The Young Plants team has brought the fuchsia plants through a difficult winter, during which snow blocked the road to their Stratford site and prevented staff getting to work many times during February.
A member of its trials team, Lynne Smith, has been dedicated to caring for the fuchsias to ensure they are in perfect condition when unveiled this spring.
Smith said: "It has been a lot of effort and sleepless nights but we know it was worthwhile, now the plants are looking so good.'
After Peter Seabrook asked Young Plants to produce the plants the young plant supplier consulted specialist fuchsia growers Doug Jones of Roualeyn Fuchsias and Mike Clare of Potash nurseries.
"Both are previous medal winners at Chelsea and all of their advice has been invaluable to us' said Young Plants trials supervisor Sally Newbury.
The team potted the plants early in autumn and got electricians to hang new lighting in the trials house.
Young Plants managing director Alex Newey said: "We are all really excited to be showing our Celebrity Fuchsias at Chelsea and we are grateful to Peter for his selection and support."
