Difference in Seeds and Bulbs

Dahlias produce both seeds and bulbs.

Flowers can grow from either seeds or bulbs. The differences between seeds and bulbs involve their constitution and how each grows into a flower. Some types of flowers can grow from either seeds or bulbs.

Identification

A seed contains an embryonic plant. Under the right conditions, seeds germinate, or begin to grow. A bulb is a plant that stores its complete life cycle in an underground storage structure. Bulbs are usually perennials.

Time Frame

Seeds must absorb water to germinate. Pre-soaking seeds may speed up the growth process. Seeds are often planted in the spring, taking into consideration the time required for a mature plant to grow. Bulbs are usually planted in the fall. They have a period of dormancy followed by a period of growth.

Considerations

Tulips and dahlias are examples of flowers that produce both seeds and bulbs. It would take a very long time to get decent-sized plants from seeds, according to BobVila.com. Moreover, seeds for these types of flowers would most likely result in plants that don't closely resemble the parent plants.
