Panicle hydrangea (H. paniculata) is the most cold hardy member of the genus. It can be reliably grown in USDA cold-hardiness zones 4 to 7. Native to Asia, it grows 10 to 15 feet tall. Large creamy-white flowers, which are borne in 6- to 18-inch long panicles, are produced in mid-summer (see image at left).
Life cycle. Trichinella spiralis can live the majority of its adult life in the intestines of humans. To begin its life cycle, Trichinella spiralis adults will invade the intestinal wall of a pig, and produce larvae that invade the pig's muscles. The larval forms are encapsulated as a small cystic structure within a muscle cell of the infected host.
Trichinella s. survives well in their environment because the female worm can produce 10,000 eggs per day. More the 2.2 million people in the United States alone are infected by these parasites. The niche of the whipworm is living in the intestinal lining of hostâs large intestines. The whipworm population is not endangered and this parasitic worm can live for several years if not treated. The female Trichinella spiralis can lay up to 10,000 eggs a day.
