Please provide at least an insight in what you did, how your model performed and some decent samples which you trained with!

Did you cut out the positives or annotated them? How about test samples?

While using the CascadeClassifier::detectMultiScale, you can play around with the function arguments, particularly scale and size of the object detected. This should weed out small objects such as the leaf stem. Take a look here

PS: The third image from the bottom right in your training set suspiciously resembles the falsely detected leaf stem in the sample test image you've provided, hence the misclassification. Adjusting the minSize argument in detectMultiscale might help fix this issue.
