I can attest that N. miniatus (which I am told is the correct name of 
most cultivated "N. serotinus") and N. serotinus itself do not need 
exposure to sea air or salt spray to flower, as I have been growing 
flowering specimens in my bulb frames for years about 175 km from the 
ocean, and I have also seen these species flowering in nature so far 
inland that they would not experience such influence, unless perhaps 
salt spray were picked up in a storm and fell with rain.

There are other plants that are, in nature, found on beaches just 
above the high tide line, but that can be grown elsewhere without 
special chemistry, e.g. Alstroemeria pelegrina. I suspect that they 
are salt-tolerant rather than salt-requiring. However, it is known 
that plants that grow in substrates that are toxic to many plants 
(such as ultramafic/serpentine) may suffer more from pathogens when 
growing elsewhere. Perhaps the sea influence restricts some kind of 
disease organism that would otherwise attack the plants?
