Signs of Cold Stress in Paperwhite narcissus
Symptoms
Paperwhite narcissus tolerates cool temperatures moderately well and flourishes best when temperatures exceed 50℉. In winter, maintain temperatures above 45℉. If the temperature drops below 32℉, foliage may begin to sag. Mild cases can recover, but severe cases lead to wilting and eventual leaf drop.

Remove any parts damaged by frost. Before further cold exposure, cover the plant with materials like non-woven fabric or cloth, and build a windbreak to shield it from cold gusts.
