The plant will change Tiers (when originally Tier 1-3 ) whether before or after pollination. That makes no difference. My apologies if I have confused you.

If the flower or foliage was a Tier 3 and changed then the plant will almost always decrease in value.

The reverse is true, if a flower or foliage changes to a Tier 3, the value of the plant will increase.

The exceptions are non-Tier 3/Tier 3 Magic Plants and one glitch in the pricing table.

yeah i havebought a 4petal maple seed from the SS before, but i had already discovered it.

I’ve purchased aureus scanders, fourpetal maple, mela rare, and oak seed.

I bought the fourpetal maple seed for $50 but had alreay discovered it.

I had my 6th magic plant straight purchased seed Aureus Scandens.
