendency to produce flowers tinged with green and sometimes almost all green.

A quote from the January 1966 edition of The American Horticultural Society Magazine: In Section 18 “Daffodils in the Netherlands” at page 175, written by Gustave Springer, writes about what is now known as the synonym ‘Van Sion’: The most famous is of course the double Van Sion (Telamonius Plenus). This amazingly durable variety dates back to 1620 and was first introduced by Vincent Sion. Somehow it was listed as V. Sion and it was inevitable that everyone soon forgot what the “V.” signified. As could be expected V. Sion became Van Sion and for some Von Sion.

Origin of Name

According to E.A. Bowles’ writings in A Handbook of Narcissus, in 1934, “Its first appearance in England is that chronicled by Parkinson, who tells in the Paradisus that Vincent Sion, a Fleming, living in London, cherished it in his garden for many years before it flowered in the year 1620. He thought that John de Frauqueville might have given him the bulb, but that worthy disclaimed the honor, never having seen the like before. Before his death Van Sion gave bulbs to George Wilmer of Stratford Bowe, and also to Parkinson, who seems somewhat aggrieved that Wilmer ‘would need appropriate it to himself, as if he were the first founder thereof, and call it by his own name Wilmer’s Double Daffodil, which since hath so continued.”

“It was not the only name it was to bear, for Hayworth invented an Ajax Telamon (named after the father of Ajax), but afterwards changed the name to Telamonius. He provided a very poor description for it, and it is hopeless to attempt to recognize any single-flowered form now grown, as his ‘long-flowered’ Ajax. He regarded it as the single form of two doubles, for the first of which, Grandiplenus, the great double, he cites Parkinson’s Fig. 7 on p. 101, called there Master Wilmer’s Great Double Daffodil. Therefore the name, Telamonius Plenus, has been widely used. As there is only Hayworth’s word for connecting it with the intangible Telamonius, it is better to call it by the garden name Van Sion, and to give honor to whom, according to Parkinson, honor is due.”
