Plant Hardiness Zone

Let us take a quick look at the map showing the US Plant Hardiness Zone published in 2012.

Plant Hardiness Zone Map for Virginia

Soil Order Of Virginia

Soil / Sub OrderLocationCharacteristics
Appalachian ridges and valleys/Ultisol and Inceptisolwest1. Have a udic soil moisture regime and thermic or mesic soil temperature regime
2. Are dominantly well-drained, strongly acid, and highly leached
3. Have a clay enriched subsoil
4. range from shallow on sandstone and shale ridges to very deep in valleys and on large limestone formations
Blue ridge mountains/Ultisols and InceptisolsEast to the Appalachian ridges and valleys1. soil moisture regime is udic
2. soil temperature regime typically is music, but it is frigid at elevations above 4,200 feet
Southern Piedmont/Ultisols, Inceptisols, and AlfisolsSouthern central1. have a thermic soil temperature regime, a udic soil moisture regime, and kaolinitic or mixed mineralogy
2. shallow to very deep, generally well-drained, and loamy or clayey
Northern Piedmont/Ultisols, Inceptisols, and AlfisolsNorthern central1. shallow to deep
2. gently sloping to steep soils formed in residuum from acidic or basic rocks
Upper and middle Coastal Plain/Ultisol and EntisolNortheast1. Deep to very deep
2. Nearly level to sloping soils formed in unconsolidated sediments of the Coastal plain and river terraces
3. Dominantly above 30 feet elevation
Lower Coastal Plain/Ultisol and EntisolSoutheast1. Deep, nearly level, and gently sloping soils formed in unconsolidated sediments of the Coastal Plain or inorganic materials
2. Dominantly less than 30 feet elevation
