Product information "Small-growing Hydrangea 'Bluebird'"

The marginal flowers of the small-growing hydrangea 'Bluebird' are different colours, which vary between light pink, whitepink and pink. The smaller, inner flowers have a strong blue colour.
Different flower colours

Contrary to other hydrangeas, the colour of the large, marginal flowers of the small-growing hydrangea 'Bluebird' does not fluctuate so strongly due to the pH value. The colour spectrum ranges from a delicate, whitepink to light pink to a strong blue; also a whitish pink can be produced. The marginal flowers, however, remain lighter in colour than the smaller, inner flowers, which have a strong blue tint. As a rule of thumb, however, the lower the pH value, the more strongly the blue of the marginal flowers is formed. These small, special flowers appear for the first time in July and then continue to bloom until October. During this time, the flowers are visited by insects. The leaves are green and often have reddish tints.
The growth of Bluebird

The small-growing hydrangea 'Bluebird' is between 1 m and 1.5 m high and has approximately the same width. The shoots are close together, producing a rich bloom.
The ideal location

As already indicated, the flower colour is dependent on the pH value of the soil; the optimum pH value is in the neutral to acidic range. For potted plants, it is not a problem to adjust the pH value so that the flowers obtain the desired colour; starting at a pH value of 4.5, the flowers will be blue. With so-called “hydrangea blue”, a special fertiliser mixture with which the hydrangea can be saturated, the substrate becomes acidic and the blue flowers appear. Of course the hydrangea can be planted from the very beginning in acid soil. When planting hydrangeas outdoors everything is a bit more difficult; one must work with the pH value that is already in the garden...
If you have an acid soil or a bog bed anyway, the blue flower colour can easily be achieved. If this is not the case, you can dig out the plant hole generously and fill it with acidic soil. Over time, however, the acidic soil will mix with the normal garden soil and the pH will slowly slide back into the neutral range. The above-mentioned “hydrangea blue” is not ideal when the hydrangea is planted outdoors, since it is quickly percolates and dilutes into the soil. Luckily, Hydrangea serrata 'Bluebird' is an ideal potted plant due to its compact growth and over the years you can experiment to get the right colour of the flowers. Please note that only soft water, i.e. rain water, should be used.
In addition to the pH value, a sunny or partially shaded location is also important. The plant survives in full shade, but markedly fewer flowers are formed. The soil should never dry out, especially during flowering. Otherwise, the hydrangea 'Bluebird' is a robust, hardy plant.
Overwintering container plants

As a potted plant, the pot should be wrapped up and sheltered outdoors. The only pruning measure that should be applied to this hydrangea is the removal of dry and old shoots.
