Yes. You can eat a dandelion.
Dandelions are edible and can be picked and eaten and I find the yellow dandelion flowers to be very sweet tasting.
I used to eat the dandelions as a kid and they were very good.
Just make sure you don't eat any dandelions that might have had pesticides or weed killer sprayed on them.
I didn't know the dandelions were edible until one day when I was 3 years old and at my Grandpas and Grandmas house and my Grandpa was telling me that I could eat it.
I was playing with a dandelion in his yard and my Grandpa got me to try to eat one after he ate one.
They are healthy for you too and all dandelions are edible but as the dandelion grows bigger and gets older it becomes more bitter tasting.
Dandelions are best eaten when young and yellow.
