Retinal detachment is a very serious eye condition that happens when the retina separates from the tissue around it. Since the retina can't work properly under these conditions, you could permanently lose vision if the detached retina isn't repaired promptly.
Plant Hardiness. Cannas are reliably hardy as far north as Zone 7, which includes New Yorkâs Long Island, Virginia, the Delmarva peninsula, southern Tennessee, mid-state Missouri, southern Oklahoma and parts of the Texas panhandle, as well as patchy areas of the Sierra Nevadas and West Coast mountain ranges.
Long Island temperatures vary from west to east, with the western part (Nassau County) of the island warmer on most occasions than the east (Suffolk County). This is due to two factors: the western part is closer to the mainland, and it is more densely developed, causing the  urban heat island  effect.verage yearly snowfall totals range from approximately 20 to 35 inches (50â89 cm), with the north shore and western parts averaging more than the south shore and the east end. In any given winter, however, some parts of the island could see up to 75 inches (190 cm) or more.
