Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

DescriptionWith pink cup-shaped flowers that dance in the breeze, 'Robustissima' Japanese anemone is a mesmerizing addition to the landscape. It blooms in late summer and early fall on tall, wiry stems, making the flowers appear to float above clumps of dark green foliage. Despite its delicate appearance, 'Robustissima' is highly robust and easy to grow. It's a reliable bloomer that tolerates more sun and drier conditions than other cultivars.
You may think of anemones as spring bloomers, but Japanese anemones flower in late summer and fall. Just as your other perennials start to fade, Japanese anemones shine with tall stems and satiny flowers. They're a magnet for pollinators - and thankfully, they remain unbothered by deer and rabbits. They're easy to grow, making them even easier to love in your landscape, containers, or cut arrangements.
Great garden tip: be patient in spring! They're a bit slow to rise in spring but arrive just in time to fill in around dying spring bulbs.DetailsBotanical name:Anemone tomentosa ‘Robustissima’ Common name: Japanese anemone Zone: 4-8 Sun exposure: Sun (6+ hours sun) to part sun (4-6 hours sun) Height x width: 3-4' tall x 2' wide Flower color: Light pink Foliage color: Green Season of interest: Summer and fall Bloom time: Summer, fall Features: Rain gardens, rabbit resistant, heat tolerant, deer resistant, container plants, best for beginners Uses: Border plant, mass planting, container plantings, cut flower, cottage garden, pollinator gardenHow To GrowSoil: Rich, loose, well-draining soil with consistent moisture is preferred. Light: Sun (6+ hours sun) to part sun (4-6 hours sun). They can be grown in full sun in cool climates as long as the soil stays moist. Warmer climates should grow them in part sun, where they receive shade in the afternoon. Water: Requires consistently moist soil but does not tolerate standing water. Water frequently with a light hand. Spacing: 1.5 - 2 feet. Fertilizing: Apply a slow-release fertilizer in spring for the best performance. Winterizing: Apply an extra layer of mulch in the fall to prevent frost heaving. Maintenance & pruning: Typically a low maintenance perennial with few pest or disease problems. Routinely deadhead to encourage more blooms. Plants may slowly spread by rhizomes, which can be easily transplanted to new areas if desired.
