Complete question: if i need to clone a plant in about a month and a half and have no idea how long it will take or what i should use.my book said coleus plants are easy to root.is this true?it also saidthat i could use chrysanthymums,philodendrons,ivys,african violets,begonias,and geraniums were good.on a different site it said that daffodils were good but took longer but it didnt say how long. Reply: Other terms for plant cloning are asexual propagation and vegetative propagation. The easiest to root in your list is philodendron because it has root initials at the stem nodes so all the roots have to do is elongate. Be careful with philodendron cuttings because the sap can cause a poison ivy like rash because of tiny but sharp calcium oxalate crystals. I know that from personal experience. Coleus shoots are also easy to root in water. African violet leaves root easily but it may take months for a new shoot bud to develop from the rooted leaf. The others in your list are fairly easy but you would probably want to use a rooting hormone on the shoot cuttings. Daffodils are cloned by dividing the bulbs rather than with shoot cuttings. One of the easiest and fastest houseplants to clone are the several kinds of wandering jews (Tradescantia and Zebrina species) which also have root initials that can elongate 1 cm per day in water. Perhaps the fastest and easiest houseplant to clone is mother-of-thousands or devil's backbone (Kalanchoe daigremontiana) from Madagascar which forms hundreds of tiny, rooted plantlets on the edges of its leaves. Simply pluck them off and drop the plantlets on soil. Another houseplant, piggyback plant (Tolmiea menziesii) is native to the Pacific northwest and also forms plantlets on leaves.
