Hydrangeas display different colors primarily due to the pH level of the soil in which they grow. In acidic soils (pH below 6), hydrangeas typically produce blue blooms, while alkaline soils (pH above 7) result in pink flowers. Additionally, the presence of aluminum ions in the soil can influence the coloration, as they are more available in acidic conditions, enhancing the blue hue. Certain varieties may also have genetic traits that affect their color response to soil conditions.
No. They are flowers that grow from seeds.
In gardening
No, hydrangeas do not grow from bulbs. They grow from woody stems and produce flowers on new wood each year. They can be propagated from cuttings or by layering.
Yes, hydrangeas can grow in sandy soil as long as it is well-draining and the plant is provided with adequate water and nutrients.
It is very easy to grow hydrangeas in Queensland. They virtually grow wherever they are planted. Out west, they will need more water, and it is still important to keep them watered well in coastal areas during dry seasons. A fact sheet on growing hydrangeas in Australian conditions can be found at the related link below.
The seeds you plant will grow into different colours. You cannot choose the colour seed that'll grow, it's random.

The seeds you plant will automatically grow into different colours at random. You cannot buy the seeds in individual colours.
You can change the color of hydrangeas by adding water-soluble dye to their water. The dye will be absorbed by the flowers, resulting in a different color.
Sulfur helps hydrangeas grow well and develop vibrant colors by lowering the pH of the soil, making it more acidic. This acidic environment allows hydrangeas to absorb essential nutrients like iron and aluminum, which are needed for healthy growth and colorful blooms.
Neon tubes are lined with phosphors, which are available in many colors.
When you have planted your seeds you wait for them to grow, when you come back later you will have your plants and they come in lots of different colours and you have no choice what colour you get.
