Gardenia is the Gym Leader of Eterna City. You can find her if you go into the gym, find your way through the maze and battle the other trainers. At the end of the maze, you will find Gardenia and are able to battle her
really gardinia has grass type Pokemon so fire typ moves or ground types should do the job.
The second gym is in Eterna City. The gym leader is Gardenia, who specializes in Grass-type Pokemon.
You will have to trade for the Ice Beam TM if you want it to defeat Gardenia because the Ice Beam TM cannot be found until you get to Route 216 and you will need to beat Gardenia before you can continue on.
She comes because you have got a grass related item and she likes grass types she wants to come and see it.

If I'm correct, the Gracidea flower cannot be obtained in Pokemon Diamond. Sorry! (Note: The Gracidea can be obtained in Pokemon Platinum.)
A gardenia is a type of flower. Mom grew a huge gardenia and won a prize at the flower show.
"Gardenia" is the name of a flower. It is small, white, and has a waxy texture. The flower smells very sweet. It grows on a bush with dark green, shiny leaves.
The gardenia, actually not a flower but a flowering shrub from southeast China, is not the state flower for any U.S. States or Commonwealths. However, not every state flower is a flower - some are trees. The Tahitian gardenia is the national "flower" of Tahiti. ~ Madeline, NYC and NJ dog trainer

I don't think you can battle Gardenia in Pokemon HeartGold.
Even though it was Spring, the gardenia failed to flower on the plant.
