In order to Identify a plant correctly one must know several key details about the plant.

• Describe its general structure. Is it a
  grass
  sedge
  rush
  fern
  flower
  vine
  shrub
  tree?
  
  
• Where is the plant located?
  Where do you live?
  
  
• In what type of habitat, if known?
  Forest
  Desert
  Aquatic
  Urban
  Suburban
  your backyard?
  
  
• The color of its flower, if it has any flowers?
  
  
• Describe a leaf, what is the shape of the leaf?
  Are the leaves opposite each other or do they alternate along the stalk?
  
  
• What type of root system does it have, If Known?
  
  
• Add anything else you can think of.

A picture is very helpful, but make sure it is:

• In focus
• Has the proper exposure
• Shows details of the leaves, flowers,
• Anything unusual about the plant.

Hi! Just Dahlia

My thought exactly...

I've noticed in the last few days there has been an increase in members asking for plant identification, but there are no guidelines to help in identifying their plant. I'll write to cb...

Wonderful wonderful.. sometimes I find soil type can be helpful in identifying a plant type too as some only grow in certain types of soil

I wanted to start this thread so that Members, and guests would have a central depository to learn, and ask their questions 'bout that "mysterious plant over there in the corner of their property".

K

I do think it will help.. I know there have been times when I've wondered about plants... like that 'shroom.. you showed a pic of.. I found one almost idenitcle to it at home here.. have the pic on my phone if you want me to post it to see how close they are to each other

Here you go...

More links to help in your search. If you run into difficulty don't hesitate to post a question here.
