WaratahT The Waratah, an iconic Australian native flower and official floral emblem of New South Wales, blooms best in spring and becomes an ideal cut bloom. Coming in an array of shades, including red, pink, yellow, white, and creamy white with a green centre, this beauty is truly beguiling. Take care when cutting the stems an inch shorter prior to arranging in a vase; don't forget to check the water level daily, since Waratahs have an insatiable thirst.
