Berengar Posted March 23, 2014 Hello everyone! Recently I started wondering, why aren't T. terscheckii hybrids more popular? On paper, it seems like a potentially perfect combination, large, thick, beautiful, fast growing, cold tolerant columnars! But the seeds are practically impossible to find. Why is the reason for that? Do they hybridize easily with other species and produce normal number of seeds? Or are people generally more interested in various bridgesii and pachanoi hybrids? Flowering-size T. terscheckii specimens are also probably more rare in collections. Is that the reason? I'm sure lots of folks would love them, especially people like me who's winters are just a bit to wet to keep faster growing Trichocereus species outside year round without complications. I would implore anyone with flowering specimens of terscheckii and other Trichocereus to give hybridization a shot, and sell or trade the seeds to the community! Is the flowering season over in Australia? Thank you very much for reading! 3 Share this post Link to post Share on other sites
Halcyon Daze Posted March 23, 2014 (edited) I thought terscheckii were slow growers. Edited March 24, 2014 by Halcyon Daze 2 Share this post Link to post Share on other sites
Berengar Posted March 23, 2014 (edited) They are. Very slow. And grafting them doesn't work nearly as well as with other species. That's exactly the point of hybridization, making them much faster growing, and at least some of the offsprings would have the cold resistant properties of T. terscheckii. There were some Psych0Xterscheckii seeds available at some point, those plants look simply amazing and have the growth rate of Psycho0!

Cold tolerance is a major plus for many growers - Terscheckii and Taquimbalensis hybrids with other favorites 2 Share this post Link to post Share on other sites
Brendo Posted March 23, 2014 (edited) Yeah I've had mine in the ground for 18 months, hasn't put on an inch. It was about the size of a tennis ball when I purchased it, since then it's fattened up a bit but that's it. Would be a great idea. Edit: planted in the ground Edited March 24, 2014 by Brendo 1 Share this post Link to post Share on other sites
AZS Posted March 23, 2014 In Phoenix, my Terscheckii seedlings more than double in size each year for the first several years then put on at least 6 inches per year and sprout arms readily. Terscheckii can reach over 10 meters in height and easily weigh over 15 tons when fully grown. They can easily handle temps down below -7C / 20F If more people continued to plant them ( perhaps for the next guys) the argument over how fast they grow wouldn't be an issue. 2 Share this post Link to post Share on other sites
Jack Posted March 23, 2014 Brendo that's how they grow they get really fat then at a point they will start to grow upwards.. Mine took years before it started getting taller.. 1 Share this post Link to post Share on other sites

Stillman Posted March 23, 2014 There are some hybrids around PD had some and the offspring must be pretty big by now? Share this post Link to post Share on other sites
Berengar Posted March 23, 2014 AZS, I definitely plan to grow them, I just ordered some T. terscheckii, T. taquimbalensis and T. werdermannianus, but I would also like to play around with more variety while I'm waiting on those to be ready to be planted in the ground! Both purebreds and hybrids have their own special charm for me. How many years does it usually take for your plants to start growing columnar? 1 Share this post Link to post Share on other sites
AZS Posted March 23, 2014 These plants need full sun after about 3 years old to do their best - most people baby them way too much! My "pure" Terscheckii start to take off vertically at about 3 years - they grow all year long here, just slow down in winter. Hybrids - grow them and find out! Adding nitrogen tends to cause excessive (abnormal) growth and pupping 12 Share this post Link to post Share on other sites

Halcyon Daze Posted March 24, 2014 look out for validus crosses too 3 Share this post Link to post Share on other sites
Jox Posted March 24, 2014 Here are some Terscheckii hybrids, These are T.terscheckii X T. pachanoi 'Huarazensis' & are just over three years old, been growing very slowly but are finally starting to show some growth & getting some nice spines. One of them is looking a bit different than the other two. Cheers Jox 9 Share this post Link to post Share on other sites
EthnoGuy85 Posted March 24, 2014 I just started some Echinopsis x terscheckii and terscheckii x Echinopsis crosses a few days ago should be interesting Share this post Link to post Share on other sites
mushroomman Posted March 24, 2014 I love terscheckii hybrids here are a couple of mine. Terscheckii x psychoo at back. Rosei1 open (prob got ters or pasacana in it ) Short spined ters x psychoo. Validus x rosei1 13 Share this post Link to post Share on other sites
interbeing Posted March 24, 2014 The validus x rosei1 are looking awesome, can't wait to see how they develop Share this post Link to post Share on other sites
Berengar Posted March 27, 2014 (edited) Thank you everyone for the beautiful photographs! Makes me want to start collecting those hybrids even more! Does anyone have any pictures of some T. taquimbalensis (and related 'species') crosses? I've started a couple of Zelly's validus hybrids, can't wait to see how those turn out! And some T. werdermanianus, T.tacaquirenis and 'spineless' Bolivian T. terscheckii from a vendor, this is gonna be an exciting growing season!

I can't wait to get some of your pach x pasacana seeds going just have to make some room for them. Share this post Link to post Share on other sites

Getafix Posted March 31, 2014 I'll get in on that if you want to make an order. Haven't seen that cross before. I just bought a heap of Taquimbalensis seed from Cactus Plaza and have had awesome germination rate. Hope they are what they say they are Share this post Link to post Share on other sites
mushroomman Posted March 31, 2014 Here is a pic of my degrafted one not the nicest looking plant ATM was grown in low light for to long will get another pic of it when I go to my dads this week am very keen to put an order in but will have to find out if they have an online payment option available again. I'll pm you the seed list on the weekend. 1 Share this post Link to post Share on other sites
