Last summer when I planted Scarlet O'Hara from a pot a part of the root without eyes separated and I put it in a pot. It's been there all the time and I decided to look if it grew at all. Surprisingly it grew a few thin rots (they look alive) and the root itself did not rot. But still no eyes. Shall I give up and toss it or is there any hope that eyes will develop? Any thoughts?

Nothing lost if you give it more time.

If Scarlet O'Hara roots are adventitious, they will form eyes from root bits. Won't know unless you try. It may take a year or two for the root to develop eyes though.

I have (somewhere - thought my desktop) a list of the adventitious roots. Can't find it. Drat. Came from someone's website - a supplier but can't remember who.

Nate Bremer mentioned if a variety had adventitious roots. I am not sure Scarlet O'Hara was among them.

Here is the list of adventitious roots from Alan Rogers Book

Thank you, Mary! I noticed many of these are of Saunders. I added this info in my peony file, there are more varieties with adventitious roots, hopefully Scarlet O'Hara is among them. I will probably plant this root in the ground in summer, I don't want to throw away alive root.

I agree. I would plant anything just in case it should prove growable. Hmmmm. is that a word? lol

I had another list from somewhere but for the life of me can't find it. I was thinking Pink Hawaiin Coral was on that list

Tropicana is as well, info from the propagator. A lot of hybrids are according to people who graft tps, why they don't use hybrids as root donors if they can avoid it.

Ok, I found this list from Carol Adelman of adventitious Peonies.

I thought we were going to have a sticky note on the Forum. 🤔

Pink Derby will grow from a blind root.

LG, I think this was the list I coudln't find. I remember that I had to do two screen shots to get the entire list, then tape it together. So much for finding it. Have reprinted and will put somewhere safe. lol. I print so many things then after the pile becomes ridiculous I start pitching, only to start all over again.

Great! Thank you LG and everybody! What are the optimal conditions for growing adventitious roots? The pot with the root is by the window so the temperature is much lower than 70F but when it gets sunny the pot can get warm. I read somewhere that peoples place blind roots at 80F and it can take several months for eyes to develop. Is it right? I tried to grow eyes on a blind root from Carol in ziplock but it rotted, Carol is an officinalis hybrid. I might have done something wrong. Interestingly, there are 3 lactiflora in the list.

Shall I place the pot in a much warmer place?

I'm pretty sure they need the same cold to form eyes as eyed roots need to bloom. The only guide I've ever seen for them was planting outside, placed horizontally, 2" below the surface. And depending on variety it can be months or even years. I have a coral NOID that you can practically watch the eyes pop out on but Jack Nordick told me Tropicana can take 2 years to grow from eyeless pieces.

Liz, good to know. This root has been in the cold until 2 weeks ago, who know how long it takes to form eyes. I will plant the root as you said in the garden and forget for a while.

Anya, I just Plant the root pieces in the garden. I try to determine the top ( the bottom narrows) and Plant it an inch below soil level in my zone 7a.

Put a tag on it, because you will want to know the name and it takes quite a time for them to bloom.

It's fun!!

Yes, we need a sticky of the lists of those that grow adventitiously, Please and Thank You.

Bride's Dream and Coral Sunset grew for me from roots buried over a foot deep. The plant tops died in 2013 and I figured they were goners. But in the second summer after they died I saw little green shoots. Coral Sunset was in the middle of a rhubarb bed I had planted over that spot. lol. I ended up with two roots with growth, now in a safe place in the front beds. Both developed small (2-4") plants within a year.

As far as I know, Coral Sunset, Coral Charm, Cytherea, and Joker have readily formed eyes from blind root pieces for me. These peonies produce eyes in less than a year's time. Coral Sunset even bloomed within a year from newly formed eyes if the roots were large to begin with. I had some Alexander Woollcott blind root pieces that I buried from last fall. I will report back if any of these roots produce eyes.

This seems unlikely, but I had a shoot from Lemon Chiffon that formed perfectly about 8" from the original plant, with two eyes. Nate Bremer told me he's never noticed that LC grew adventitiously . I dug it up (so cute!) and gave it to my sister. Unfortunately she had a mini flood in her bed last spring and it rotted. We'll see in the future if it happens again.

Another of my LC.
