Seacliff Beggarticks: A Rare Hawaiian Native Worth Protecting

If you’re passionate about native Hawaiian plants and conservation gardening, you may have come across the seacliff beggarticks (Bidens hillebrandiana hillebrandiana). This little-known perennial shrub represents one of Hawaii’s most precious botanical treasures – and one of its most vulnerable.

What Makes Seacliff Beggarticks Special

The seacliff beggarticks is a charming low-growing shrub that stays naturally compact, typically reaching just 1.5 feet tall and rarely exceeding 3 feet at maturity.
