smoulder

The smoulder stops our nose with stench.

Dry and wormeaten, a spark upon them became a smoulder, and a smoulder a blaze.

When grown as ornamentals it is important to inspect crops and physically remove rogue cultivars and other off-types, but whatever narcissus are grown for they should be inspected for signs of stem nematod lesions ('spickels'), disease 'primaries' (such as smoulder) and virus symptoms.
