    Maintenance Notes: 

    Caryopteris demands a sunny spot and very well-drained soil. Wet soils, particularly those that remain soggy during periods of cold weather, will cause root rot. For this reason, we recommend early season planting of caryopteris in zones 5 and 6.

    Caryopteris should be cut back every spring to ensure sturdy, dense growth. You may give it a light trim in late autumn, once it has gone dormant, to remove the old flowers and eliminate possible seed spread. However, do not cut into any thick, woody stems until new growth begins to emerge in spring. Then, cut the whole plant back to just above where large, healthy buds are emerging.

    Fun Facts: 

    Caryopteris is also known as bluebeard or blue mist spirea - but it's not a spirea at all. In fact, they're not even remotely related.

    • Planted in early/mid-summer 2018 and it did really well until winter. The rabbits destroyed a good part of the plant during the winter, but not enough for it to not survive. They destroyed many other plants and those have all come back fine- a bit smaller but still healthy. I attribute the cold winter to this one not surviving. As beautiful as it was, I won’t try this again. I will find a heartier perennial with like-color to plant in its place. Based on other reviews that are similar to mine, I imagine zones 6-9 have better luck with this plant. Zone 5 winters have been colder these last few years and I think they have a hard time surviving the extreme cold. Had it survived, it may have become my favorite plant. The color and amount of blooms were mesmerizing! It became covered with bumble bees so keep that in mind while choosing a location.

    • Bought in spring of 2018. Grew fine but did not bloom until August. The blooms were very sparse but I attributed it to transplanting. Trimmed it back very early spring this year, but to date there is no new growth. very disappointed as it cost just under $30.00.

    • Adds a beautiful contrast to my other foundation perennials. Blooms late into the summer, after the daylilies are done.

      Outstanding My favorite plant, I recommend to others all the time and explain the reasons why I like it so much.
    • I love this plant and ordered two of them as well as four of the two yellow versions. I have double dug flower beds with plenty of compost-- sun from morning until 2 PM, then a couple of hours in the evening. My lilies in this bed do well, so I assume the drainage is good. One plant did not come back after winter. The second did well until about the 4th of July, then, quite suddenly, it started to "wilt" and was dead within a few days. The larger of the four yellow ones was still going strong until last week. I see one of the spectacular big yellow ones has started to wilt as well. I have pruned the dead parts out, but they keep coming. They are neither under nor over watered. I can't see any kind of bug on these plants, and those plants interplanted with them are doing fine. Breaks my heart because I built one whole bed around them for my daughter's outdoor wedding at the end of August. They are among the few perennials in bloom at that time. Too late to try and replace them with something big enough for their function in the bed. I've been gardening for 30+ years and rarely have losses. I have no idea what I did wrong, so am afraid to order again at the hefty price plus shipping.
