Read the first 6 LARE Plants and Planting Design flashcards as text

  1. Which term describes a plant that completes its entire life cycle within one growing season?

    Answer: Annual

    An annual completes germination, growth, flowering, seed set, and death within a single growing season.

  2. On a LARE planting plan, what does a plant's 'caliper' measurement refer to?

    Answer: Diameter of the trunk measured 6 inches above ground

    Caliper is the trunk diameter of a tree, typically measured 6 inches above the ground for trees up to 4-inch caliper.

  3. Which USDA hardiness zone system do US landscape architects primarily reference when selecting plants for cold tolerance?

    Answer: USDA Plant Hardiness Zone Map

    The USDA Plant Hardiness Zone Map, based on average annual minimum temperatures, is the standard reference for cold tolerance in plant selection.

  4. What is a 'climax community' in the context of landscape succession?

    Answer: The stable, long-term plant community that develops after succession

    A climax community is the stable, self-perpetuating plant community that represents the endpoint of ecological succession in a given region.

  5. Which planting zone specification best ensures plant survival when installing trees in urban heat islands?

    Answer: Select plants rated one zone warmer than the site's USDA zone

    Urban heat islands elevate temperatures, so specifying plants rated for one zone warmer provides resilience against the higher ambient heat.

  6. In planting design, what is the primary benefit of specifying a 'B&B' (balled and burlapped) tree over a container-grown tree of the same species?

    Answer: Larger available sizes for established specimens

    B&B trees are available in larger caliper sizes than container-grown trees, making them preferable when an immediate, established appearance is required.
