My wife Cheryl loves spring flowers so, unbeknownst to her, I stuck some miniature daffodils into our front yard. This is the result.
The flowers are only 1″ across. If you want to try this in the fall just stick a shovel 6-8″ deep and push forward. With the shovel still in the ground stuff the small bulbs to the bottom, pull out the shovel and tamp the lawn back in place. No one will be the wiser.
