Chinese name yu zan
Plant 60 cm diameter x 45 cm high (24 x 18"). 
Leaf Petiole 24 cm (10") erect and spreading, unmarked glossy light green to yellowish green (often darker green with the addition of nitrogen fertilizers).
Leaf 16–25 cm x 15–21 cm wide (6.5–10 x 6–8"), erect and in line with petiole, becoming sub-pendulous, orbicular-cordate, nearly round, transition tight and contracted to slightly open, small cuspidate, interior surface “flat,” but undulate, wavy in the margin, not pruinose, surface dull, semi-glossy, below very glossy, light yellow green, tip acuminate, projecting.
8–9 (11) pairs of veins, sunken above, very projected, smooth below.
Inflorescense Scape 60–80 cm long (24–32"), straight, erect, yellow-green, smooth round. Fertile bracts, glossy green, ovate-lanceolate, grooved in the lower part, pointed; 2-bracted, bracteole within external bract, opposite to lower fertile bracts, flat, large to 8 cm, fleshy and rigid, green or greenish white; lower, sterile bracts often larger and foliaceous.
Compact raceme 25 cm (10"), 10–15 flowers.
NOTE: This is the only species in Hosta with flowers degeneratively duplicate, with one-flowered, sessile branches, appearing racemose, held erect in ±horizontal position on strong pedicels, fragrant, very large, to 12.5 cm (5") long and 7.5 cm (3") broad, waxy, shiny, lily-shaped, sharply recurving lobes, shiny white entirely, occasionally shades of white and pale cream, stamens not superior, parallel, joined to perianth tube; conversion of stamens to petaloid shapes frequent and occasionally without expression of anthers.
Anthers yellow.
Capsules very large, 7cm (2.7 in) long x 7–8 mm (0.3") wide, elongated, round, with a pointed tip.
Blooming Time August, night-flowering.
Fertility Fertile, but requires correct timing of pollination due to night-blooming

  • According to Mr.  W.G. Schmid, H. plantaginea 'Grandiflora' is the same plant.  This view isn't shared by everyone.
    H. plantaginea 'Stenantha' is a form with more narrow flowers on taller scapes.
