I don't think petite is a height so much as a body shape. I have seen tall women shopping in the petite section because they have a short waist or shorter arms or wanted a skirt that fits them better than the regular ones, and I have seen smaller women shopping in the junior/misses/womens section for similar reasons.
Sweet clover needs a high pH, 6.0 or higher, for proper nodulation to occur, and it has a higher calcium requirement as well. Sweet clover is able to obtain phosphorus from relatively unavailable soil phosphates and will grow on soils where alfalfa, red clover or ladino will fail.
White clover (Trifolium repens L.) is a short-lived perennial that can reseed itself under favorable conditions. It grows rapidly and spreads via stolons. White clover has a shallow root system, which makes it intolerant of droughty soils.It grows best during cool, moist weather on well-drained, fertile soils with a pH between 6 and 7 (Table 1). Pure stands of white clover are not usually planted because of their low growth habit and associated low yield.hite clover can be frost seeded (in early spring when the soil is still honeycombed with frost) into existing grass pastures to improve pasture production and quality. This technique requires that seeding be done while the soil contains frost.
