How To Know If Edible Blue Flowers Are Safe?
Most previous research has shown that many blue flowers are safe to be ingested, for example, several blue flowers we have stated before. But what about any other plants that also produce blue blooms? To check this out, we can adapt the edibility test.
First, identify the taste. Even though bitter taste can’t be an indicator of whether the blue flowers are edible or not, generally, bitter taste in plants is linked to toxicity. The noxious level can be either low, medium, or severely high.
Second, do the skin test. Pick one or two of the blue flower’s petals and see if there are any physical reactions such as skin rash, burning sensation, or itchiness.
Third, eat a small portion of the blue flower’s blooms and wait for at least 8 hours to see if there’s any discomfort. If nothing happens, then it’s safe to say that the blue flowers are edible. But please note that this is the least recommended way to check if a blue flower is edible or not.
