Key Facts
- Native to the Atlantic and Gulf coastal plain of eastern North America
- Deciduous to semi evergreen shrub depending on winter severity
- Produces fluffy white seedheads in late summer and fall
- Tolerates salt spray and poorly drained soils
- Attracts pollinators including bees and butterflies
- Can spread by windborne seed and form dense thickets in warm regions
- Propagated from seed and from cuttings
Eastern Baccharis is a coastal North American shrub used for salt tolerant hedges and pollinator patches, flowering in late summer and fall with conspicuous fluffy white seedheads. It tolerates wet, brackish and sandy soils but can spread by windborne seed and form dense thickets in warm regions.
Identification and key traits
Deciduous to semi evergreen depending on winter severity, Eastern Baccharis typically reaches about 6 to 12 feet tall and spreads 6 to 10 feet. Look for narrow leaves and abundant white, fluffy seedheads in late summer to fall that persist and disperse by wind. Alternate names include saltbush, sea myrtle and groundsel tree.
Where to grow and best uses
Native to the Atlantic and Gulf coastal plain, this shrub performs well in coastal plantings and salt‑exposed borders where many shrubs struggle. Use it for informal screening, native pollinator patches or sites with poorly drained, brackish or sandy soils. Warmer zones favor faster growth and a greater tendency to naturalize.
Planting and propagation
Plant container grown or balled specimens during the active growing season, avoiding hard freezes. Space plants roughly 6 to 10 feet apart to match mature spread in hedges or thickets. Propagate by seed or stem cuttings; semi ripe and hardwood cuttings root readily and seed will self seed where it naturalizes.
Soil, light and watering
Prefers moist to wet soils but tolerates well drained sandy and brackish substrates and a range of pH including alkaline. Best in full sun to partial shade. It tolerates salt spray and poorly drained sites. Long drought or very dry compacted soils reduce vigor and slow growth.
After flowering care and pruning
Seedheads appear in late summer and fall and release windborne seed. To reduce volunteer seedlings remove seedheads or deadhead before seeds mature. Light formative pruning maintains shape. In colder areas winter dieback may occur and selective pruning to healthy wood encourages regrowth in spring.
Controlling spread and invasiveness
Eastern Baccharis readily spreads by abundant wind dispersed seed and can form dense thickets in warm coastal regions. Check local invasive species lists before planting. Reduce seed production by cutting back flowered stems and remove young volunteers to prevent colonies beyond intended planting areas.
Safety and wildlife value
The shrub attracts pollinators including bees and butterflies when in bloom. Some Baccharis species can cause contact dermatitis in sensitive people and ingestion may cause mild gastrointestinal upset in pets or people. Confirm species specific toxicity with local extension or poison control if handling or planting near animals.
Frequently asked questions
- How fast does Eastern Baccharis grow?
- Growth rate varies by climate and site. In warm coastal sites it grows faster and reaches its common mature height of 6 to 12 feet; colder winters often slow top growth or cause seasonal dieback.
- Is Eastern Baccharis invasive?
- It can naturalize and form dense thickets in warm regions due to windborne seed. Check regional invasive species lists before planting and manage seedheads to limit spread.
- Can I plant Eastern Baccharis near the coast?
- Yes. It is well suited to coastal conditions, tolerating salt spray, brackish soils and poorly drained sandy sites, making it a good choice for salt tolerant borders and coastal hedging.
- How do I propagate Eastern Baccharis?
- Propagate from seed or stem cuttings. Semi ripe and hardwood cuttings root readily in many conditions. Seeds are wind dispersed and will readily produce volunteers where established.
- Does Eastern Baccharis harm pets or people?
- Some people may experience skin irritation on contact and ingestion can cause digestive upset. It is not widely reported as highly toxic to pets, but verify risks with local poison control or extension resources before planting near animals.
