The idea is that the plants look less like cannabis with 3-finger leaves. The bright colored buds also help make them look less like cannabis. One of the most popular variations of the Ducksfoot (Ducksfeet?) strains is called Frisian Duck by Dutch Passion. This strain thrives outdoors and grows with the traditional stealthy leaves. This strain also often makes bright, beautiful purple buds (with cold enough temperatures) that have a fresh scent that is sometimes even a little fruity. Frisian Duck plants react well to growing in a living soil that’s been composted and amended with slow-release organic ingredients. This is a Frisian Duck plant in the vegetative stage. This Frisian Duck plant was grown outdoors in a greenhouse.
More than half of Frisian Duck plants grow bright purple buds! Frisian Duck is based on the famous Frisian Dew strain which also produces purple buds and has been bred for generations specifically for growing outdoors. The Frisian genes thrive under sunlight, and buds are resistant to bugs and mold! This Frisian Duck plant is just about ready to harvest! However, even with stealthy strains, be aware that they still smell like cannabis in the budding stage! Sometimes you’ll see purple leaves because of a nutrient deficiency, but oftentimes purple leaves are actually caused by natural plant processes! There are many species of plants that make purple leaves. The leaves appear purple due to high levels of a purple pigment called anthocyanin . Anthocyanin may act as a sunscreen for plant leaves because it protects against damage caused by UV-B rays. Anthocyanin is also known to help protect against cold or heat stress on the cellular level. It’s not just cannabis plants that grow purple leaves. Here’s an example of a False Shamrock plant, which has glorious purple leaves from top to bottom! With some cannabis strains, the leaves may turn purple while the buds stay green. Just like with buds, the leaves are more likely to turn color when the plants are getting cool night temperatures in the late flowering stage. The leaves most likely to be affected are the top leaves and other leaves getting direct light. With this purpling, the leaves in the shade of the plant usually stay green. For some strains, the leaves may turn purple while the buds stay green. The leaves of this plant turned purple overnight after that plant was exposed to chilly night temperatures. The leaves exposed to direct light are most likely to turn purple, while leaves in the shade often stay green. In this case, all the leaves that are exposed to the light have turned purple, including the sugar leaves. However, once the leaves are trimmed off, the buds will be mostly green. Buds may still be purple-tinted from leaves that weren’t completely trimmed off.
If there’s a lot of purple leaves, there may be a lot of color left even after trimming. The top leaves of this Super Purple Haze plant have turned a vibrant purple. Here are the buds from that Super Purple Haze plant drying – you can see that the parts of the buds that were exposed to the light have strong hints of purple. A closer look at those buds so you can better see how much bud is purple and how much is green after being trimmed and dried (click for a closeup!) This cannabis plant has grown vibrant red and purple leaves. This outdoor cannabis plant has turned purple everywhere it received direct sunlight.
Cannabis sometimes has neat mutations, like this two-tone plant where only half the leaves turned purple!
