I know that you can buy zinnia seeds just about anywhere, but I thought you might like to see where we get them.

 

At the base of each zinnia flower petal is the seed.  When the flowers are mature, you can pluck out the seeds.  Just save them until spring and plant them.  I've had pretty good luck doing it this way.

 

And sometimes I just drop those seeds on the ground and they come up in the spring.  Not quite as sure a thing, but sometimes it works.  We call it lazy gardening...

 

HAPPY GARDENING!!!
