How to Propagate Caryopteris

How to Propagate Caryopteris

Caryopteris was one of the new perennials I added to my garden last year. It did very well last summer and fall with some late season color. I’m so happy with it I decided I need a few more this year! I have an area that I have almost finished mulching and had an idea that required more caryopteris plants than I had on hand. I wanted to create a line of caryopteris plants to define one border of the new garden. Rather than go out and spend money on this project I moved two large caryopteris plants from other gardens to the area then took cuttings from the other caryopteris plants I have.

Caryopteris cuttings root very easily from internodal cuttings with greenwood or semi-ripe wood. I haven’t tried hardwood cuttings of caryopteris so they may root well too, I just don’t know. I’ll try it this fall and see what happens.

Here’s how to take caryopteris cuttings:

1. Take a stem-tip cutting just above a node.

2. Leave a pair of leaves on the cutting. The leaves were the only node I left on the cuttings. Two or three node cuttings may make a more established plant faster but I was looking for quantity rather than size.

3. Treat the cuttings with rooting hormone. You don’t really have to do this (for caryopteris) but I’ve found that it speeds the process up.

4. Stick the cuttings in rooting medium (in my case sand).

5. Wait 7-10 days and check for root resistance by gently pulling on the stem.

6. If there is resistance then pot them or plant them.

That’s all there is to it, very simple. You could even try just sticking the cuttings in the ground to get more plants but with the June heat already here it’s safer to bring the cuttings indoors to root.

I’m currently working on getting more ‘Powis Castle’ Artemisia to root. I managed one already but it is such a great foliage plant that I can’t stop with just one! Hopefully I’ll have a post to share on that soon.

Quick Propagation Tip: June is a good time to take crape myrtle cuttings and to start taking cuttings of asters and chrysanthemums (mums) for fall! Just take your pinched off mum leftovers and treat them like the caryopteris cuttings in this post.

  1. I am really into blue flowers. I like this one alot but don't think I've seen it here in Pa. What zones does it do well in? (I think I'm in the new 6 lol)How tall does this get? I believe I could sqeeze one in somewhere

  2. Artemesia is such a cool name for a plant. Much more elegant sounding than caryopteris. But hey, I'm being completely subjective.

  3. Nice I have started my crape myrtle cuttings last week. This is a great plant. Cherie it can get up to 36-60" Tall, and is hardy in zones 5-9

  4. That's it! Neat! It's so easy to propogate certain plant. I hope it's as easy to maintain them …

  5. Cherie,

    It's a good one for sure, very easy to maintain. In colder locations it may die back to the ground but generally what Ben said is true. Drought tolerant and sun loving!

    TC,

    Artemisia does sound a bit less dinosaurish than caryopteris. If you prefer we could go with Bluebeard or Blue Mist Shrub? 😉

    Ben,

    The crape myrtles seem to do best for me around June. I have about 4 rooted right now that I need to find homes for. They'll even root in water.

    Blossom,

    Very easy! Just pop them in a full sun or part shade area and let them go. After they are established they do fantastic. The deer and rabbits never even touch them and that is essential here!

  6. Thanks everyone for the info I definitely am going to look for it either at the nursery or in someone's yard-hey I now know how to propagate it! I can take cuttings;just need to carry my clippers with me.

  7. It's great that you can even GROW Caryopteris. I've tried three times now and all have died. I give up! It's so pretty when it does well.

    Dave, you are the KING of propagation! Great tips, always!

  8. Very clear and easy to follow. My sister has been meaning to try cuttings of my 'Carol Mackie' daphne — probably now would be a good time, when there's lots of semi-soft new growth on the shrub. What do you think?

  9. Dave, I read this last week right before trimming my caryopteris. I put some of my trimmings in pots & a few right in the soil of the flower bed & it appears they've already rooted! Thank you for the propagation hints!

  10. Susan,

    I'm glad to hear it worked out so easily for you! A very cool plant to make more of…for free!

  11. Caryopteris is a hugely valuable plant to bees and other pollinators as it is a source of nectar and pollen very late in the season when most other food sources for pollinators are gone. Plant lots for the bees!

  12. Is it too late to start them now if I put them on a heat mat?

    1. You might be able to do it fine but the problem would then become how to care for them over the winter. You would have a better result with trying hardwood cuttings outdoors. Then you don't have to worry about the winter temperatures. Hardwood cuttings will stay dormant until the temperatures warm up in the spring time and will begin rooting when they are ready. Just take a 6-8 inch hardwood branch from the carypoteris and put them in a moist location in your garden. Keep the spot weed free and don't allow them to completely dry out.
