Is there a different bracha for seeds than for fruit? What about seeds from different sources: a seed from a plant vs a seed from a tree vs a seed from a grain?
Seeds from plants are haadama, seeds (better known as nuts) from trees are haetz.
Peanuts are haadama.
If the seed of a particular fruit is not normally eaten, like seeds of apples and oranges then if it tastes sweet it would get haadama (because it’s secondary to the fruit, and is not grown for that purpose) and if not then it would get no bracha.
This is the general concept but there are some rules so if you have a specific product in mind please let us know so we can give you a definitive answer.
