It is disappointing that the old crew of experts that combined responsiveness with the breadth and depth of knowledge that made NameThatPlant such a useful resource for gardeners appears to have taken a leave of absence, as demonstrated by this query being completely ignored (not a single answer in two weeks).

What a better opportunity to try out one of those online plant identification tools.

We submitted the above picture to Pl@ntNet and the top hit obtained was Ludwigia palustris. While its leaves appear to be similar to our plant and the species name "palustris" indicates a swamp plant, L. palustris can grow up to 20 inches tall - not in agreement with the ground hugging habit of the subject. But there is also another species, L. repens that appears to be a good match, including a reddish tint to its leaves. Not unlike many other swamp plants, L. repens can grow fully submerged and indeed it is commonly used as an aquarium plant.

We conclude that the plant pictured above is Ludwigia repens and we highly recommend it as a ground cover for boggy areas - because of its tight dense growth and great weed suppression capabilities.

Thanks for coming back with a follow up.

I check this forum daily, often more than once, and do not remember seeing this photo before. Most photos are IDed within minutes of posting. However, some posts don’t appear for more than 24 hours after posting for some unknown reason, and by then may be well down the list of forum topics and get missed because despite the delay, it still gets put in the post listing by when it was initially written. While it may not be the exact same group of experts, many of us have been here on GW for yonks and are pretty adept, so it isn’t likely that folks were ignoring you or that the forum is inactive but that the poor quality of tech expertise among the Houzz staff means that your post never was seen by most if not all of the posters on this forum. This only happens occasionally, not all the time. You are welcome to use whomever you want for your plant ID, but despite your unfortunate experience we are still quite active here and there is a lot of expertise.

Yes, I have noticed it several times myself. Just one of the tricks Houzz like to play on us. Another, affecting only me, is that it doesn't let me change my user profile to include my location. So, NHBabs, despite of your suggestions, I will remain simply windberry, regardless if I like it or not :-)

I posted last year about a similar plant which had flowers at the time, later in the season.

Windberry, Houzz won’t let you add a last name on the My Houzz page?

Thanks, everyone for your feedback. We are aware of some problems with messages not appearing immediately and always check the forum index after posting (editing a stalled message may push it out). The lead message of this thread showed up without delay and over the next few days we saw it slowly ride into the sunset and obscurity of the second page. Together with two other threads we posted to, but those were less critical as they were only updates (on yucca and carex ids). A useful feature on the forum index is the "Unanswered" tab, which may be good to check out from time to time.

Thanks, Carol23_gw, for linking your relevant thread. Jekeesl who identified Ludwigia palustris (the larger species) there is certainly one of the experts whose contributions are being missed as he was highly knowledgeable about the natives from Southeastern US and helped us identify some obscure plants in the past.

Sorry CasaLester for this digression from the main topic of this thread.

Yes NHBabs, it rejects all my efforts to change my user name from windberry to windberry zone5a BCCanada.

I don't recall this picture either. And I'm here almost every day. As is Jekeesl. I don't know why you think he's no longer here. He posted yesterday.

Same here - check regularly, never saw this post. Go home, houzz, you're drunk.

Windberry, it is not your user name that you want to change. In the next section under profile information, the first two boxes are for your first and last name publicly displayed. You can put zone info in the last name box and that should work.

Thanks NHBabs. Would never have this idea! So far I had that box empty. I had to put into the box my user name together with zone and location, otherwise Houzz displayed only what was in the box, ignoring my user name. Rather funny!

Sorry again CasaLester.

purslane

It isn't Purslane. Apart from not looking like purslane the latter doesn't grow in damp areas.

Ironically, some of the common names of Ludwigia palustris are water purslane and marsh purslane. However, without any qualifiers, "purslane" alone will be interpreted as Portulaca oleracea, a drought tolerant succulent.

Yet another illustration of why common names are not very useful and create confusion in plant identification.
