And indeed for humans. Early leaves make an excellent salad or cooked like  
spinach. Not too many as they are a diuretic. The flowers make an  
excellent wine and I collected hundreds today for that very purpose.

Dear  All,                     May 25, 2015
I noticed some years  ago that Dandelion scapes, at anthesis, are shorter 
in fall and  tentatively attributed this to an effect of cold.
This year I  realized that it is not an exclusive response to cooler  
temperatures.
Scape length of plants along a path exposed  to foot traffic when the 
soil was still wet and subject to compaction is  very short (2-3 cm) 
suggesting a reaction to poor aeration. Scape length  in adjacent areas 
with 
no or moderate foot traffic is normal (19-22 cm)  and very long (35-40 cm) 
on 
a pile of loose earth with scant competition  and no traffic. But in a 
small 
area of light soil (good aeration and very  poor water and nutrient holding 
capacity) length is somewhat short (8-10  cm).
So scape length may be a reflection of growth condition  adequacy. And 
Dandelions are thus desirable in lawns as indicaters of  marginal 
conditions 
such as compaction or excessively light soil (chinch  bug prone) in 
addition 
to serving as food plants for many insects.
