This new variety was found by Crispin Silva as a colourful mutation on Ginkgo biloba  'Jagged Jade' was introduced into the trade in 2016. Like so many variegated cultivars this shows enormous promise. It is hoped that the variegation remains stable. Already there has appeared a sport (a genetic mutation) of Ginkgo biloba ‘Crispin's Jaded Jester’, with a greater degree of yellow in the leaves and less green, this will be a weaker plant and may or may not prove to be stable.

Description - Ginkgo biloba ‘Crispin's Jaded Jester’ syn. ‘Jaded Jester’ is an incredibly attractive new cultivar. It has dark, rubbery, blue-green leaves are streaked with golden yellow. The growth rate is slow, it grows 7.5cm - 12.5 cm a year. It is too early to say what the overall habit and dimensions are likely to be, but it is estimated that it could possibly reach 2m in height and spread in 10 years. It is recommended that it is grown in slight shade and should any shoots revert to ‘plain green’, they should be removed.
