Emerald Lace Japanese maple is a lovely laceleaf with finely dissected leaves. Emerald lace has leaves that emerge bright green in spring with red petioles that remain red throughout the season. Summer color lightens to light green with red highlights. Emerald lace has great fall colors that run yellow to orange and finish up with fiery red. Hardy and vigorous. Typical cascading habit. Height 5-6′ in 10 years and just as wide. Height can easily be maintained with thoughtful pinching back and conversely – can be trained higher by staking. Does great in sun, but in hot areas, provide some shade in the the afternoon. Cold hardy to -10F.
