I've been noticing lately, as I'm shopping for plants (caladiums most recently), that some are classified into grades (#1, #2, etc.). What does this mean exactly and how are they seperated into different grades? Thanks moderator's note: added a more descriptive title to topic
I'm pretty sure the grades refer to the size, age and quality of the bulbs. The #1's are larger and top quality, with size/quality going down has the number gets higher.
