Terscheckii hybrids?

Recommended Posts

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! :)

I thought terscheckii were slow growers.

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 :wink:

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

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.

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..

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?

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! :wink:

Adding nitrogen tends to cause excessive (abnormal) growth and pupping

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.

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'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

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.
