I planted Jerusalem artichokes around February.  Today, I noticed that they are blooming.

I’ll add a picture later when my camera has charged.

Addendum:

This is what they look like blooming.  at first look, very similar to the swamp sunflowers by the shed and on the side of the house, but with different leaves and very different roots.  Also, slightly different bloom times.

This is what the sunchokes look like up close.

And this is the swamp sunflowers.  They are just starting to form buds.

Both plants are great to feed pollinators at the end of Summer and in the Fall.  Both freeze to the ground in Winter.  Both are very tall and flower heavily with yellow blossoms.

Only one will feed you.
