Blood lily flowers are comprised of large, 6-inch umbels, or softball-sized globes, borne on stalks about 12 to 18 inches tall. Each sphere has dozens of red florets with yellow stamens. This creates one of the showiest floral displays in the plant world. CAES News
Blood Lily 06/08/17 Norman Winter
The African blood lily is known botanically as Scadoxus multiflorus. It is in the Amaryllis family and is indeed native to South Africa. A lot of literature suggests it is perennial only for zones 9 to 11, but it is not hard to find long-term trials where it survives in zone 7b with great winter drainage.
Split bark, or vertical cracks along the lower tree stem of young trees, most commonly occurs on thin-barked trees like this plum tree. Large cracks can become long-term open wounds that are more susceptible to wood-boring insects, fungal diseases and wood decay. CAES News

A deer in its second year, a yearling, is caught by the lens of a wildlife camera. His small rack of antlers has grown over the past year. Antlers have the fastest growing tissue known to man. With the right nutrition, a buck can grow an excess of 200 inches of bone on his head in a matter of 120 days. CAES News
Deer Antlers 06/06/17 Michael Anthony Foster
Deer antlers are not horns, though the two words are often used synonymously. Horns are permanent, keratinized epithelial cells. The protein keratin is required to harden those cells. Antlers, on the other hand, are derived from endothelial cells that are grown and shed annually. These cells are grown from the tip of the sequential antler and are made of osteocytes, or bone cells, that calcify and harden.
