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 uniquely variegated foliage and flower-like bracts, 'Ascot Rainbow' spurge (or Euphorbia x martinii ) is an intriguing perennial for colorful patio containers or sunny garden beds. Narrow, grey-green foliage has bright yellow margins from spring to fall, but it really shines in the cooler months. In cool temperatures, the foliage picks up red, pink, and orange hues, creating a kaleidoscope of colors on each leaf. As if it weren't already colorful enough, it boasts dark purple stems and variegated flower-like bracts in late spring. It's the perfect plant for variegated plant collectors or any gardener that needs to add flair to their landscape!
Spurges are shrub-like perennials that are easy to grow for gardeners of any level, as long as they're planted in well-draining soils. It's tolerant of heat, drought, and even poor soils, making it ideal for problematic or xeric sites. Since it's resistant to deer, rabbits, and diseases, it takes very little (or no maintenance) to remain attractive all season long. Plant it in full sun in northern zones and part sun (with afternoon shade) in southern zones for the best performance.
Caution: spurges are a relative of poinsettias, so they are also poisonous if ingested by humans or pets. Handle with gloves, as their sap may irritate the skin.Details Botanical name: Euphorbia x martinii 'Ascot Rainbow' Common name: Cushion spurge Zone: 5 - 9 Sun exposure: Sun (> 6 hours sun)- part sun(4-6 hours sun) Height x width: 12-18" X 12-18" Flower color: Yellow Foliage color: Green Season of interest: Spring - fall Bloom time: Spring Features: Rabbit & deer resistant, heat tolerant, drought tolerant, cold tolerant Uses: Accent, border, container gardening, cottage gardening, foundation planting, massing, ornamental, specimen How To Grow Soil: Prefers dry, sharply-draining soils.
