Hosta: Wiggles and Squiggles1 Gallon Celebrated for its bright yellow slender foliage with incredibly wavy margins; its shorter, horizontal habit highlights the wiggly edges. For best yellow coloring, plant with morning sun and afternoon shade. Lavender flower scapes. Hosta thrive in shade, even in competition with tree roots, hurray! It is hard to find a perennial garden that wont benefit from incorporating some Hosta.
