Haworthia cooperi v truncata name?

bikerdoc5968 Z6 SE MIApril 19, 2014

I recently was given the Haworthia in the middle. I have had the flanking plants for some time. Those are labeled Haworthia cooperi v truncata, but I'm not certain the one on the right is, in fact, H. cooperi v truncata and I don't know the name of the middle one although it looks like the one on the left. The middle one has a brown flower while the one on the right is green. The middle one may be H. cooperi v cooperi or maybe v obtusa. So names, please for these threesome?????

Thanks,
Howard

From what I can see in the photo and comparing it to Bayer's "Haworthia Revisited", I would say that the one in the middle is indeed v. truncata. I cannot see the other two clearly, but I do see them well enough to say they are NOT v. truncata.

Sorry Howard. i don't think you have Haworthia cooperi v truncata in any of them.It grows in a tight mound of rounded leaves. Haworthias are as big a minefield as the Echeverias.

There are plants sold as Cooperi truncate from Arid Lands.com, looks like grown hard, look at the pics. Little flat rosettes of little roundish leaves. The middle and maybe the right look like the one I got from them.

I wonder if some of the plants called Cooperi out there may be mixes that have longer leaves but retain some roundness.

An of course, etolation is another factor for confusion. Plants grown in a greenhouse may look different.

I, certainly, am well aware of the effect our individual growing conditions can have on our plants. These all have been grown under similar conditions in a greenhouse with bright sunlight; I doubt any are etiolated, but then what do I know.

Here are some closer views of the plants in the same order as they originally appeared above. I have had this plant for several years and purchased it from someone, who I believe to be very reliable about naming plants. It is labeled as H. cooperi v truncata.

This is the plant that I recently received and do not know for certain its name.

I don't recall where I got this plant but it had no tag and just assumed it was H. cooperi v truncata.

I've honestly never been able to tell the difference between those three... I have a Cooperii that grows in a tight truncata-like fashion but I just call it a Cooperii to make it easy. :P

I struggle with these guys, and yet I would give up all other plants for my H. cooperi. Of the three the third sticks out to me just slightly, but I really don't know. It doesn't ring out to me as H. c. var. pilifera, and certainly not H. cooperi var. cooperi, but I can see the slight difference between it and the other two. It's so hard to tell. I just wish all the H. cooperi varieties could be pictured more accurately online, for the love of all things good.

I've seen them all separately from various sources. I really think the names are a matter of "in the eye of the beholder" cause I have seen supposed truncatas that don't look different... then obtusas that look really different, then just plain cooperii that look just like the others. I know. Could be a locational thing.

Howard, I think all 3 are H. cooperi v. truncata (or form of). The one Bev showed from Cactus art biz, I always thought was H. cooperi v. pilifera (although they list that as a synonym-also lumped in obtusa). Hard to say...as you know...difficult to ID, especially when it sometimes depends what area they came from to narrow it down.

The one book I own on Haworthia, have tuncata & pilifera listed separately & don't list obtusa at all.

Sorry I can't be of more help!

Rosemarie, you are always helpful just by offering your opinion. And thanks to all for your input, it is very much appreciated. I know all too well identification can be difficult at best with so many environmental influences. For me, knowing at least that it is Haworthia cooperi is great!

OUCH.... SPRUNG !!!!!!! Yes I did take it from the internet.. clever girl !!!!! I wasn't sure if I could get the page of my Haworthia book under far enough to scan well enough. Did get enough to see what it looks like. Sooo this plant pic was taken in an actual collection of one of our most prominent very long term Haworthia collectors. The plant I have came from him, but it's not currently pic worthy. There are about 18 different H.cooperi varieties depicted in the book

Bev, I'm not a "book" person but am interested in the title of the book you scanned for the above pics.

Also see you fancy Echeveria... would love to see as these are one of my favs, also.

It's "Haworthia for the collector" lotsa pretty pics, written by Rudolf Schulz one of the Echeveria Cultivars authors. Hawortha were my first succulent choice when I started collecting in 1970.. I still have about 500 of them. Echeverias came later around 1977, have specialisted in them since,Imported them from all over the world since 1980 but still love the Haworthias too. As I said in previous post, they have become the same minefields as the Echeverias.. Below one of 12 pics on my Facebook page. This is part of my main Echeveria collection. I have a 40ft x 40ft shed with more and the other species in it as well

Those are very nice, indeed. Thanks, Bev. Is it safe to assume you live someplace with lots of warmth and sun? I would love to visit your Facebook page to see your other pics...

Fabulous shot of a GAZILLION Echeveria!! I LOVE it!

Wait a second, Rosemarie. Bev's profile says she lives in the USA. Are you saying this is Bev Spiller? If so, I believe she's in the Melbourne area, but I'll let her chime in. Now, I am confused...I'm going out to the greenhouse and stare at the plants until I recover!

Hee hee, Howard...revisit some (Echeveria) posts from last month. You were clear then who she was. :P But, Bev can tell us, too!

I thought that was her but when I looked at her profile as saw, "Lives in the USA", I got confused. Her handle looked familiar to me. I'm much better, now. I spent an hour just staring...LOL

Yup. I'm the Oz Bev !!!!!!! Haven't looked @ the the profile.since i joined years ago. I live in Queensland about 100 miles north of Brisbane, Echeverias luuuuuuuurve our Winter [ well what we get as Winter rarely a zero ] but struggle with the humidity in Summer. so it's always been a challenge to get what has survived the Summer on track again. Last season ... June to mid Nov.... they have been the best ever... as you can see by the pics. there is about 300 in that outside area..approx 12ft x 12ft I have a solarweave cover and shadecloth for the Nov / March period. Survival rate much better since I set that up. .EEEk tried to change the profile, but won't accept my address. will leave it as it is methinks
