Hey guys, have a few Rose of Sharron's and last fall when I trimmed them back I took the clippings and put in a bucket with root started for a month then, before winter set in I set them out.

I know you can start them from clippings as I did a couple the year before.

We'll here we are May, the Rose of Sharron's I trimmed back and the ones I started from clippings the year before are now growing and have leaf's but the ones I set out last fall are just, we'll a twig in the ground? :confused:

However they are alive, I can scratch the bark with my fingernail and its green underneath. So do I have a reason for concern or am I jumping the gun?

Thanks in advance

Rose of Sharon is a common name and is used for at least a couple of different plants around north america.

Do you have the Latin name? Is it a groundcover with a yellow flower
or a flowering shrub?

If it's groundcover ie: St. John's Wort/Hypericum, those cuttings won't all come back in my experience and you just have to select the ones that are responding well.
If they're green, then just stick them in the ground in a low profile area
and see what happens

I don't believe you will get 100% regrowth from shrub cuttings either

Rose of Sharon-----Typical common name for Althea!
I haven't had the success with stem cuttings as I have with Forsythia.

That's the shrub I was thinking of. Hollyhock is Althaea rosea

See how common names differ around the world.

Sunset Garden Books uses the common name Hollyhock, but doesn't mention it as Rose of Sharon.

They call Saint John's Wort, Rose of Sharon.

I had a client years ago that called her Hollyhock a Rose of Sharon.

That's why we use Latin names. They remain the same all over the world,
and then other horticulturists know exactly what you are looking for.

O.P. If this is what you have, stake 18-24 inches apart. Water well
They can get rust and anthracnose.
It also says to wait for warm weather to set them out.

I'll get some pics and post tomorrow along with some of the original bush I'll have to hunt for it through last years photo's when its in full bloom.

As for setting them out, fall of the year is best because thats when you trim the bush back. You don't have the clippings before fall.

Also, as I said in my original post I know it will take root as I did it the year before with about three clippings and last spring they came out beautiful, roses on them by June and lasted all season. That's why I decided to do more last fall.

Here yu go guys as promised.

This is the bush the clippings were cut from last fall, the one to the right was started from clippings 5 years ago.

The second, I started from clippings in the fall of 2009 and came out last spring just amazing, had flowers and all.

Here's the one's I started from clippings last fall. I had them in a bucket with root starter for a month prior to setting them out. As you can see, just a twig in the ground, no leaf growth like on the two above???

However, green means life right? Scratching the bark of the one's I set out last fall reveals life :dizzy:

Kirk, yes green means there should be live cambium. The new stems cuttings may not be as vigorous as the older batches because of the harsh winter you guys had this season. These plants are temperature sensitive like the Crape myrtle and only come out when the time is right.
This is the common Althea that i was mentioning. You are in Kentucky not too far off from me to misidentify your vernacular.

Are you doing these cuttings for your own personal use? I would hope so!!!

Different names because of different locations. It looks like a hibiscus from the leaf. Hollyhock has a fig tree looking leaf. It is a tropical plant that we have to protect from cold temperatures. Kentucky is just a little too far north for the cuttings you put outdoors to survive. That isn't saying that they cant. But not generally.

Yes TG, the cuttings are for me on my own personal property; what bothers be is the clippings I put out in years past (always in the fall) came out the following spring perfectly.

So it sounds like your saying give it time due to the hard winter?
