Coreopsis Tripteris?

| Does anyone grow this? Is it really a thug?
It's on sale at Bluestone right now, and I am intrigued but a little afraid. I found some threads that used the words "monster" and "killer roots." |

| I love this plant, a magnificent native. Handsome foliage all season and great butter yellow daisies in summer. Not a thug, though it does spread slowly from roots. Not too difficult to root prune back every few years. |

| I think the "monster" description would primarily be referring to its relative size at 4-10' (1-3m). So it would need some space! It also self-sows somewhat readily. |
RE: Coreopsis Tripteris?

| In my garden it self-sows moderately, but doesn't appear to spread from the roots much. It may be more of a problem for you, since you're in a warmer zone. The self-seeding may become annoying. |

| I've never had a single self sown seedling. And I've grown it for at least 8 years. |

| In my experience, a lot of "self-sowing" is dependent of how you "keep" your garden, i.e. whether you mulch, etc. Of course, there are other factors as well, including climate, birds, etc. |

| Thanks for all the replies! I think I'm going to go for it! |

| I trialed this for a number of years and was disappointed. It was not a tidy plant, flopping quite a bit. The deer nailed it half the time so it almost never bloomed, and when it did, many seedlings appeared. I did not think it worth the space it occupied, but could see how it would be lovely in a meadow-type garden. |

| I've wondered about the deer resistance of this tall coreopsis as I love the look of it. Interesting that they took out yours. I have no deer problems with coreopsis 'Redshift' that is growing en masse right at the top of the meadow where the deer traverse each night. I'm currently conducting trials for TN Nurseries - 3 varieties of their coreopsis for zone and deer resistance. So far, no deer problems. The tiny plugs of short coreopsis bloomed until the end of November and the deer didn't touch them. Of course, deer resistance varies by herds and gardens. Cameron |

| Oops, I have to plead a brain blip. For some reason, I had this plant confused with Rudbeckia triloba in my head. I have not grown C. tripteris, so please disregard my comments about it. When Cameron pointed out that deer never touch Coreopsis, the gray matter clicked into place. She's right. I've never had deer ruin my coreopsis. Sorry for the brain blip and misleading info. |

| Coreopsis tripteris is very tall perennial, and the small birds like to eat its seeds when ripe. It stays upright despite its height, and is really quite a "neat" plant. Will grow in sun or part shade. Rudbeckia triloba is an annual/biennial black eyed susan that truly likes to seed around (just like many biennials!). |

| I'd like to grow this beside my bronze fennel in the butterfly garden, so thanks to the OP for asking and others for the info provided. Cameron |
RE: Coreopsis Tripteris?
| | |
| Oh, Cameron! I have bronze fennel!! I think I will steal your idea if you don't mind - that sounds like a perfect combo! :D |
RE: Coreopsis Tripteris?
| | |
| Connie - I think the two will pair up well! :-) |
RE: Coreopsis Tripteris?

| I ordered some of the C. tripteris also. I've been trying to get a sunflower & other tall yellow flower garden started for the birds and as a backdrop to my bulb garden. C.t. looked like it just might do the trick, so it has been very helpful to see the various comments in this thread. Thanks! Brandyray |

| I've grown this plant for years - very tough and forms a very thick root system. I really like the fine textured foliage. Agree with comments above. Other points to note - it will take drier sites in full some with some midday wilting but prefers some moisture if in direct sun. Makes a good rain garden plant or nice tall perennial for a low area in the yard such a ditch or bottom of a slope. If you've got the room I think it looks great paired up with Ironweed, Joe Pye Weed and Culver's Root. |
RE: Coreopsis Tripteris?
| | |
| I find that Coreopsis are great plants for the 'edge' of the garden; the parts that don't get as much water, don't get as much care, frontlines of the Deer war, etc. All mine are in a bed full of bearded iris, another great edge plant in Oregon. I haven't noticed any mass of seedlings invading my lawn, but then again this is a horrible rental lawn so I really don't pay attention. |
