British botanical writer and illustrator whose popular gardening manuals played a significant role in shaping nineteenth-century domestic horticulture. Though not formally trained as a botanical artist, she became widely known for her clear, accessible texts accompanied by hand-coloured lithographic plates intended for amateur gardeners, especially women.
Born Jane Webb in Birmingham, she first gained attention as a writer of imaginative fiction before turning to horticulture. Her interest in botany developed after reading the works of the landscape gardener and horticultural reformer John Claudius Loudon, whom she later married in 1831. Under his encouragement she began writing practical gardening books aimed at a growing middle-class readership eager to cultivate ornamental plants in gardens, conservatories, and greenhouses.
Her most influential works include The Ladies’ Flower-Garden of Ornamental Greenhouse Plants (1848), The Ladies’ Flower-Garden of Ornamental Annuals (1840), and related volumes.
