Castle in France - Chambord Castle
Chambord Castle is a masterpiece of Renaisance architecture, surpassing all other famous French castle until the construction of Versailles a century later. Built in 1519 and employed 1,800 workers. The original design is attributed to the Italian architect Domenico da Cortona, but Leonardo da Vinci was also thought to have inspired much of the architecture.
The secret behind the Rainbow Roses
I know, it seems a joke, the Rainbow Rose you see is real, but its coloring is man-made. While it is bizarre and unnatural, at the same time is incredibly beautiful.
Staining roses with dyes is a common practice to obtain flower colors that are not available in nature. However Rainbow Roses are most unusual because the petals of the same flower display various colors.
The technique for producing Rainbow Roses was developed by Peter van de Werken from River Roses®, a flower company located in Holland. It is an elegant application of basic knowledge of plant anatomy.
The different colors between petals are a consequence of phyllotaxy (the form by which leaves -or nodes in general- are arranged on the stem). In the case of roses the leaves are arranged in a five-ranked spiral, which means that when an imaginary line connects the various leaves a spiral is formed so that after two full rotations leaf number 6 is on the same vertical plan as leaf number 1. Petals are modified leaves and follow the same arrangement.
To obtain a flower with petals stained in different colors the stem is vertically cut into four equal parts and each quarter dipped in a different dye. The dye moves upwards through the xylem to the petals, which get a different color depending on their position in the spiral.
The technique is actually quite simple and can easily make at home. The only thing that could influence your results is the variety of rose you employ, since not all cultivar absorb all the different colorants perfectly. Here you can see a short video showing the technique (although the results are not the so fine as in the photo).
