A great example of how some stoloniferous bulbs can seek their proper depth in the soil. The original little seedling bulb from last season is at the top. This season it sent out two stolons terminating in bulbs. "Up" is up in the pic, "down" is down in the pic. The structure looks like the photo was taken at an angle because the lower section is larger, but no. The plant lays flat on the soil with the camera directly above. These types of bulbs must also be handled gently. Stolons and bulbs scales are brittle.
