Bloodmeal or not is up to you. You can lay chicken wire on top of the planting area too. Hold down the edge with bricks. Remove everything after the ground has frozen.

Yes - convex down, concave up. What is the bonemeal for? C hederifolium doesn't need rich soil. It is one of the few things which will thrive in dry shade under trees. This is what you have to look forward to.

Are those flowers from one corm?

The directions claim that I should dig 6" deep, add humus and to plant them 2" from the surface. This suggested adding bone meal also.

Dry soil in pine tree shade is what I have plenty of. (-:

I don't know how many corms there are in there. But probably two for the pink and one for the white. The corms grow several inches across. They spread by seeding themselves. The brown marble sized sphere on the right of the clump is a seed pod. A little to the left there is a spiral seed pod stem. The start off straight and then literally screw themselves down towards the ground.
