    Design IdeasThis stellar selection of native vine maple is ideally situated where dappled sunlight can stream through its graceful branching structure. Elegant entry-way accent,especially with up-lighting, so that the bright green lacy leaves can create a pattern against the architecture. Pair with an understory of large-leafed shade loving perennials or dwarf shrubs.
  • Care
    Care Information
    Adaptable to most soil types. Water regularly and deeply during the first growing season to establish a deep, extensive root system. Once established, give an occasional deep soaking during dry weather. Apply a slow-release fertilizer in spring. Mulch to protect shallow roots. Prune only as needed to remove dead wood.Pruning time: late winter to early spring.
    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).
