Sweet Annie is an herb native to parts of Europe, Africa and Asia, but is now grown throughout much of the United States. This herb is often grown for aesthetic reasons, and can easily reach heights of more than 6 feet in a single growing season. The plant also leaves a sweet, comforting smell in the air that can be smelled from several feet away. Like most other herbs, sweet Annie is generally easy to care for, but starting it from seed can be troublesome.
Fill a pot with potting soil about two months before the last predicted frost. The pot should be at least 4 inches in diameter to provide ample room for growth. If you want multiple plants, prepare a pot for each plant.
Lay two or three seeds in the center of the pot and lightly sprinkle soil over them. It's best to plant a couple extra to ensure you get at least one seed that germinates. Water the soil so it is thoroughly wet, but not soggy.
Put the pot near a sunny window that stays between 60 and 70 degrees F.
Check the soil every other day to ensure it stays wet. Water it again as soon as it begins to dry out.
Harden the plant once it reaches a height of 2 inches, which should be around the same time as the last frost. Put the plant outside in a protected area for an hour on the first day and increase the time by 30 minutes each day afterward.
Thin the plants if more than one grows in a single pot. Simply pull out the plants that appear to be weakest.
Transplant the plant outdoors in a sunny spot once the ground thaws out. Dig a hole about the same size as the pot with a garden shovel, then remove the contents of the pot and place it in a hole. The soil should remain intact when you pull it out of the pot.
Space any additional plants at least 3 feet apart if growing more than one.
Keep the soil moist throughout the entire growth cycle. The plants will grow rapidly and may reach heights of more than 6 feet by the end of summer.
