Greater purple fringed orchid is a stunning native wildflower that produces tall spikes of fragrant, deeply fringed purple flowers from June through August. This elegant perennial thrives in partial shade with consistent moisture and goes dormant in winter, disappearing completely until the following growing season.
In an HOA neighborhood

Wildlife value
The fragrant blooms are specifically adapted to attract night-flying moths and butterflies with their long spurs and sweet scent. This orchid is particularly valuable for supporting native sphinx moths and other long-tongued pollinators.
