Plant Combination: Azalea (Rhododendron) ‘Delaware Valley White’ and Hosta undulata ‘Albomarginata’

azalea-hosta combinationMake spring time special with the combination featuring a white azalea and a hosta with a white edge. This hosta is one of the earliest to emerge so will be showing off its emerald green leaves with margins that echo the color of the azalea. After the azalea has finished blooming the hosta continues into fall producing pale purple flowers on arching scapes in mid-summer. The azalea leaves turn yellow in fall and persist through the winter while the hosta dies back for winter dormancy. Both plants enjoy part shade and moist, well-drained soil.
