'Blue Deckle', the petals on the sterile flowers are variously serrated, and at times give a distinctly frilly appearance, an elegant plant. Flower color is pale pink to lavender in neutral soils, blue in acid soil. Leaves turn reddish in the fall.
'Grayswood', the lacecap inflorescences have pale blue fertile to white sterile flowers changing to crimson red in fall. Leaves can be splashed pale green and darker green.
'MAKD' Tiny Tuff Stuff TM. One of the shortest lacecap hydrangeas, with double sterile flowers. Selected for improved bud and stem hardiness, it also consistently reblooms. Flower color ranges to soft shades of blue, pink, or white depending on soil pH, then age to pink.
'Miyama Yae-Murasaki', unusual lacecap clusters have double flowers ranging from rich purple to blue. This selection was first introduced as 'Purple Tiers'. Early blooming.
'Preziosa', globose flower clusters display progression of colors, from white, to pink rose, to purplish red by late summer. Dark maroon stems contrast well with the green leaves that turn red to purple in the fall.
