Black-eyed Susan vine is a beautiful green climbing vine that produces striking yellow flowers that looked like daisies. Native to the subtropical jungles of Central Africa, black-eyed Susan vines require humid and warm areas in order to thrive. If you live in warmer southern states, a black-eyed Susan Vine will be a perennial and bloom year after year. However, if you live in colder areas, the black-eyed Susan Vine will be an annual and need to be replanted every year. If you want to propagate black-eyed Susan Vine, you will have a couple of options; so, here is a how to guide on how to propagate black-eyed Susan Vine.
Step 1 - Sow from Seed
If you live in warmer, evergreen climates, you can sow black-eyed Susan seed directly into the soil where you want the vines to grow and climb. Black-eyed Susan Vine seed usually germinates best in soil temperatures that remain between 60 degrees and 70 degrees. However, if you live in a colder climate area, you'll need to begin the seeds inside, and then transfer them outdoors during late spring or early summer. If you are starting your black-eyed Susan Vine seeds inside, you should start them about six to eight weeks before you will be transplanting them.
Step 2 - Create Herbaceous Stem Cuttings
The other way to propagate your black-eyed Susan vines is to use herbaceous stem cuttings. In order to achieve this, place a stem cutting from your black-eyed Susan Vine in clean tap water and leave it there until roots begin to develop and grow. After roots begin to appear on the herbaceous stem cutting, you can then transfer the cutting to a plot to keep indoors (if the weather is still cold), or directly transplant it to the area where you want them to grow and climb.
Step 3 - Self Propagation
If you live in a warmer climate area, Black-eyed Susan vines will usually propagate on their own without any assistance at all. After Black-eyed Susan Vines bloom and flowers fade or die, seeds are usually dropped to the ground that will result in new vines being created. You can collect seeds that fall to the ground and store them in plastic bags to use at a future time. If kept dry and warm, black-eyed Susan vine seeds will usually be viable for two or three years.
Black-eyed Susan vines generally don't respond well to division or transplanting. Most of the time, attempts to divide and transplant black-eyed Susan vines will simply result in the death of the vine or unattractive and unhealthy appearance if the vine does happen to survive.
