Rudbeckia
Rudbeckia is the golden daisy of high summer and early autumn, instantly recognisable by its warm yellow-to-bronze rays circling a dark, domed cone. Florists prize it as a cheerful, sturdy focal that carries meadow and prairie-style designs without fuss. Its colour range spans clear yellow through mahogany and rust, making it a natural fit for late-season and rustic palettes. Reliable, inexpensive and long-lasting, it bridges the gap between sunflowers and the finer autumn daisies.

Cut stems on a sharp angle and place immediately into clean, cool water with flower food. Strip all foliage that would sit below the waterline, as rudbeckia leaves foul water quickly. Give the stems a deep drink in a cool room for a few hours before arranging, and refresh the water every two days to extend the display.
