Saved lots of seeds from the whirligigs and button box this last summer. Decided to grow some under shop lights as an experiment, in the furnace room, just one plant of each type.
5 weeks later I have blooms ! The whirligig is a very fiery red and some magenta, which a colour different than what I had saved it from. The button box looks identical to its parent which was a vigurous well branched orange zinnia.. pretty cool ! Now I know to start mine first of May with the plan to plant out June 10th or so
