Fritillaria, Crown Imperial Fritillary 'Rubra Maxima'

A magnificent plant if you have large enough area to grow them and can stand the smell that emanates from these plants. For several year...Read Mores we grew them in a deep tub, where they increased year by year. The huge bulbs have a very pungent smell...cross between fox and mice is the only way of describing it. The foliage also smells the same.
We planted several bulbs in the flower borders and lost most to slug infestation. The slugs devoured most of the inner bulb leaving just the outer casing. These bulbs do grow well in large tubs and if you have a slug problem I would advise growing that way. The plants grow very tall and will need staking to prevent wind damage.
I understand that they are pollinated by birds and not insects?
