Even if they never flowered, there are Salvias we would grow for their showy foliage. Some branch in a pleasing way or have colorful stems. Others have leaves that are large and textured, uniquely shaped, variegated, bicolored or pleasingly fuzzy.
(Hidalgo or 7-UP Plant) I love to ask people what the smell of these leaves remind them of. Almost no one gets it on the first try, but when I say, "7 UP", their eyes light up, heads nod and the resounding answer is, "Yes!"
