Hello, does anyone know if you can save the seed from Melinus nerviglumis 'savannah' and sow it the following year?

I saved some from last year and it has sprouted but I cannot recall the seedlings looking so 'grassy'. If I remember correctly, they didn't look this way.

I want to plant them in a sort of prominant spot and don't wish to have any surprises.

Thanks for any help you can provide.

Eileen
