Plants that don’t produce seeds are usually either rare mutations or intentionally crossed in a way that makes them infertile. Losing their ability to produce seeds usually dooms them to die out without humans caring for them, so their wild types should have seeds.

edit: For example, [this is how daffodil seeds look like](https://upload.wikimedia.org/wikipedia/commons/thumb/0/0f/Narcissus_pseudonarcissus_MHNT.BOT.2009.13.31.jpg/1920px-Narcissus_pseudonarcissus_MHNT.BOT.2009.13.31.jpg)

There are two ways for these plants to reproduce themselves, they can make bulbs, which are clones of themselves, or they can make seeds, which are a mix of their characteristics and the other parent’s characteristics. In a stable environment where you are doing well it’s a great strategy to clone yourself. Why fix what isn’t broken? But if the environment changes or you try to grow in a different environment then varying the characteristics of your offspring gives a chance that you’ll hit on a great combo for those new/different conditions.

Say you are great at growing in wet soil and at growing in low light conditions, you are going to clone yourself and dominate your little wet patch by the creek under the trees. But the wet patch extends out from beneath the trees and you just can’t cope with the heat of the full sun. You’re going to want to combine your wet tolerance with the heat tolerance of a plant which can grow in full sun in order for your kids to be able to dominate that full sun part of the wet spot. And, as an unexpected bonus, when a storm comes and knocks down the tree you were growing under and you and your shade loving clones die, your genes will live on in your sun adapted children.

Once in a while you’ll get a fruit off of a regular tulip or iris plant. It looks like a big green pod. Those have seeds inside.
