The chrysanthemum comes in a huge array of sizes, flower head numbers, petal shapes and colours, meaning there are thousands of varieties. Luckily, they're quite easy to spot as they look a lot like daisies - which is a cousin of theirs in the Asteraceae family.
The centre disc of the flower is often a different colour, much like the daisy, but there are some varieties that have short petals that hide it.
Their petals can also be long and spray out from the centre like a daisy, or they can also be densely packed around the centre, curled up like Dahlia petals. A variety called the spider mum has tubular petals that splay out, like spiders legs!
