WILL THEY RESEED.


Question
I PLANTED THE NEW SUNNY LEMON STAR CLIMBING BLACK EYED SUSAN . I WAS WONDERING IF THEY WILL REGROW THE NEXT YEAR .  THANK YOU JOYCE  

Answer
The climbing 'black eyed susan' vine (Latin Name: Thunbergia Alata) is an annual in gardening zones 2-9 (e.g. in most of North America). In the very southern portion of southern florida, south california and nevada the vine may grow year round but elsewhere the roots die in winter.

The specific variety you have is a hybrid which means that they seldom grow very well from harvested seeds.

best option is to replant every year.

If you have a cool, but frost free room, you can dig up your own plant before first frost in fall, cut it back to almost ground level, and bring in a portion of the root ball. One option is just to leave it in a dark, cool (45-55 F) basement vetting it just barely on occation, or you can put it under grow light. Then cut it back in late spring and plant outdoors after last chance of frost.
