A weeping, mound-forming laceleaf Japanese maple with finely cut deep red-purple foliage that holds its color through summer better than most, turning bright scarlet in fall.

A weeping, mound-forming laceleaf Japanese maple, wider than tall at maturity, with finely dissected deep red-purple foliage. It's one of the oldest known dissectum cultivars — widely cited as dating to around 1710 in Japan, though that date is repeated across nursery sources rather than tied to a single documented primary source. Foliage emerges crimson-red in spring and, unlike many red laceleafs that fade to green or bronze by midsummer, holds a dark purple-red color into late summer before turning bright scarlet in fall. Small reddish-purple flowers appear in spring, followed by winged samaras. Best sited in part shade with wind protection — full sun can scorch the foliage in hot climates, and its early leaf-out makes new growth vulnerable to late spring frost. As a grafted cultivar, it doesn't come true from seed and is propagated onto seedling Acer palmatum rootstock.

Pros

  • Holds deep red-purple foliage color through summer better than most red laceleaf maples
  • Reliable bright scarlet fall color
  • Graceful weeping, mounding form; classic choice near water features or in Japanese-style gardens
  • Slow, compact growth suits small spaces and container growing

Cons

  • Needs wind-protected, part-shade siting — full sun can scorch foliage in hot climates
  • Early leaf-out is vulnerable to late spring frost
  • Susceptible to verticillium wilt and leaf scorch under stress
  • Not drought-tolerant; needs consistent moisture
Highlights One of the oldest known laceleaf Japanese maple cultivars (reportedly dating to around 1710), prized for holding its deep red-purple color through summer better than most; graceful weeping form classically used beside water features.

Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
