Annual how long

These plants are often referred to as tender perennials used as annuals. These can include geranium, lantana, coleus, various tropical green plants and tropical hibiscus.

If these plants are to be saved, they will need to be dug, potted and brought indoors for the winter. There are a number of annuals that may act like perennials because of the large amount of seed that is produced and dropped to the ground in the fall.

This seed remains viable over the winter and in the spring new plants emerge in and around the area where the annual was planted the previous season. Plants like cleome, snapdragon, cosmos and amaranth are examples.

Annuals are also a great option for container gardening. Annuals give maximum garden color and beauty because they bloom continuously throughout the growing season. But when it comes to planting annuals, timing is everything. Annual varieties are classified as tender annuals, half-hardy annuals, and hardy annuals and each has a very distinct planting window.

Tender annuals — Tender annuals thrive in warm soil and warm air temperatures. Half-hardy annuals — These plants should be planted once all danger of freeze and frost has passed, but they do not require that the soil is completely warmed. Hardy annuals — These plant varieties can withstand slight freezing, although not sustained freezing temperatures or drastic drops in temperature.

Annuals grown from seeds can be planted in early spring, while container plants can be planted in late spring. Additionally, hardy annuals are better suited to plant in the ground instead of in containers. This is because ground soil can better insulate plant roots. There are two ways to plant flowering annuals. You can choose to start from seeds or purchase container-planted annuals.
