Although some would describe Limona as a "flawed yellow", it has many strengths.  The plant is strong growing and the flowers are large and fragrant.  It does have pink markings, and (at least in the bulb I grew last year) seemed to have irregular horns which may indicate Yellow Pioneer heritage.

Large bulbs are 30+ cm and should produce 2-3 flowering stems.
