Interestingly, certain varieties display colors depending on the pH of the soil, such as pink in alkaline, and purple or blue in acidic soil, while others have fixed colors.

While most hydrangeas commonly reach around 2 to 9 meters in height, others can reach up to 15 meters, especially the H. petiolaris or the climbing hydrangea. In north temperate regions, these flowers bloom in the early spring to late fall, but they’re also grown in tropical and subtropical areas.

Note: These lovely blooms are poisonous when ingested. In fact, the flowers, buds, and leaves of the plant contain glycoside amygdalin, which can be broken down to produce cyanide. As you probably know, cyanide is a deadly poison. Also, you shouldn’t attempt to smoke dried hydrangeas, as it’ll likely produce a sublethal dose of cyanide gas.
