Sunday Activity: DIY Flower Dyeing

Buying flowers for yourself is one of the best ways to start your weekend. I always feel exceptionally giddy when I pick out a bouquet for myself and march home with my precious cargo. Every time I pass it, I admire the simplicity of it and it genuinely makes me feel good. This may seem like overly passionate talk, but if we can’t appreciate flowers, why are we here?? With an affinity for flowers on our minds, we have a fun little activity for you. It’s very simple—heck, you might have even done this in elementary school to learn about plant biology, but we’re bringing it back because it’s a great thing to do on a lazy Sunday. Introducing: flower dyeing. All you do is add a few drops (20 should do it) of food colouring to your flower water and cut the stems (using a knife) on a 45-degree angle. Then you get to watch your bouquet magically change colour. Of course, it’s not magic—the science behind it quite simple:

“Water moves through the plant by means of capillary action. Specifically, the water is pulled through the stem and then makes its way up to the flower. After two hours of being in the dyed water, some flowers should have clearly showed dyed spots near the edges of their petals. The water that has been pulled up undergoes a process called transpiration, which is when the water from leaves and flower petals evaporates. However, the dye it brought along doesn’t evaporate, and stays around to color the flower. The loss of water generates low water pressure in the leaves and petals, causing more coloured water to be pulled through the stem. By 24 hours, the flowers should have gained an overall dyed hue, which darkened a little over time. The stems should have also become slightly dyed in places, particularly where the leaves branch off.” – The Scientific American
