Discocactus horstii Adventure
Discocactus horstii Adventure
Dan Bach gave me these grafted plants -- nice gift!
They grow well that way, but I don't like grafted plants
So, off with their heads!!!
The de-grafts soon root up in my 80% pumice/20% pine bark mix as do seedlings
Now I am growing them (better) hydroponically (drain-to-waste) in straight pumice
Flower buds pop up in the afternoon
Flowers begin to open after dark
Flowers are fully open at midnight
Heavenly aroma!
Pollinating using a fine artist's brush produces fruit
Hybridization attempt: D. horstii x D. buenekeri
Objective: body coloration and spination of horstii but with buenekeri flower fragrance and offsetting
Didn't work!!!

Re: Discocactus horstii Adventure
Wow - fantastic plants!
Are Discocactus self-fertile?

Oooh! I love Discocactus!
I put aside my worries and bought a mature Discocactus zehntneri, can't wait for it to flower!

Buying a cactus a day will keep the madness away.
Re: Discocactus horstii Adventure
I am not sure, Tristan. I use a fine artist's watercolor brush to hand pollinate every Disco flower I encounter. I get good crops of fruit doing that. I don't know what the yield would be otherwise.Minime8484 wrote:.......... Are Discocactus self-fertile?

Re: Discocactus horstii Adventure
Great presentation as always, James! (And I'm glad you're still somewhat active on the forum.) I'll be on the hunt for a Disco horstii, although not before March. Miles Anderson told me that he'll have them available as grafted plants in spring. However, since I'm no fan of grafting, I'll try my luck with degrafting unless I can find a source for horstii on its own roots. Any thoughts on where I might look? I pose this question not only for James, but anyone else who might have an idea or two.
Thanks!

Re: Discocactus horstii Adventure
Steve, I've got about 15 of these plants coming along as seedlings. My Rx is to get seeds started now, while you shop for a more spendy mature plant.

I'll grow it as long as it doesn't have glochids. Gaudy flowers a plus.
Re: Discocactus horstii Adventure
James, your plants are truly awesome. I hope enough of my plants survive to maturity to look even remotely as good as yours!

Re: Discocactus horstii Adventure
Thanks, Steve. I saw some of Mile's grafted horstii when I visited with him last week -- they look nice. I will send you a bare rooted plant next Spring (or whenever). In the meantime, you should cozy-up to Barry Rice - it looks like you might be able to talk him out of a couple next year?Steve Johnson wrote:..........

Re: Discocactus horstii Adventure
Thanks for the thought, but I don't have the setup to grow from seed. Partly space constraints (9 square feet of bench space, and my apartment doesn't have the right space for seed growing inside), partly lack of free time to tend to the operation properly. Spendy isn't a problem, although I'll consider eBay only if A. it's a "buy now" option (I won't stick myself in a bidding war again!), and B. the horstii is on its own roots. If getting a grafted one ends up being my only choice, then M2G it'll be. While the thought of degrafting horstii may dissuade the faint of heart, I'm well beyond that point. With that said, I'd still like to find out if there may be other sources for rooted horstii without resorting to eBay. The hunt continues...BarryRice wrote:Steve, I've got about 15 of these plants coming along as seedlings. My Rx is to get seeds started now, while you shop for a more spendy mature plant.

Steve: it looks like your problem is solved.
Barry: I hope you do have great success with your seed raising efforts. I am too old and impatient to do that anymore. Thanks, Barry.
Part of my last seed raising effort of a few years ago (I have forgotten how many)

Re: Discocactus horstii Adventure
Those look great James. That species is amazing, they are very rare here too and I have never seen one in person.

Thanks, Bruno. I do envy you for your location -- do you plan a Bahia field trip soon?Brunãozinho wrote:Those look great James. That species is amazing, they are very rare here too and I have never seen one in person.
Re: Discocactus horstii Adventure
Hey James
I sympathize fully. I'd much prefer a mature plant but have seen none for sale. If I ever see a grafted one I'll pick it up and degraft it, based upon your success. Until then, I have no choice but to settle on seed propagation!
Cheers

Re: Discocactus horstii Adventure
Crossed wires aside -- thanks so much, my friend! I'll PM you when it looks like the growing season is about to start. The latter part of March is usually good, although our SoCal climate can be fickle enough to send out chilly weather into April. But hopefully not, and in any case we'll keep in touch on this.jp29 wrote:I will send you a bare rooted plant next Spring (or whenever).
I genuinely appreciate your thoughtfulness!
