Baccharis halimifolia - Aster Tree, Snow Bush

Growth habit: This plant grows into a small to medium tree, about 10 to 20 feet tall when planted in the ground. It works well in gardens or yards with room to spread, but it can also be pruned to stay smaller and may be grown in a large pot with proper care.

Growing conditions: This plant can be grown outdoors in the suitable USDA zone. It is well-suited for small backyards, pots, or indoor spaces with enough light.

Watering: This plant requires regular watering. Water it when the top layer of soil begins to dry out.

Flood tolerance: This plant can tolerate occasional flooding or very wet soil, making it suitable for low-lying areas.

Sun exposure: This plant grows well in both full sun and semi-shade. If kept indoors, give it as much light as possible for best growth.

USDA Zone: Zone 9-11. The USDA Plant Hardiness Zone Map categorizes North America into zones based on average annual minimum winter temperatures, each differing by 10 °F. This map serves as a basic guide for selecting appropriate plants for a region. However, it's not definitive; plant varieties vary in cold tolerance, and young plants typically need more protection. Additionally, local microclimates, like sheltered areas or sunny spots, can influence plant health and survivability beyond the general zone recommendation.

Hardiness: Light freezing, 30°F for short period of time, mature plants. Young plants must be protected. Plant hardiness indicates the coldest temperature a mature plant can endure briefly while staying healthy. This rating is a guideline and can vary among varieties of the same species. Young plants often need more cold protection. Additionally, a plant's survival can be enhanced by the microclimate of its location, which may provide shelter from wind or extra warmth, allowing it to thrive beyond its typical hardiness range.

Flower color: This plant produces white and off-white flowers during its blooming season.

Butterfly attractor: This plant attracts butterflies and hummingbirds, making it a great choice for pollinator-friendly gardens.

Plant in well-draining soil and choose a location that matches the plant light and space needs. Improve poor soils by mixing in compost or organic matter. Dig a hole twice as wide and no deeper than the root ball - planting too deep can harm the plant. For better drainage, position the plant so the top of the root ball is slightly above ground level. Water thoroughly after planting. Outdoor plants may need temporary shade during the first weeks to protect them from strong sun or heat. Watch the soil moisture closely and water regularly until the plant is well established. Apply mulch around the base to help retain moisture and reduce weeds, forming a shallow basin to hold water. Keep mulch a few inches away from the trunk or stem to prevent rot.

Use a container with drainage holes and a well-draining potting mix. Position the plant so that the top of the root ball is level with the surface of the soil - avoid planting too deep. A slow-release fertilizer can be mixed into the soil at planting time to support healthy growth. Place the plant in a location that matches its light needs, and water according to its care requirements. Be careful not to overwater, and ensure good airflow around the plant to reduce the risk of pests and disease.
