Brugmansia

Question

I live in zone 7a. I have four brugmansias (pink & yellow) running between the EAST SIDE of my house and driveway. This year makes THREE years that they have come back. They are double potted and I mulch them pretty heavy for winter. I just could consider myself lucky for having them live. Do you think that this site is what they call a micro climate? Would you do anything different? I think the roots have gone through both pot holes into the ground. How much longer do you think they can live like this?

Answer 1

Hello,

Thank you for sending us your gardening question. Lucky you! Some brugmansia plants have been reported to be hardy in zone 7b. Since you are in zone 7a, you are very close. It could be that the winters have been mild the last several years. It could be that your mulching and the area in which they are planted has done the trick. You very well might have your own microclimate! Unfortunately, due to all of the variables, it is impossible to predict how much longer your plants might live.

Here are a couple of articles you might find helpful:
