== Life Cycle == | == Life Cycle == | ||
The red raspberry is usually biennial, and each shoot passes through a easily interpreted stage during its two year lifespan. Vegetative shoots develop from the parent's roots or stems or they would develop as seedlings during the first year. Floricanes are produced the second year and they leaf out early and and grow rapidly. In the late summer, it produces fruit and after this, the cane and the leaves of of the old floricanes die.

==='''Flowering:'''=== | |||
In the American red raspberry, flower buds are initiated by temperature, genetics, and geographic location. Flowering is also influenced by the age of the plant and the date that the vegetative growth is terminated. Flower buds are triggered by lower temperatures, and short days. This usually occurs in the late summer or autumn. The more exact trigger of the flower buds is at an exposure to fifty-five degrees Fahrenheit and nine hours of daylight or fifty degrees Fahrenheit and sixteen hours of daylight. In spite of this, evidence suggests that higher spring temperatures promote sooner and faster flowering. [http://www.fs.fed.us/database/feis/plants/shrub/rubida/all.html] | |||
