The foliage is also complemented bydelicate peak spikesthat rise above the leaves in summer , bring out white or lavender blossom that attract pollinators . These versatile plant life work brilliantly as ground cover under trees , as specimen plants in container , or mass together to create dramatic textural displays in shaded borderline .
You ’ll find hostas particularly reinforce for problem area where few other ornamental thrive , such as deep shade beneath mature trees or north - facing wall . Their foliage emerges inspring , unfurling to reveal their full luster , and remain attractive until fall frost . While they favor rich , well - drainingsoil , their adaptability makes them forgiving of various soil type as long as they receive adequate wet and protection from harsh direct sun .
