Groco Trumpet or Hummingbird Vine Seeds

Yes, because these are vigorous climbers, they need a sturdy support system like a trellis, arbor, or heavy-duty fence. Avoid using thin netting or flimsy stakes, as the mature vines can become quite heavy and woody.

These vines perform best in full sun, meaning at least six to eight hours of direct sunlight daily. While they can tolerate partial shade, you will see significantly fewer blooms and slower growth if they aren't getting enough light.

These are perennial vines, meaning they are designed to return year after year from the same root system. Once established, they will go dormant in the winter and sprout new growth each spring.

Trumpet vines are known for their vigorous growth habit, but they typically take a season or two to establish their root systems before they really take off. Once established, you can expect rapid vertical growth during the warmer months.

While they are excellent for attracting hummingbirds and pollinators, they are aggressive climbers. It is best to keep them away from siding, gutters, or roof shingles, as the aerial rootlets can grip and potentially damage wood or masonry surfaces.
