Annual Plants in USDA Zone 6

Impatiens

• Impatiens are available in many different varieties. They range in size from 8 to 24 inches tall and form mounds as they grow. Color selections are almost endless and include white, red, salmon, pink and purple. Striped varieties are also available. Impatiens can be used as bedding or border plants and also do very well in containers. They grow best in partially shaded areas and nutrient-rich soil. Impatiens should be watered regularly, especially during the heat of summer.

Zinnias

• Zinnias are among the most versatile and carefree annuals that can be added to the garden. They are available in many colors, from bright pink and yellow to rich red and orange. They grow 1 to 3 feet tall, depending upon the variety, and do well in beds or containers. Zinnias also make excellent cut flowers. They prefer full sun and will thrive in almost any soil as long as it doesn't remain excessively moist.

Cosmos

• Cosmos are tall, lanky plants that produce large, multi-petaled leaves in a wide variety of colors, including scarlet, orange, white, pink and yellow. They reach heights of 2 to 4 feet and are notoriously easy to grow. Sow the seeds in a sunny spot in your garden after all danger of frost has passed. They do best in poor soil, making them the perfect choice for areas of the yard where other flowers struggle to grow.

Scarlet Sage

• Scarlet sage, also called salvia or Texas sage, has 1- to 2-inch, pointed leaves and grows 2 to 3 feet tall. In early summer tubular, scarlet flowers begin to line the stems and continue to appear until frost. Scarlet sage does best in full sun and grows even in poor soils. It is fairly drought tolerant, but regular watering will ensure prolonged, attractive blooms. Scarlet sage is self-seeding and will return year after year if the planting site is left undisturbed.
