| Vegetative structure that consists of layers or fleshy scales overlapping each other | Bulb |
| Immature bulb that develops at the base of the bulb | Bulblets |
| Pull bulbs or corms of monocots deeper in the soil through expanding radially and contracting longitudinally | Contractile Roots |
| Swollen underground stem that grows upright | Corm |
| A new corm produced by a larger corm | Cormel |
| Method of propagation requiring the cutting and dividing of plants | Division |
| Occurs when second year of growth occurs and a second flower bud forms and the bulb is then capable of producing two flower stalks | Double-Nose |
| Stems are soft or succulent and green, as opposed to brown and woody. Generally soft, green, herbaceous growth will die back to the ground in cold, winter climates. The roots of the perennial plant are alive and well and new growth will emerge in the spring | Herbaceous Perennial |
| A second bulb that forms around the original bulb | Offset Bulb |
| Tendency of tuberous roots to grow shoots on one end, or the top, and roots on the other end, or bottom | Polarity |
| Underground stem that produces roots on the lower surface and extends leaves and flowering shoots above the ground | Rhizomes |
| Method of propagation that occurs naturally in which reproductive organs of a plant detach from the parent plant to become new plants | Separation |
| An offset bulb when it is first separated from the mother bulb | Split or Slab |
| Fleshy root that reproduces by growing roots from an eye, or bud | Tuber |
| Thick root containing large amounts of stored food | Tuberous Roots |
| Thin, green, actively growing tissue located between the bark and wood of a plant; in grafting, the cambium of he scion must touch the cambium of the stock | Cambium |
| Ability to unite with, grow, and live together, like the scion and rootstock in the grafting and budding processes | Compatibility |
| Uniting two different plants so that they grow as one | Grafting |
| The lower portion of a graft that becomes the stem and roots of the new plant | Rootstock |
| A short piece of shoot containing several buds that becomes the new top of a grafted plant | Scion |
| A short piece of shoot containing several buds that becomes the new top of a grafted plant | Stenting |
| A type of grafting where a single bud is used to produce the top part of the plant | Budding |
| The bud and piece of wood and bark cut to be inserted under the bark of the rootstock | Bud shield |
| Current season growth of wood selected from plants chosen to be propagated by budding | Budwood |
| The lower portion of a graft that becomes the stem and roots of the new plant | Rootstock |
| A bud that will grow into a stem or shoot, not a flower | Vegetative Bud |
| A process where stems still attached to the mother plant are rooted in the air instead of being covered with soil | Air Layering |
| A system where a stem or vine is covered at more than one place along its length for rooting, otherwise the same as simple layering | Compound Layering |
| To remove all the cambium and bark from a stem for a short distance to aid in rooting | Girdle |
| A lower branch from a plant is bent to the ground where it is partially covered with soil for rooting of new shoots | Simple Layering |
| The parent plant is cut back to near soil level and covered with soil; new shoots root as they emerge from the parent plant and rise above soil level | Stool Layering |
| A plant is bent over and the branches of the entire plant are buried with soil in a trench; roots develop as new shoots form and grow up above the soil level | Trench Layering |
