What is hybred vegetable seed?
A seed that is classified as being a hybrid is one that comes from a plant that was produced by pollinating multiple plants. This combination makes a better plant; however the seeds from the hybrid plant will not reproduce themselves.
Botanically speaking, yes; only fruits have seeds. Vegetables are seedless. Perhaps a little clarification is needed here. Fruit and vegetable plants all have seeds. The vegetable as we use it in the kitchen is not the part of the plant that produces the seed,except with peas and beans. With fruit the seed is contained within the fruit i.e. the seed pod.
