Dandelion coffee Dandelion coffee Dandelion 'coffee' (also dandelion tea) is herbal tea used as a coffee substitute, made from the root of the dandelion plant. The roasted dandelion root pieces and the beverage have some resemblance to coffee in appearance and taste. Susanna Moodie explained how to prepare dandelion 'coffee' in her memoir of living in Canada, "Roughing it in the Bush" (1852), where she mentions that she had heard of it from an article published in the 1830s in "New York Albion" by a certain Dr. Harrison. Dandelion 'coffee' was later mentioned in a "Harpers New Monthly Magazine" story in 1886.
Plant development roots and buds are very important when people propagate plants via cuttings, layering, tissue culture. Plant hormones, termed auxins, are often applied to stem, shoot or leaf cuttings to promote adventitious root formation, e.g. African violet and sedum leaves and shoots of poinsettia and coleus. Propagation via root cuttings requires adventitious bud formation, e.g. in horseradish and apple. In layering, adventitious roots are formed on aerial stems before the stem section is removed to make a new plant. Large houseplants are often propagated by air layering. Adventitious roots and buds must develop in tissue culture propagation of plants. The genetics
