Saving Zinnia Seeds

Happy first day of spring! I'm waiting until April to start seeds indoors, even though the weather is fabulous today and tomorrow, in the sixties and maybe 70 F tomorrow. I know I wrote earlier that I gave up on saving the bright pink zinnia seeds, but the saga continues. I couldn't help myself. The flowers are delightful--bright, cheery, long-lasting blooms. 

This is the seed head I brought inside. Are the seeds mature enough? I won't know until I plant them. 

Spring is the time of hope.
