| Name of Method | How it works: diagram? | Example Plant(s) |
|---|---|---|
| Epiphyllous Buds |
Cytokinins in leaf edges cause formation of shoot Auxins from shoot tip cause formation of roots Plantlets fall to soil as separate plant | Bryophyllum daigremontianum (maternity plant, mother of thousands), Piggy back plant |
| Scaly Bulb |
Bulb made of leaf bases attached to basal plate, roots are adventitious lateral buds between leaf layers at basal plate form bulbils in years where one bulb planted a clone of competitors develops | Onion, Tulip, Daffodil |
| Corm |
Like scaly bulb without layers, so just basal plate lateral buds on stem develop into cormels in years where one corm planted a clone of competitors develops | Crocus, Gladiolus |
| Tuber at end of Rhizome |
Late Summer leafless underground stems penetrate soil (rhizomes) Early Fall: tips of rhizomes swell into tuber Tuber has many lateral buds (eyes) that grow into separate plants | Potato, Helianthus tuberosus |
| Stolons with Crowns |
Plant produces leafless branch (stolon) Crown develops at end of stolon Weights tip to ground, roots, establishes clone | Spider plant, Strawberry |
| Tip Layer |
Normal Leafy Shoot Elongates Buries tip in soil Adventitious Roots form Shoot develops in Spring | Black Raspberry, Forsythia |
| Root Sprouts |
Roots of plant penetrate soil Some reach near soil surface Cytokinins accumulate and shoot forms | Red Raspberry, Rose, Most Shrubs |
