Annuals




Annuals complete their life cycle in one growing season. They transform the garden into colorful vistas in the spring and fall of each year. Shurbs and Perennials are the workhorse of our gardens and create structure to the landscape. Annuals add the pop and glamour to the garden.

Most annual flowers are offered as bedding plants in 2 inch cell packs or in 3-4 inch pots. Annuals are transplanted or direct seeded each year.

In the spring, set plants out into the garden after all chance of frost in your area. Some plants such as impatients dont begin to take root until the soil has warmed up.

Annual flowers differ in their tolerance to cold weather and frost. Hardy annuals are the most cold tolerant. They will survive light frost and moderate freezing weather without being killed. In most cases, hardy annuals can be planted in the fall or in the spring before the last frost date.

Most hardy annuals are not heat tolerant. They usually decline and die with the onset of hot summer temperatures.Half-hardy annuals will tolerate periods of cold, damp weather but are damaged by frost. Most half-hardy annuals can be seeded outdoors in early spring since they do not require high soil temperatures to germinate.

They are . Many half-hardy annuals decline in the midsummer heat but may rebloom in late summer or fall.Most tender annuals are native to tropical regions of the world and are sensitive to cold soil temperatures and are easily damaged by frost. Wait two to three weeks after the last spring frost to plant (seeds or transplant) outdoors.

Most seeds will not germinate when soil temperatures are below 60°F. Tender annuals include ageratum, balsam, begonia, celosia, coleus, globe amaranth, impatiens, marigold, morning glory, nasturtium, nicotiana, petunia, scarlet sage, verbena, vinca, and zinnia.

Annuals are sometimes categorized as cool- or warm-season. Cool-season annuals, such as geranium, petunia, and snapdragon, grow best when the temperatures are in the 70s and 80s during the day. Best flower production is in the spring and fall; flower production declines in the middle of a hot summer. Warm-season annuals, such as blue daze, four-o'clocks, vinca, and pentas, perform well when the daytime temperatures are in the 80s and 90s and the night time temperatures are in the 60s and 70s.
