Questions tagged [identification]

Use this tag for questions that ask "what is this thing?" Pictures, geographic location, and descriptive titles are important. Ask only one identification request per question. When you get an answer, consider adding a further tag (for the flower, tree, beetle etc. that has been identified) so your question is cataloged correctly. If the question is about determining the cause of a plant problem (e.g. disease), the diagnosis tag is more appropriate.

When asking an identification question:

  • Make a good title:

    • Include the type of thing (weed, bug, plant, etc.) that you want to identify.
    • Include distinctive features. ("Red fuzzy vines".)
    • Include where it was found -- both where in the world, and where in a "micro" sense ("eating the lower leaves of my plant", "under a rock", "fungus growing on my tree trunk", etc).

    • Ask only one plant identification request per question. If you'd like more than one plant identified, feel free to ask additional questions.

  • Include at least one photo.

  • Repeat the descriptive features in your question.
  • Include how it relates to gardening.

When you get a satisfactory answer, consider adding a further tag so that your question is cataloged with other similar questions. If an answer makes the question relevant to another category (e.g. a vine later identified as Morning Glory), then it should be tagged as such.

How can I tell if a plant given to me is patented?

Sometimes, I receive an unlabeled plant start from a friend, and they do not know if it is patented. If I want to grow and sell a plant in question, is it okay to just take the chance, or is there a way to find patents?

I have a tree with a fairly heavy growth across its trunk and branches; I suspect that it's a form of lichen but I'm not sure. Is this something that will negatively affect the growth or health of this tree? Should I spray it down or leave it be?
