If necessary we can extract the bulbs from the ground, during the vegetative rest; after letting them dry we should place them in a cool, dry and dark place. During the most indicated season we can plant them again. We suggest to position the the Imperial fritillary in a sunny spot at least a few hours a day.We advise cultivating the the Imperial fritillary outdoors, since it doesn't fear cold temperatures.
Fertilize Imperial fritillary
Bulbous plants use nutritious substances stored from the previous year for their flowering ; this is why usually the soil should be enriched, during planting, with a slow release or organic fertilizer. Later we must fertilize with a specific fertilizer for bulbous plants, every 15-20 days, starting from the moment in which the first flowers are withering.

The Imperial fritillary is large in size and 1,5 m in height; in the spring it assumes a orangered colouring. These plants aren't evergreens, which means they lose their leaves some months during the year.
Water Imperial fritillary
Water sporadically, with 1-2 glasses of water , leaving the soil dry for a few days before watering again; when watering we suggest avoiding excesses, but to wet the substratum well. Let's act every 1-2 weeks . These plants don't need too much water; staying in a soil which is too damp, can easily cause the development of rotten in the bulbs.
