According to Chinese traditions, the significance of lucky bamboo is tied to how many stalks you have. There are different meanings associated with various lucky bamboo arrangements. For example:

Two stalks represent love.
Three stalks represent Fu (happiness), Lu (wealth), and Soh (long life).
Five stalks represent balance, peace, harmony, and power in all areas of your life.
Six stalks represent good luck and wealth.
Seven stalks represent good health.
Eight stalks represent growth.
Nine stalks represent great luck.
Ten stalks represent perfection.
Twenty-one stalks represent a powerful blessing.
You’ll rarely find a traditional lucky bamboo arrangement with four stalks. In Chinese culture, the word for “four” is close to the word for “death,” so a gift of four bamboo stalks would be considered very rude as if you had wished death on the recipient.
