How was Diervilla Honey Surprise created?

William de Bruijn of Boomkwekerij William de Bruijn discovered a striking mutant through multicoloured leaves in Diervilla splendens.

What immediately struck him when he found the mutant were the different colours in the leaf. After taking cuttings and going through the process of propagation, it appeared that the foliage also differed in colour throughout the year, from silver in the spring, to red and yellow in summer and autumn.

William does not remember exactly when he found this mutant, but it took a few years before the nursery had a reasonable number of plants ready for sale. Once more plants were grown at the nursery, Honey Surprise stood out for visiting customers due to its leaf colour.

What is a mutation?

A mutation is a natural occurrence that can alter the appearance of the plant’s foliage, flowers, fruit or stems. Chimaeras, sports and breaks are some examples of common plant mutations.


Variegated monstera
Examples of popular mutations

Variegated monstera are an example of chimaeras in plants. This causes some of the plant’s leaves to appear white due to a lack of chlorophyll. This chlorophyll deficiency also means that the plant grows slower and takes longer to propagate, which is why you may have seen some variegated monstera selling for thousands of pounds!


Lavandula x allardii ‘Meerlo’

Lavender ‘Meerlo’ is another example of a variegation mutation. Unlike variegated monstera, this lavender produces uniform variegations across its foliage, with each leaf featuring creamy edges. Find out more about this plant here.

Why do mutations occur?

Many mutations are random and a luck of the draw, but sometimes mutations can occur as a result of the conditions of the plant’s environment; for example, if it is exposed to very cold weather or damage from insects.

Are mutations permanent?

Usually, plants will revert back to their original form in the year following the mutation. However, as with Honey Surprise, mutations can be duplicated through propagation for a permanent effect.
