9 cm sized pot.  Chrysanthemum Kelvin Mandarin is a favourite of mine with it's flower buds emerging in a bright tangerine colour then as they age the flower becomes more pompom like and takes on a rusty tone.  Very eye-catching autumn flower display.  Fantastic as a cut flower.  Reaches 1m tall, would require support if you don't want them flopping around.  Loves a sunny position in well-drained soil
