Plant information Service routinely asks visitors to submit plant samples for accurate diagnoses and identifications. However, we willno longer allow samples of boxwood (Buxus), pachysandra (Pachysandra), and sweet box (Sarcococca) to be brought to the Garden, in order to prevent the spread of boxwood blight, a devastating fungal disease that affects these plants. Please feel free to contact us with questions about boxwood blight without bringing plant samples to the Garden. You can also click here for more information about boxwood blight.
Please be sure to read our guidelines for specimen collection and submission if you will be bringing in a sample for diagnosis. If you will be sending images through the online forms above, please send files in one of the requested formats.
Remember! Our diagnosis is only as good as your sample. Please follow our guidelines for collecting and submitting samples in order for us to provide you with accurate answers to your questions.
