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:

DescriptionA forsythia for plant collectors? Yes! Flying Machine forsythia (Forsythia koreana) is quite unlike any you may have seen before. Its flowers are absolutely gigantic - at least twice the size of a regular forsythia - and festoon the branches with garlands of bright gold through spring. The magic doesn't stop there, though. When the flowers fall, they spiral to the ground and create a magical yellow carpet below the plant, freckling the ground (and any bulbs or perennials you have nearby!) with color. This may seem like a minor feature, but it has significant impact in the garden. We think it will charm you just as much as it did us.
Forsythia aren't just beautiful harbingers of spring - they're also super durable landscape plants, readily growing in difficult soils, even clay. They are unbothered by deer and rabbits and can even grow in shade (though do note that if plants get fewer than four hours of sun, flowering will not be as spectacular).DetailsBotanical name: Forsythia koreana 'Sunny' Common name: Forsythia Zone: 6 - 8 Sun exposure: Sun (> 6 hours sun) to part sun (4-6 hours sun) Height x width: 5-8 ft tall x 4-6 ft wide Flower color: Yellow Foliage color: Green Season of interest: Winter/spring Uses: Accent, Border, Container gardening, Erosion control or embankment, Foundation planting, Hedge, Massing, Naturalize, Ornamental, Small spaces How To GrowSoil: Very adaptable to a wide range of soils. Highly tolerant of clay. Established plants readily tolerate dry conditions. Light: Sun to partial shade. Can grow in deep shade, but flowering will be severely compromised. Water: Average water needs. Water regularly; do not overwater. Spacing: 6' Fertilizing: Nothing special required. If you want plants to grow more quickly, an application of granular rose fertilizer can be applied in early spring, and again in late spring if desired. Winterizing: No specific care needed, though a good 2-3" layer of shredded bark mulch is beneficial. Branches may be clipped and brought indoors for winter blooms beginning in early-mid February. Maintenance & pruning: This does not require regular pruning. If you wish to prune, do so in late spring, immediately after it finishes blooming.
