Flower, grain, herb and vegetable seeds are different types of gardening seeds, according to Garden Guides. Pumpkin, mustard and sunflower seeds are edible, and these seeds are incorporated into certain meals.
Garden seeds come in the form of annual, biennial and perennial seeds. Annual flower seeds live for a single season, and perennial flower seeds return each year. Biennial flowers last for two years, but they do not flower until the second year.
Herb seeds are usually annuals and perennials, and they can be used for dyeing, cooking and medicinal purposes. Most vegetable seeds are annuals, but there are a few that are perennials. Grains are classified as seeds, and corn and rice are considered grains because flour is usually made from them. Winter wheat is a suitable choice for home gardeners, and this type of wheat improves the soil. Other types of grain include barley, rye and oats.
Acorns, chestnuts and hazelnuts meet the botanical definition of a seed. Seeds from poppy plants are added to certain cuisines and are frequently used in Eastern European dishes. Coriander seeds are normally used in Indian and Mexican dishes. Cumin is another seed found in Mexican foods, along with foods common to the rest of the Americas. Asia and Western Europe are other common places where cumin is used. Nigella seeds are common in Mediterranean, South Asian and East Asian cuisines. Anise and fennel seeds have a licorice flavor that is popular in Mediterranean and Middle Eastern cultures.
