The AHA's General Guide adds: 'Stable' should not be used as a condition. Furthermore, this term should not be used in combination with other conditions, which by definition often indicate a patient is unstable. (As one hospital spokesman put it, You can be dead and be stable.)
Growing season. The growing season is the part of the year during which local weather conditions (i.e. rainfall and temperature) permit normal plant growth. While each plant or crop has a specific growing season that depends on its genetic adaptation, growing seasons can generally be grouped into macro-environmental classes.
The Plants. Many of the gardenâs most colorful flowers are annuals that explode with color on fast-growing plants. Marigolds (Tagetes erecta), zinnias (Zinnia spp.) and China asters (Callistephus chinensis) all grow from USDA zone 2 to zone 11, but only for one season.nother perennial, tulip (Tulipa spp.), hardy from USDA zone 3 to 8, must be grown as an annual in higher zones because winters do not provide sufficient chilling to produce flowers.
