Google <daffodil scilly> then select Narcissus, then www.scentednarcissi.co.uk , or just try the link direct, for information about the early bloom industry for the UK.
I have no idea how wide their market is, or what regulations imports may have imposed.
As to the white bits at the base of stems – daffodils, at least for the early market, are pulled (rather than snapped) to avoid splitting and having to trim too much off. I expect pulling doesn’t do much for the bulbs. Maybe they are completely replaced in summer ready for the next year.
I have seen blooms on sale here for 2 or 3 weeks.
In any case I hope that the Isles of Scilly daffodil industry is of interest.
