Creeping Buttercup (Ranunculus repens)?
This small forb was found growing along a creek. Is this actually Creeping Buttercup (Ranunculus repens), unlike the other, similar one I had recently posted? One questionable part is that I didn't look much, but I didn't notice any characteristic stolons, though? Or is it something else?

What's your next perennial cut flower right after Narcissus?
Comments (17)This is a great thread, even for those of us who just grow our own cutting flowers. What do you think of chives? Their color is subtle, but they are prolific perennials. I have yet to get garlic chives started, but they are white, and must be pretty. The chive flowers don't give off an onion-y smell that I have noticed. Oh, I see you do have them listed. This one is a bit informal, and draws up a lot of water when cut, but it is also prolific: lunaria aka silver dollar plant. It comes in white and, most commonly, a rich pink-purple shade. I have seen in a a very dark magenta, in other gardens. It is biennial, which means you need to start them two years in a row, and then you will have them forever, if you let even a few go to seed. Bridal veil spirea is coming in to bloom now, as the very last daffodils are fading. I second the wood hyacinth and bleeding heart suggestions. Interesting, how most of the suggestions for now generally have subtle colors. Doronicum breaks that pattern, as do many of the tulips, if you decide to go that route. I have some burgundy and yellow bi-color primroses, as well as a few solid yellow double primroses that have 6-7 inch stems, and last up to a week in water. They have a nice long bloom season too. These started almost three weeks ago here in mid-atlantic 7a and they will continue another few weeks, depending on the heat. They look nice in small bouquets with buttercups and japanese maple sprigs with baby leaves. A lush, long-lasting green that I discovered this year comes from my overwintered parsnips! Siberian irises look like they are coming soon. I wonder if a clear plastic cage over each plant would hurry them along. That said, I do not find that they last well at all as cuts, though some catalogs say they do. I started growing camassia last year. I see they are starting to bloom now. Not very impressive, I must say, but maybe there are showier varieties. I bought the cheapest, species type. Apparently they naturalize well where they are happy. Good luck!

Comments (7)I just treated it with a Roundup product for weeds in lawns. Says it will kill many things including buttercup. I also purchased Scotts Turf Builder with weed control. I did not spray it as container says to not spray within 48 hours of watering or expected rain and we are expecting rain within that timeframe....See MoreWeed or wildflower?
Comments (6)It is a Ranunculus sp. If you did not plant it I would say it is a wildflower/weed depending on your point of view....See Moreblakrab Centex
last yearOK, so I let one of these bloom just for ID purposes and...it looks like it IS invasive Creeping Buttercup (Ranunculus repens)...not to be confused with Anemone berlandieri (Tenpetal Anemone).
Well, looks like I'll be composting it now!

last yearlast modified: last yearIf a Ranunculus species isn't easily identified by obvious charecters, ie (white, LIGHT) leaf markings near the sinuses= R. repens, than it must be keyed with the plant in hand. They can be so similar that they require looking at the leaves, sepals, petioles, leaf undersides, stem, petiolules, roots, flowers, basal leaves, cauline leaves both lower and top near flowers, fruits. I wouldn't post anymore questionable Ranunculus species. The photos don't show sepals, leaf undersides, adaxial. There is no clear indication of which leaves are basal and which are cauline. The photo shows pubescence, but the quality is far from showing exactly what kind of pubescence, pilose?, hirsute?, hispid?, etc. Judging from all the Ranunculus species in the Dallas area you can eliminate repens, fascicularis, muricatus. This plant could be a variety of the Ranunculus hispidus complex, or Ranunculus sardous,( which I'm not familiar with). This genus of 600 species is broken up into sections, and only certified botanists can view that online info, or there's a book I think by Lyman Benton. There are quite a few Ranunculus hispidus varieties, but nothing online that I can find to key them out. Good luck!
Some Ranunculus species are so similar that the only way to ID them is by measuring the achenes, or by the locations they are growing at.

last yearlast modified: last yearRanunculus hispidus has 1 sure way of being identified. The flower petals become transluscent near the flower center. Your 3rd photo looks like maybe the petals are transluscent towards the center. If it's not hispidus, then I have no idea what else it could be. I'm assuming all the varieties have this same trait, but I can't find any information about them to be certain.

There is also a variety nitidus not mentioned by Weakley, probably because it doesn't occur in the southeast. Texas isn't mentioned in the flora as part of it's range, but hispidus is definately in Texas. If it's not hispidus, then it must be sardous.blakrab Centex thanked Jay 6a Chicagoblakrab Centex
