Appearance and bloom

This gladiolus produces elegant yellow to brownish-yellow flowers on slender spikes. The blooms are graceful and refined, typically 4-6 flowers per spike. Most characteristic is that flowers open in the afternoon and evening, releasing a strong, sweet fragrance. This is highly unusual for gladiolus species.

Ideal location
