The special displays were introduced on 9 November and could last beyond the end of the month if the plants thrive in the glasshouse.
Wisley has tended the plants for 10 months and gardener Paul Atkinson has given them extra care.
"To display the new varieties alongside our existing Japanese Chrysanthemum we had to use a blacking system to try to bring forward the normal flowering period," said Atkinson. "This involved shortening the number of daylight hours that the plants were exposed to, which encouraged them to bloom a couple of weeks early."
The charm and cascade chrysanthemums will be shown alongside a selection of Japanese varieties, including the spider flower variety.
The Wisley collection includes 100 varieties and the special 2009 display is open to the general public from 10am to 3.45pm daily.
