Thunbergia Seeds Black Eyed Susan Trailing Vines
Thunbergia Seeds Black Eyed Susan Trailing Vines
Thunbergia Seeds, also known as Black Eyed Susan, grow into large trailing vines with bright yellow flowers that feature dark centers. No green thumb required. These seeds can be grown year round and kept outdoors in more moderate climates or indoors. They like to climb, so a trellis is very helpful. For sowing, use a 12 Cavity Greenhouse or Planter with Humidity Dome. These seeds are designated for the 2026 growing season.
Seed germination takes 7-21 days with a depth of 1/4 to 1/2 inch. Space 1-3 seeds per planter or 8-12 inches apart, and use a 6- to 12-inch planter, box, or garden bed. Time to maturity is 56-63 days. Seed prep options include pre-soak, scarification, stratification, or none. Germination methods include greenhouse, paper towel method, or direct sow, and temperatures should stay above 50F. Perennial vines with blooms varying from white to yellow and orange; plants reach 5-8 feet long with 1- to 2-inch blooms.

Let customers speak for us
Good solution. The little flies have disappeared. We were sure to mist/moisten the surface of each plant once a day for 4 or 5 days, after the initial application of the nematodes, to keep the little guys mobile and able to get to any remaining eggs. So, go for it!
Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!
The organic garden soil is doing very well in my garden bed. The company was professional, nice, and accommodating to my needs. They provide many types of things for your landscaping at a reasonable price.
Product was delivered promptly and the quality of the product was very good, as hoped for. I was thrilled to receive the product so quickly! Thank you!
Product is great. Didn't care for having to pay am extra $17 tariff to UPS to get it delivered, but I guess that's not your doing. Thank you Mr. President.
My new babay arrived safely and only lost two little leaves so far. The first one I ordered from different shop arrived with two leaves attached that fell off within ten minutes of unboxing and 22 leaves that had came off during shipping. So glad she arrived looking as beautiful as i was hoping. Also had a surprise red arrow syngonium cutting that’s beautiful. Also customer service was amazing. Will definitely order from them again. Hoghly recommend this shop.
Great flag and it works well on our hangar ceiling. A little worried it wouldn't arrive in time for our event but it did.
Enjoyed putting them together
I think I’m in love! This beauty came delicately packaged. Seemed to have no stress at all from shipping. I live in Miami, I was worried about shipping all the way from California. To my surprise she arrived well taken care of already. I can tell this grower takes pride in caring for these babies. Shipping was fast. I just ordered again same day!
Great service and great product. Delivery was quick. Good communication.
lovely olive jar, attractive to keep on display. And useful too.
Fast delivery . Product exactly matches description. Easy to contact with same day replies. We will use them again.
Great job from growing to shipping
Quality was excellent. Perfect for my Dad’s grave site, honoring a proud Marine.
Appreciate the extra effort to get the product to me when needed. The delivery was made with speed and consideration, very much appreciated
