Q. Different Leaves

My daughter and I both sent for hummingbird plants that we saw advertised on the internet. It was a special of some kind that if you bought 2 you got 2 free. All plants arrived in good shape and I put them all in water. They have now sprouted leaves but none of them look like the hummingbird plants we see planted around here. Most have foliage that look wispy and fern like. Our plants have leaves that look a lot like Rose of Sharon. We now have all these plants and are not sure what to do with them. I have been reading anything I can find on the internet, but I am still not sure of what plants we really have. How many different kinds are there? I have not been able to find out. Thanks for your help. Patricia

Seems like a good question to ask the seller. The only 2 vining plants that are commonly called hummingbird vine is the one you describe, and Campsis or "trumpet creeper". Campsis, unfortunately, doesn't have leaves like alcea. Hope you can find out.

Q. Campsis cuttings

Hi, I have Campsis flourishing in my garden and would like to propagate plant cuttings, should I take softwood or hardwood cuttings your instructions do not say which cutting is preferable.

It is always faster to take softwood cuttings, but in this case it won't matter. This plant is highly invasive in most areas. They will root with no hormone most of the time, although hormone will increase success rate while decreasing chance of infection. Take a full fine cutting of about 6 inches to a foot, or roughly 1/3 of a meter or less.

P.s. Don't fertilize trumpet vine. That will encourage leafy growth instead of blooms.

It needs some direct sunlight to bloom. It will have leafy growth in shade. If it is an old plant, try cutting half the stems to the ground this fall or winter. That may re-invigorate it. More tips are here: https://www.gardeningknowhow.com/ornamental/vines/trumpet-vine/pruning-trumpet-vines.htm

Q. Do you know what this plant is?

We just moved into this house and i want to take up gardening. I really like the way these look and was thinking of putting a trellis up. It’s grown quite a bit after we had a lot of rain lately.

It would not be wise to let that grow. That is Campsis radicans. This is a very invasive plant that will completely destroy foundation, sensitive plants and trees, and completely engulf structures. They also attract thousands of ants.

I would recommend getting rid of it manually, and then pouring boiling water over the area for a week. Make sure to kill any instances that crop up further away too, since the roots will send up new shoots far from the original stump.

I'm sorry that you have been plagued by this plant, and I hope that you can get rid of it before it destroys everything. This plant will laugh off harsh chemicals as if it were being watered, so get ready for a battle. Boiling water will kill just about anything with enough persistence.

Q. How do i grow Campsis ‘Indian Summer’?

I bought 2 Campsis Indian Summer plants last autumn and planted as advised. One plant has grown extremely well. It has one main shoot, which has grown to 6 feet and has many leaves. It looks very healthy.The 2nd plant, grown in another part of the garden, has not grown well, at all. It has no shoots, a few leaves but it had one flower! What I need to know is how do I encourage more shoots on both plants? Do I have to cut, the very healthy plant, back to where it shooted from this year? Approx 8 inches from ground level. What do I need to do to the 2nd plant to encourage more shoots next year? Any advice gratefully received. Thank you.

Indian Summer campsis needs little care. Plant in full sun in well drained soil. The vines grow rapidly, sometimes reaching 30 to 40 feet in one summer.
Try pruning your vines to encourage more leaf and stem production. Also, the underperforming vine could be moved closer to the other one.
