No, coffee grounds do not keep hydrangeas blue on their own.Specifically, the blue blooms on the hydrangea are the result of the plant being able to take aluminum from the soil into the roots. Aluminum has to be in soluble form for plant root intake. A soil that is too dry impedes adequate aluminum intake and therefore proper blue blossoming. Coffee grounds work to retain moisture in soil.
Yes. Hydrangea contains hydrangin, which is a cyanogenic glycoside: a chemical compound that, when activated, releases hydrogen cyanide.Since the taste of the plant is unpleasant, a child is unlikely to consume a deadly amount; however, even minor toxicity may cause abdominal pain, diarrhea, and vomiting. All in all, it's wise to keep hydrangea away from young children who are still exploring by putting things in their mouths.
To preserve hydrangea flowers, cut the stems at an angle, place them in water immediately, and keep them in a cool location away from direct sunlight. Change the water every few days and mist the flowers with water to maintain their freshness.
