George Jackman II (1837–1887) was an English horticulturist and nurseryman, known for his work on early clematis hybrids.
In the late 1880s the land was sold for development, and the business moved to a new site nearby, where it survives as Woking Garden Centre, in the "Garden Club" chain.
[2] George Junior and his father started to hybridise Clematis in July 1858.
[1] Clematis 'Jackmanii' resulted from the first batch, and was awarded the Royal horticultural Society's First Class Certificate in August 1863.
[1] With Thomas Moore, he co-authored The Clematis as a Garden Flower (1872; revised 1877).
