Botanical Description
The plants are medium, 18-35cm tall. The corms are 12-18mm in diameter.
The leaf is solitary, inserted well above ground, canaliculate, 4-10mm wide, exceeding the stem, usually trailing above. The stem is erect, flexed above the leaf insertion, simple, or few branched, the stem and branches flexed above the bracts. The stem bracts are 2-4cm long. The spathes are 5-8cm long, the outer about half the inner.
The flowers are pale yellow or salmon pink, with or without a deep yellow nectar guide edged in green. The tepals are forming a cup below, circa 12mm deep, enclosing the filaments and anthers, circa 10mm wide. The outer tepals are 30-35mm long. The claw is 12-15mm long, often papillate near the base. The limb is spreading horizontally, 10-12mm wide, obovate. The inner tepals are to 30mm long, circa 10mm wide. The filaments are united, the column cylindrical, 6-7mm long, lightly pubescent in the lower half. The anthers are 5-6mm long, contiguous in the lower half, slightly diverging above. The ovary is 14-19mm long. The style is branching shortly above the base of the anthers. The branches are 6mm long, diverging slightly and reaching the anther apex. The stigma is arched over the anther tips. The crests are short, circa 1mm long, erect-incurved.
The capsule is cylindrical, 30-40mm long with a short obtuse beak circa 1mm long.

Sowing instructions
AUTUMN After harvesting the seeds, keep dry for 8weeks at room temperature then keep dry in the fridge at 4°C until sowing. Sow the seeds at 4mm depth in the Bulb Substrate between 64-72°F. During germination keep the substrate moist and in daylight. The seeds germinate in 4-6 weeks.
The average seed weight is 1190,5 per gram (0,00084g).
The viability of the seeds, kept under good conditions, is 3 years.
