This is a canna lily seed, just beginning to sprout.
In order to get these guys to grow, I had to scrape them with pruning shears to
allow some moisture in past the hard shell.  Then I soaked them in water until these little
sprouts started to pop out, and I promptly put them in soil and into the propagator.

These are several of the ones that have sprouted so far.  Still about 15-20 seeds left.

On the left are canna lily sprouts.  in the middle are hosta sprouts.
Circled in red is the first of 3 Strelitzia "Birds of Paradise" sprouts (assuming the other two will sprout eventually!)
Circled in yellow are the first two (of hopefully dozens) oriental lilies to sprout

These lilies don't seem to be doing much....

This is a tray full of hosta sprouts.

This is a tray of daylily sprouts

Also currently sprouting in other trays:  lots more oriental lilies, lots of hibiscus, more daylilies and hostas, and a tray full of cannas that are starting to sprout.
