Summersweet is most useful when the garden already offers the moisture it needs, with room for a loose planting to develop.","h":[5,10],"w":[4,6],"install":[2,1.5],"color":"#74925c","habit":"upright","light":"Sun to part shade","lightTags":["sun","part"],"water":"Moist, acidic soil; tolerates occasional freshwater wetness","season":"Deciduous · fragrant white summer flowers; possible yellow fall color","care":"Manage spreading shoots; prune in winter or early spring if needed","site":"Consider a moist, sheltered Pensacola-area border or woodland edge. It is a poor match for a hot, dry bed. Freshwater moisture tolerance does not mean it belongs in brackish flooding or replaces a drainage plan.","sizeNote":"This full-species guide uses NC State’s 5–10 ft height and 4–6 ft spread; FNPS describes a broader 3–10 × 2–5 ft range. Spreading shoots can create a colony beyond one crown.

Use that information to choose the planting zone before adding a thirsty shrub to a dry landscape."],["Leave room for a colony.","Summersweet can spread by new shoots. Decide whether the bed will naturalize or whether edge maintenance is part of the plan."],["Enjoy the flowers beside the activity.","Place a fragrant planting where it can be appreciated while leaving circulation around seating open. Pollinator activity is another reason to avoid crowding a doorway."],["Show the off-season view.","Winter branches are part of this plant’s character. Add separately spaced evergreen structure if the border needs a green background all year."]],"faq":[["Is this the dwarf Hummingbird variety?","No. This guide covers Clethra alnifolia as a full-sized species. Check the exact cultivar tag before using its dimensions on a plan."],["Will it solve a drainage problem?","A moisture-tolerant plant does not establish where stormwater should go. Plan water movement first, then use plants suited to the resulting conditions."],["Can it grow beside a hot paved patio?","Only if the real growing conditions work. A dry, reflected-heat strip is a poor fit; a moist border with some shelter is a better starting point."]],"sources":[["NC State Extension · species size, summer flowers and care","https://plants.ces.ncsu.edu/plants/clethra-alnifolia/"],["Florida Native Plant Society · Florida site and moisture guidance","https://www.fnps.org/plant/clethra-alnifolia"]],"companions":[{"slug":"henrys-garnet-sweetspire","name":"Henry’s Garnet Sweetspire","title":"Layer two flowering seasons.","reason":"Henry’s Garnet sweetspire can add spring flowers in a similarly moist bed.
