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.
