how long do kalanchoe flowers last?
Kalanchoe flowers typically last 6 to 8 weeks in bloom, and with proper care the flowering period can extend even longer. The plant is prized for being one of the longest-blooming houseplants available, making it excellent value as a gift or home decoration.
what does kalanchoe symbolize?
Kalanchoe symbolizes enduring affection, happiness, and new beginnings. In Chinese culture it is known as the longevity flower and is given as a Lunar New Year gift to bring wealth and good fortune. Its winter blooming also makes it a symbol of hope and warmth during the coldest months.
can kalanchoe grow outdoors?
