Calendula seeds are the most unique-looking seed I have planted yet.

It looks more like a dried up part of the flower that has curled back upon itself, revealing a spine with a double ridge. 

Experiment Questions:

1. How many seeds per hole?

I am starting some today and don't know whether i should try to fit two to a hole, or only one. I will try it both ways and see which way works best. One of the seeds in the single-seed trials was broken in half. we'll see if it still germinates, since I am unsure as to what part of the seed has the embryo.

Results:

1 seed per hole: 100% germination with these 2 year-old seeds, from Seeds of Change. Even the broken seed germinated

2 seeds per hole: getting two of these large seeds into the same hole was a challenge, but both germinated.

2. Where does the plant germinate from?

From the dots on the ridge? or from the base of the curl? I managed to break one of the seeds, so we'll see if that one germinates. It's in a hole on its own
