I vaguely remember borrowing a seed pod off the neighbor’s trumpet vine in the fall of 2018, and last year I had a bunch of Campsis seedlings vigorously growing and starting to vine.
This second year, many of them continued to grow and contemplate vining. I didn’t give them anything to climb up yet–maybe next year.
What I like about these plants is that the foliage has interest in spring with reddish new growth, and interesting fall color, as well.
I may have the identify of these incorrect–the leaves don’t look exactly like the Campsis down the street. My future plans are to keep them growing in pots and tonsai a few of them in the coming years.
