After marriage to John Loudon in 1830, a Scottish botanist, garden designer and author, she re-focused her writing skills onto supporting his works and also writing her own books and periodicals. She had no previous experience in this area and commented, “It is scarcely possible to imagine any person more completely ignorant of everything relating to botany than I was at the period of my marriage with Mr Loudon.” She took on an assistant role to her much older husband. She planted and maintained the gardens at their home in London, and cared for the plants meticulously in order for him to be able to do his research. With her own writing experience, she assisted him in editing his publications, in particular his extensive
Encyclopedia of Gardening (1834). They travelled together in England and Scotland the 1830s and early 1840s as he advised on gardens, estate design and obtained for plant material for his books and periodicals. She also attended public lectures in London by
John Lindley to improve her knowledge and provide material. Jane worked closely with her husband for the remainder of his career; they believed gardens were a work of art, as well as manifestations of science. She realized there was a major gap in the market for easy to understand gardening manuals. At the time, all articles were written at a level for those already in the field, and manuals were too technical for the everyday person to understand. With her husband producing these intellectual works it gave her a resource to make gardening understandable and accessible. Her first books were published in 1840 as the cost of illustrations of her husband's book
Arboretum et Fruticetum Britannicum put the family into crippling debt. Jane Loudon wrote gardening books illustrated with her own botanical artwork. Jane Loudon's books gave women hope and power to be able to complete the task of gardening while getting helpful hints on how to do this effectively from her works. She wrote the following books: • ''Young Lady's Book of Botany'' (1838) •
Agnes, or the Little Girl who Kept a Promise (1839) •
Instructions in Gardening for Ladies (1840) •
Gardening for Ladies and Companion to the Flower Garden (1840) • ''Ladies' Flower-Garden of Ornamental Annuals'' (Four volumes 1840 - 1848) • ''The Young Naturalist's Journey: or the Travels of Agnes Merton and Her Mama'' (1840) • ''The Ladies' Flower Garden or Ornamental Bulbous Plants'' (1841) •
The First Book of Botany … for Schools and Young Persons (1841) •
The Ladies Companion to the Flower Garden. Being an Alphabetical Arrangement of all the Ornamental Plants Usually Grown in Gardens and Shrubberies (1841) •
Botany for Ladies or, a Popular Introduction to the Natural System of Plants (1842) •
British Wild Flowers (1845) • ''The Lady's Country Companion or how to enjoy a Country Life Rationally''(1845) • ''Amateur Gardener's Calendar'' (1847) • ''Lady's Country Companion at Home and Abroad'' (edited between 1849 and 1851) • ''The Ladies' Flower-Garden of Ornamental Greenhouse Plants'' (1848) •
Tales About Plants (1853) • ''My Own Garden Or, The Young Gardener's Year Book'' (1855) Several of these books were very successful;
Gardening for Ladies and Companion to the Flower Garden sold 1350 copies on the day it was published in 1840. She founded the periodical
The Ladies Magazine of Gardening in 1842. In late 1849 Loudon began editing ''The Ladies' Companion at Home and Abroad'', a new magazine for women. Successful at first, its sales fell and she resigned. All of these works taught women how to create beautiful gardens, and also enlightened them by giving them "work" to do in a time where they were not allowed to do such tasks. She was encouraged in writing these books by the horticulturalist
John Lindley. ==Botanical artist==
