Perennial flower.
Full sun, partial sun.
Cold stratification to sow your seeds, or sow your seeds in the Fall so your seeds can harden over the cold winter to germinate. 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, $8.
See picture #1 of the 3 colours I have. I have mostly color blue with a hint of purple which is the color on the left.
