Detailed Solution
Long day plants (LDP) flower when the day length exceeds a critical value (i.e. when nights are short).
Spinach, wheat, radish, sugar beet and Hyoscyamus are long day plants.
Tobacco (Maryland Mammoth) and soybean (Glycine max) are short day plants, and Mirabilis jalapa is often given as a short day / day neutral example.
So spinach is a long day plant.
