Perennial flower.
Full sun, partial sun.
Cold stratification to sow your seeds, cover seeds about 1/8 inch of soil.
Grows 6-8 feet tall. Every year it grows taller until it reaches to its height of maturity.
Fertilize every 2-3 weeks. I like to do once a week.
Prefer moist soil.
Some varieties will bloom throughout the entire summer if the plants are cut back regularly. So cut back flowers that are already done blooming.
Sold in each color, 4 grams, $7.
Picture #1 shows closes to the 3 colours I have with the arrow pointing to the color. I have mostly color dark blue with a hint of purple.
