Yellow Oenothera Species?
8 months ago
last modified: 8 months ago
This Oenothera about a foot tall with half-dollar-sized blooms and very narrow, serrated, ~1.5" leaves was found in some developed prairie remnant in Fort Worth. What is it, exactly?

is this a 8 foot tall oenothera?
Comments (4)I just happened to see this thread in the "recent posts" box. My Oenothera biennis is blooming now, way over my head. I'm 5'4" so I would guess it to be at least 7 feet tall. It can really overwhelm less vigorous plants quickly so I try to confine it to rough areas....See MoreOenothera Youngii (yellow primrose) - Invasive?
Comments (3)I agree with echinaceamaniac. One thing particularly nice about these plants is that, at least in my garden, they don't spread by spewing seeds all over the place. They spread by short runners so you get a very tidy result. In the spring you end up with cute little pads, each of which grows a new stem and flower set. You don't have to do a thing. One other lovely thing is that they need little water, if you didn't know that. I highly recommend this plant. Mine have been at my current home for 8 years and I'm always asked to share.

Comments (2)Hi Roger. Nice to see you posting here. I haven't a clue about the clematis but it appears to be quite an unusual one. Just an aside, the pitcheri seedling I had up last year didn't survive my one month absence this past summer. I also haven't had any germinations from the clematis addisonii seed you sent yet. On both counts however, I have subsequently replanted some of the seeds of both the pitcheri and addisonii seed you sent. One pitcheri seedling germinated in approximately three months. I soaked the seeds in hot water overnight as Joan (Bloomsorelse) suggested and think that might have helped hasten germination of at least one seed anyway. I am still hopeful about the addisonii germination and other pitcheri seedlings. I have planted some seed from both of my pitcheri plants as well. I do have a plant tentatively identified as addisonii that I obtained from the owner of a clematis nursery here in the US. Last summer was not a good summer for clematis in my garden--plenty of mildew, little rain, and extremely hot weather. The addisonii did okay and I am hoping to see it do better next summer. Once again, happy to see you posting here and good luck in identifying your friend's clematis....See MoreOzark sundrops (oenothera ?)
Comments (4)There are three species of Sundrops that are commonly found at nurseries: Oenothera macrocarpa (Missouri Primrose); Oenothera speciosa (Pink Evening Primrose); Oenothera speciosa (White Evening Primrose). Depending on supplier will depend on who calls what an "Ozark sundrop". The first one is a large showy yellow flower and is well behaved in the garden. The other two - just difference in color - they have smaller flowers that are pink or white. This species can get invasive and the one I think other posts are warning to stay away from? I have several O. macrocarpa planted in my garden. They die back in the severe heat of August unless they have some shade and/or moisture....See MoreRelated Professionals

8 months agolast modified: 8 months agoMany plants have several common names. That's why the scentific names are imortant. Calylophus has been reduced from a genus into a section of Oenothera. Calylophus berlandieri subsp. pinifolius has been elevated to species status and is now named Oenothers capillifolia. A type species can be secure in the wild, but it might jave a subspecies in danger of extinction. Giving varieties and subspecies species status helps protect them. I love seeing the histories about how the names evolved.
Oenothera capillifolia formerly Calylophus berlandieri subsp. pinifolius. Easy to spot with it's black throat.It is confusing that so many members of the EVENING PRIMOSE FAMILY are called SUNDROPS. Looks almost identical to Oenothera berlandieri in every other way.
