Ramsey is often incorrectly called Salt Creek and was selected by T.V. Munson in Texas. The true Salt Creek is a selection of V. doaniana, a closely related species. Ramsey is thought to be a natural hybrid between V. candicans and V. rupestris, and like Dog Ridge, it induces very high vigor in scions (although slightly less than Dog Ridge). This rootstock is well suited to low fertility, coarse-textured soils, and it has strong resistance to root-knot nematodes. It is not recommended for premium wine grapes, and coastal growers should consider other rootstocks for general nematode control. The leaves of Ramsey are distinguished from Dog Ridge by being less lobed, and by having sharper teeth and tendrils that are more yellow. It is also a female vine.
