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:

DescriptionTiny Quick Fire™ Panicle Hydrangea (Hydrangea paniculata) may be our smallest panicle hydrangea, but it doesn't skimp on flowers. Strong stems hold an abundance of massive blooms, starting as early as May and continuing into the fall. Color-changing flowers follow the season, transitioning from early summer white to an array of pink and red tones in the fall. If that wasn't enough to convince you, the flower shape might! The petals are cupped, making each floret resemble a tiny bowl for pollinators to feast from.
Panicle hydrangeas are one of the easiest hydrangeas to grow, making them perfect for beginners. They bloom on new wood, which means they reliably flower each year (even after cold winters). All they need is a quick prune in early spring for a floriferous year! DetailsBotanical name:Hydrangea paniculata 'SMNHPSB' Patent #: PP#34,468 Common name: hydrangea, Peegee hydrangea, Hardy hydrangea Zone: 3-8 Sun exposure: Sun (6+ hours sun) in cool areas; part-sun (4-6 hours sun) in warm climates. Height x width: 1.5-3' tall and 2 - 3' wide Flower color: White, turning red in autumn Foliage color: Green Season of Interest: Summer-fall Bloom time: Summer Features: Space savers, proven winners, container plants, cold tolerant, best sellers, best for beginners Uses: Flower gardens, landscaping, specimen, flowering hedge How To GrowSoil: Panicle hydrangeas require well-drained soil. Though they are the most sun and drought tolerant of all hydrangeas, for best performance, don't let them dry out excessively. A good layer of mulch is very helpful for minimizing drought stress and conserving moisture. Light: plants can take full sun (6+ hrs/day) in cooler areas, but afternoon shade is recommended in warm climates. If your plant frequently wilts in the afternoon even though it was recently watered, or your flowers turn brown quickly, that may indicate the spot is too sunny for it. Water: Average. Panicle hydrangeas do not tolerate overwatering or poor drainage. Space: Min. 6' apart Fertilizing: If desired, fertilize in early spring, once the ground has thawed, with a granular rose fertilizer. Winterizing: Panicle hydrangeas are very hardy and easily withstand harsh winters, so need no special care. A good 2-3" layer of mulch helps protect the shallow roots. We recommend pruning in late winter/early spring (see below for more info) but plants can be pruned in late autumn, after they've gone completely dormant, if desired. Maintenance: Panicle hydrangeas bloom on new wood; that means they create their flower buds after leafing out in spring, so they can be pruned and will still bloom that season. While pruning is not strictly necessary, it does neaten the plant's appearance and can help develop strongest stems. Simply cut the main stems of the plant back by about one-third its total height in late winter or early spring, removing any thin or spindly or wayward branches as necessary.
