light and weather

Gladioli, being a plant typical of temperate climates as it is the case of the Mediterranean where they flourish in a spectacular way, they need to receive a constant sunlight. In fact, in the case of not receiving it, it is very possible that it will not produce any flower. However, if we are in a climate with high temperatures, we recommend placing the plant in a half shade so that it is not always exposed to sunlight, since this can not only damage the flowers but also the stems. Therefore, it will be better for the plant to remain covered during the hours of greatest solar intensity.

As we have commented above, most of the species of this genus are found in optimal conditions in a range of temperatures that goes from 10ºC to 24ºC. It is, therefore, plants of temperate climate. Although there are exceptions, such as the case of the Gladious nanuswhich can withstand temperatures typical of colder climates, although not extreme.
