How to stop open pollination of sunflowers
| | |
Posted by spiderpig NM (My Page) on Thu, Sep 24, 09 at 18:39
| My favorite sunflower is Russian Mammoth (Diane's strain) and the only place I can find the seeds is P and P Seeds, (5 seeds $5.00). So I was happy to grow my own seeds for this years planting. None of the flowers looked like the parent plant. How can I reproduce flowers like the parent? How do seed companies do it? I was so disappointed to have a garden without my favorite plant. |

| Sunflowers generally have a self-incompatability trait which results in most seeds being hybrid. If you want to ensure seeds will produce plants like the parent, you could try preventing cross-pollenation by covering the developing flower head with a light fabric bag. I haven't done this, so I can't give specific directions. |
