These plants grow 18 inches to 72 inches in height. They bloom from mid to late summer into fall. If you have shorter varieties, then plant them 18 inches apart. The taller varieties need to be planted 44 inches apart.
Black Eyed Susan plants can be propagated through seeds. You can sow the seeds directly into the flower garden soil in spring. You will be able to propagate the plant after two to three years by separation or division. You need to dig up a clump and separate it, or divide it into three or flour smaller clumps. Replant them and water well.
When transplanting the plants, remember that once they bloom in fall, you can divide and transplant them in spring. If you see them bloom in spring, then you should be transplanting these plants in fall. These plants can resist the stress of being relocated. To cause the least amount of stress, transplant the plants during their dormant state in early spring or fall. You should not worry if the flowers do not bloom the first year after transplanting. They will begin to bloom in the coming years.
The following instructions will help you grow these plants in your garden.
- You can find seeds in the local nursery. It is very easy to grow and maintain these plants.
- You should sow the seeds indoors for about 6 to 8 weeks before the last frost date. In mid-winter, you can plant the seeds directly in the garden soil in early spring. (You can plant the established seedlings in the garden soil after the last frost date.)
- These plants, like the Thunbergia Alata, are vines. You would, thus, need to provide them with support. You can install trellis or arbor to help them rise skyward as these plants climb by twining.
- You should water the plant with sufficient water. After planting, if you desire, fertilize the soil every 4 to 6 weeks.
- You should pull out the plant after the first frost.
