If you define orbit to mean the time it takes the Moon to come back to its perigee, that is an anomalistic month, which is 27.55455 days. If you define orbit to mean the time it takes the Moon to return to its ecliptical ascending node, that is a draconic month, which is 27.21222 days.
Almond trees (Prunus dulcis) grow in zones 7 to 9, producing edible fruit and showy, fragrant blooms in hues of white and pink. To achieve the best fruit production, two or more almond trees are required. Almond trees reach heights of only 10 to 15 feet and grow well in compact gardens.
Zone 5 is still risky for the tree. If you haven't heard by now, Ohio is in a whole new zone -- plant-hardiness zone, that is. Last month, the U.S. Department of Agriculture released its Plant Hardiness Zone Map, the first update since 1990, that shifts most of Ohio from Zone 5 to Zone 6. The new map reflects sustained warming in the Buckeye State and much of the country. This didn't come as big news to folks in the botanical industry, especially since the Arbor Day Foundation issued its hardiness zone map reflecting a climate shift about six years ago.
