  • Hi Bob, To answer your question, I saw a plant over at the Huntington Botanical Gardens that looked like the plant I have pictured. I found the plant at a nursery in Tucson marked as C. childsii. the link to the nursery is: lithops.net . Unfortunately this plant has had a tough time in the heat of Phoenix, but is still struggling along. I am hoping all the rain we are getting will improve it's condition (I also watered it with some Superthrive a few weeks ago).

  • Hi Bob ...I've seen your photos and website..I'm hoping you can tell me what you know about Backeberg and his expeditions to S.america in the 1930's. I'm looking for info on Victor Morawetz, that sponsored some of Backeberg's expeditions to s.America. Can you tell me if in Backeberg's books (I can't locate any copies!) he mentions Victor Morawetz and the cactus that Backeberg brought back from S.America to Morawetz home in S.Carolina? I hear there is a photo of the cactus at Morawetz home in S.Carolina..can you help me??? thanks! John

  • Hello Bob, Love your chilensis pictures! On one of many trips to Berkeley Botanical Gardens, I fell in love with the chilensis there. They have what appears to be two seperate forms; one in the "New World Cactus" area and one in the "South America" area. I really like how the ribs are seperated into intervals, divided into large tubercles [as described by Britton and Rose]I noticed that you have some grown from seed.....do you have any more recent pictures of them for comparison? Also can you point me in the direction of a seed or plant supplier. I would really like to add these guys to my collection. Any help would be appreciated. Thanks for the time, E

  • Hello Bob, I am writing to see if you have encountered a cactus that I believe is a cross between a Cleistocactus and an Oreocereus. I acquired it many years ago from Western Cactus, in Vista, California. I can send you a photograph, if I have your e-mail address. Jerry Wright The Great Petaluma Desert

  • Hey Bob, i am really amazed by your collection - i have been a fan of your work for some time. I have recently started collecting columnar cacti and recently bought this: http://good-times.webshots.com/photo/2137415540104169860yXpWdi It is quite an interesting specimen, i would like to hear your thoughts on it - i have my speculations but i am still very much a novice when it comes to cacti. Your input would be greatly appreciated! Thank you, Chris.

  • Hi Bob, I am new to this website, and I was wondering if you could identify the cactus in this particular picture. I found this while browsing the web and I am not sure if the ID is correct. I was told that it might be a cross between a haageocereus and a espostoa. Have you seen any plants like this before? I am looking to acquire one. Thanks.

  • Hello Bob, I hope that all is well. I got your message about the Peruvianus. I was at Poot's the other day and we started talking about the collection you had in the Central Valley. I wish I could have seen it, sounds GREAT. Bill said to say Hi! I am looking for a T. Huancoensis and T. Santaensis, any ideas on someone that might have cuttings. Any help would be huge, about the Peruvianus, Let me know.....Thanks,

  • Bob, You have a photo of Stenocereus martinezii, just wondering if this plant is available anywhere? It is one of my favorites and the picture is of a seed grown plant. Also, I see you visited my friend with the Backebergia militaris, hopefully he was able to spare a cutting. Any help on the Stenocereus martinezii would be greatly appreciated. Thanks, Greg

  • Thanks Bob, I really like the Peruvianus that you acquired from Dunsmuir. Do you know any good sources in the central valley (Ca) to obtain Peruvianus? I know that you were originally from this area and any advice would be great. I have purchased a few from a local grower but want to find other variations. I really appreciate all of your help.Thanks,

  • Wow Mr. Ressler, you have some great pictures of the different varieties of T. peruvianus. The picture of form #3 from Dunsmuir gardens in Oakland is outstanding. I have been collecting for about a two years now and really concentrating on the varieties of T. peruvianus. I wish that I could find a specimen that nice to add to my collection. Thanks for the pics and info, I will keep hunting. goldandcactus

  • I have a question. I recently purchased a Lophocereus schottii variety which I have never seen before. It is at least twice as thick as the thickest one I have ever seen and the areoles are inches apart, similar to the monstrose variety except the spinantion is like the type species. I also understand it flowers all along the stem, not just at the top pseudo-cephalium. I wonder if you have ever heard of a Lophocereus mixed with a Pachycereus or a Carnegia? It is at least as thick as my Trichocereus terscheckii, but with only 6 or 7 very large ribs. Any help would be appreciated. Greg

  • Hello Mr.Ressler, I'm sure I can send you list of available Trichocereus species. I have plenty of seedlings and can probably just send you some. If you can supply me with an e-mail address I can send you a list. Beautiful photos by the way,I am blown away by your two pictures of T.tulhuayachensis,very nice!

  • Hello Bob, I'd like to know if you actively trade trichocereus species? I have a substantial collection and am always looking to expand and help others expand theirs. Thanks, pellotine

  • In reply to your ??'s about my fish, the black-barred myleus are a type of silver dollar and experience the same behavior patterns. They do reach a dinnerplate size but htis takes a while. As for the prochilodus, grows to 12" and does resemble a tinfoil barb however, it is a characin(tetra), not a barb. They are renowned for their algae eating abilities but will take prepared foods. Like your cacti!! Scott

  • Bob, I did a websearch for neodawsonia and your pix came up. I was determined to get one based solely on the pictures in the Innes & Glass book, among other rare columnars, but never succeeded. I was looking early 1990's before the advent of the web. Ended up falling in for copiapoas after I went to Shein's in Seaside. Still ended up growing some very rare columnars from seed thanks to a German supplier. What's your secret and how can I get a neodawsonia?
