    An historically significant daffodil described by the RHS at www.rhs.org.uk as 'Fl. 112 mm wide; perianth segments broadly ovate, blunt or truncate, fairly prominently mucronate, light greenish yellow 3C, spreading or a little inflexed, overlapping one-third or less; the inner segments more nearly acute, with margins wavy or recurved; corona funnel-shaped, more or less strongly ribbed, vivid yellow 12A, slightly tinged orange, with mouth straight, often deeply 6-lobed and overlapping, frilled, rim minutely and irregularly crenate. 2n=21'.
    aka - Incomparabilis Giganteus `James Dickson'
    Incomparabilis Giganteus `Sir Watkin'
    Giant Daffodil
    Mountain Daffodil
    and The Welsh Peerless.
    John Wister wrote that it “holds its place well among the best of fine daffodils, and proves once more that we cannot wholly cast aside old favorites.”
    Sometimes confused (especially in US) w/ Stella (2 W -Y)
