Here is the rosemary seedling that I started almost 7 weeks ago - out of 30 or so seeds, this was the only one that germinated. I have since started a few more, but it has been very challenging. Out of a $3 pack of about 100 seeds, I have maybe 10 sprouts which I have been coddling day after day - heat mat, sometimes dark, sometimes under the fluorescent light - anything to get them to germinate and grow!!
And here is the rosemary plant that I just bought at a local grocery store for $2.
Need I say more?
