Harvest Tips
Sweet Wattle is grown primarily for ornamental and fragrance value rather than harvesting. Cut flowers can be harvested early morning when buds are opening; they last 1-2 weeks in a vase. Cut fresh sprigs as desired for dried flower arrangements or fragrant decorative use. For seed collection, allow flowers to develop into curved seed pods; harvest when pods mature to brown and dry naturally.
