I have planted silver trumpet vines in the past and seem to me they drop silver trumpet vine seeds, now all you get is trumpet vine seeds. I am thinking this is not worth the planting since you can not carry on with future seeds. Plus from my silver trumpet vines I have seen no Amber regent drops this is sad. With the seed drop as it is and the regent drop as it is I guess I will not plant silver trumpet vines in the future but move on to another plant that may promise Amber, since all you get from the planting is a promise, time spent and nothing in return to use. Seeds or regents. Makes crafting that much harder and reason to think of quitting.
Silver Trumpet Vines don't drop amber. The only plants that drop amber are King Parsley, White Tiger Lily, Deadly Ninja Fig, Red Bell Pepper, and Red Huckleberries.
