The Q&A Archives: trumpet seed pod

Question: I have just taken a seed pod from a trumpet tree the plants from the tree looked almost orange in color. Do I need to take the seeds from the pod or can I keep them in? Also when do I plant them and how? Can I just plant them now and will they grow?

Answer: This plant (Campsis radicans) often seeds itself with an almost aggressive tendency, so the seeds are fairly easy to grow. I hope the seeds you collected are fully ripe -- normally they rattle in the pod and the pod is dry and splitting open when they are fully ripe. You could keep them dry and at a cool room temperature until later winter/early spring, then chill them in the refrigerator for about two months (place in damp vermiculite in a plastic bag) then place them on some old rotted mulch or prepared seedbed in the garden where you would like to have a vine. Do not cover the seed as it needs light to germinate, the spring rains and naturally damp soil should do the job. Otherwise you can set the seedpod in the garden where you would like the vine and allow the seeds to cold stratify naturally. You can also transplant the seedlings while they are small. If you want a plant that matches the parent in flower color, it is more reliable to take tip cuttings during the summer. Good luck!
