Hazel Nuts

Pale green pixie caps
hanging bells
conceal
developing nuts
in hard case …
crack!
squirrel's teeth
or human tool –
deliver the
mature, delicious, nourishing
nut;

or

left to drop –
case softens, decomposes,
food feeds
inward growth –
embryonic root and shoot
elongate
become a little sapling
root anchoring it in the soil,
shoot rising for shade
and
new 
crop of nuts!
