The pack contains 12 plants actual height 20 – 23mm, 3 plants each of 4 colours.
Shrub hydrangeas can range in size from 0.8m to 7m in height with a spread of 0.9m to 2.5m. This means these miniature hydrangeas would suit most models. However, the bloom size means that 1:100 is the smallest for which they are really suitable.
Flower colour in the real plant is affected by the acidity of the soil: acid soil makes blue or mauve flowers with pink being the result of growing in alkaline soil. Therefore, if you are creating a realistic scenario, do not plant the different colours together. White blooms are variety-specific so can be planted anywhere. The pink and white variants could also pass as rose bushes.
