I was sold 3 Fritillaria bulbs as F. davisii. However the flower looks more like F messanensis [looking at the archive photo by M.Sue Ittner] but and this is the problem; one plant has 8 flowers and the other 2 plants,4 flowers and 3 flowers per stem, respectively. Do they come multi headed? They are approx 7-10" tall growing in 10cm pots in multi purpose compost. I am new to the site, live on the edge of the chalky Yorkshire wolds East Yorkshire Great Britain. Thanks Eileen
