Actually this is a possible 'bug.'
If you take a cutting in your own yard while gardening, it WILL retain metadata about the cutting. (eg, what plant).
If you take multiple cuttings remotely, it will show you the metadata while you are REMOTE.
If you travel home, you still have the stack of cuttings, but the metadata is WIPED. They are now just arbitrary cuttings to you as a viewer. In actuality they are still the plant cuttings that they were taken from however you cannot tell what they are.
If you are trying to hybridize plants with grafting, to get possible unique new plants (such as I am at this point), and you come home with 3 cuttings and have three specific cuttings which you intend to graft to 3 specific different plants it's now a sort of game of chance. If you guess wrong, you graft onto the wrong plant and start over. If you save before doing this it's not as huge a dilemma but... I figure it's worth reporting. It's a lot of hassle.
Or, you can take one cutting at a time and going back for more, but the plant states may have changed (or despawned entirely, it remains to be seen -- state does not seem to either progress or maintain consistently in remote neighborhoods while you are absent, eg, time does not 'flow' consistently across all places in the game if you are not "in" it -- which isn't a problem per se, just a problem with trying to find plants).
In my opinion I'd put it down as a minor quality of life bug (compared to the puddles in my yard :P )
