The standard sample is young growing leaves that are dried using our standard protocol. We provide all the necessary collection material. Samples other than standard dried leaves require special handling and carry a $50 per sample surcharge. Collection instructions for non-standard sample types are provided case-by-case.

The service does not distinguish between bud-sports (aka. somatic mutations, clones) within a given variety.
