Overwintering Bracteantha (Strawflower) in New Jersey: Container Strategy

Bracteantha (Xerochrysum bracteatum), native to Australia, is hardy only in zones 8–11. In northern New Jersey (zone 6–7), it must be treated as an annual or overwintered in containers.

Container Overwintering Method

1. Before frost: Move pots to unheated garage (35–45°F ideal).
2. Water sparingly—once monthly, just to prevent desiccation.
3. No fertilizer during dormancy.
4. After last frost: Gradually reintroduce to outdoors; resume watering/feeding.

Alternative: Grow as Annual

Start fresh each spring from seed or nursery plants. 'Jumbo Yellow' and other cultivars bloom prolifically all summer with minimal care in full sun.

Key Requirements

• Excellent drainage (add perlite to potting mix).
• Full sun (6+ hours).
• Deadhead for continuous bloom.

While not garden-hardy in NJ, bracteantha rewards container gardeners with everlasting papery flowers.
