One plant that add so much work on my garden is a wild plant called Urtica Dioica. I have to keep on removing them since they grow rapidly and wildly. Wikipedia mention it as common nettle, burn nettle, stinging nettle or nettle leaf, or just a nettle or stinger. It is a herbaceous perennial flowering plant in the family Urticaceae. After touching the plant, the hair that grows penetrate my skin and stinging sensation immediately appears. The fine hairs on the leaves and stems contain irritating chemicals. Despite of its benefit that can be used to treat various ailments when properly prepared, I still do not want to have it grow in my garden.
However my regular interactions with this plant has brought me to an awareness of its growing behavior. I have some other flowers that I love to have and grow in my garden, wishbone flowers. The leaves are similar to the burn nettle. The nettle plant always grow nearby the wishbone plant. If you don't interact with them on the daily basis, you will hardly notice the difference between them. Another behavior that I observe, the nettle plant tend to hide among the rocks and make it hard for me to notice and remove them.
I wonder if they both belong to the same family or they have similar growing habit that make them grow on similar spots. I wonder if I would like to spend some time on doing a small research on the benefit of the burn nettle.
