  - similar in appearance, but store their nutrients in scales instead
* are special buds, and they are thick and fleshy
  - subterranean reserve structures derived from leaves
  - spotted and rot in the field or in storage
  - stalks
  - stems that are underground and are specialized in storing food

  - tall, bulbs are small
  - technically rhizomes, but they are sometimes listed separately
* are the easiest flowers to grow
  - most toxic part
  - size of a quarter
  - under grounded stems that are like a food storage
  - underground condensed shoots which have one or more buds
* are underground stems specialized for food storage
  - that have thickened leaf bases and store food
  - up just in time to have their flowers knocked down by hailstorms
  - used for blooms
* are usually globular and have concentric layers of fleshy leaves covering the short stem
  - most impressive when planted in clusters for color impact
* are very easy to grow
  - sensitive to most herbicides
* begin to become active as soon as temperatures begin to fall after the summer
  - send shoots upward toward the sky
* bloom four to six weeks after planting.
* burn more brightly and motors turn more quickly as the applied voltage is increased
  - out to frequently
* can grow quite large, and are relatively mild in flavor
  - lengthen the time a flower bed displays color
  - reproduce sexually , through seeds, or even vegetatively
* cause vomiting and nervous excitement.
* come in a variety of shapes, sizes, light intensities, power-draining properties and prices
  - wide range of color, shapes, sizes and plant heights
  - with various bases, shapes and sizes

  - prefer moist, well-drained soil
+ Lightbulb, Cautions: Light sources :: Machines :: Home appliances
  * Most light bulbs fit into a socket. If the socket is turned on, there is electricity there, even if the bulb is out, so there is danger of electric shock. Most bulbs get very hot when they are turned on, and take some time to cool off. Most light bulbs are made of glass, which means that they can break easily. Fluorescent bulbs contain a small amount of mercury, if they break, be careful to not breathe the mercury vapor. With incandescent light bulbs, the filament will eventually break, and the bulb will need to be replaced.
  * Some well-known bulbs people grow to use as food are onions and garlic. Some bulbs grown for the decorative flowers are the lily, tulip, and some irises.
