The blossoms on our yellow calla lily are drooping over even though we watered them. What would cause this condition, and is it normal or do we need to do something differently? The plant was obtained from Home Depot. It was pre-potted with a grouping and it is is the sun daily. Plant leaves appear very healthy, but blossoms are "leaning over." Tthe stem of the blossom is actually curved, but seems strong - almost as if it is too heavy to stand up.
