No, they will get tall even in a small container unless you keep clipping them. With overwintered containers, I always subtract a zone or two in terms of hardiness. Brazilian Verbena probably won't survive a true Zone 6 winter in the ground, let alone in a container. I would hang onto the seeds until Spring.

Here in zone 4 it's a re-seeding annual.

I have 'September Charm' already and just purchased 'Honorine Jobert,' probably the most famous one of all. I feel like I just can't not have it in my garden. I bought a gallon size so the roots are a little farther along than the quart size which should help it establish before frost with a late-September planting. But, it does appear from the previous posts that these are tough plants.

Agree they are tough. Love mine (Honorine Joubert also plus some bright pink ones that DH constantly weedwhacks and still they return and bloom beautifully). My guess is that yours will be fine-just keep them watered as you would anything until established.

Not that I disagree with any of the discussion. I agree with an 'on site' evaluation. But ... I'm curious if anyone has considered the option of working with what you have and use plant material that prefers moist conditions and wouldn't mind the poor drainage? Not having a spot on my property that is 'moist' I don't have a list of plants but plants grow in marshes, so I assume there are some.

There is a lot about this discussion that strikes me as a bit 'off'. I've been trying to put my finger on it for a couple of days now, and it definitely revolves around the idea of messing with something that may not want to be messed with. It looks like a reasonably steep slope, and it is possible that any of this amending will either destabilize it, or just generally make a mess. For one thing, I'm not convinced that poor drainage is going to be any problem whatsoever for plants actually planted there. Slopes don't tend to be wet. Particularly something that looks like that, I'd expect most of the rainfall to run down the surface.

You might want to spend some time on the Tree forum, and get their views on amending planting holes. It looks like a decent variety of plant life can live there on their own, and I'd be very reluctant to fuss and possibly make the slope unstable.

By "almost immediately," I meant within a couple weeks. I put the seeds down in late June (temps were definitely warmer than 65-70 degrees) and less than a month later I had little babies. To me, that is pretty fast. But I wouldn't sow now in Michigan and expect them to survive winter.

morz is right.. there is NOT enough time to germ and grow enough before winter.. we had two frosts this week ... which means a freeze is not far behind.. probably before germination would happen ...

and they are NOT houseplants .. or at least wont be easy as such ... unless you have a light stand.. greenhouse ... perfect humidity .. etc ..

but my key is always along the lines ... presuming you have a volume of seed.

mark an area.. scratch a few into mother earth .. and mark the spot so you remember next spring [thats a big key.. lol .. nothing like remembering what you did.. a day or two after you weeded them out.. lol ..] ...

put a few in a pot.. and put it in the garage.. keep it moist all winter.. just put an ice cube on it once a month or so ... after the ground freezes ...

and try a couple in a pot indoors..

cover all your options ... experiment ...and learn ...

there is no real need to figure out the one true way ...

Ken, that is not a very large tree :-) Check the scale - it's growing in a bed of heather. The photo shows one about 3' tall at the most. FWIW, this is a dwarf conifer and only gets around 8' tall, maybe as much as 15' over a very long period of time. It is commonly sold in quite small starter sizes (quart size pots) for this exact purpose of container planting. And grown in a container it would take even longer (and with routine potting up) to ever achieve that projected mature size.

It may be different in your neck of the woods but growing plants in containers - ALL kinds of plants - is a very common practice here. There are some who devote an entire business practice to container design.....and not just seasonal container design. Maybe it has to do with our rather urban setting and the fact that many folks don't have any land......or very much land.......in which to plant directly. Lots of condos, townhomes, zero lot line houses and even floating homes, all of which make inground gardening difficult, if not impossible.

And contrary to what you might think - these plants thrive for many years under these conditions. I grow my entire collection of both conifers and Japanese maples in containers and have done so for years. The only consideration for long term container growth for any kind of hardy plant in my and cadence's location is the quality of the potting soil and attention to watering and routine fertilization. And the need for some rather infrequent root pruning.

Expand your outlook and broaden your horizons :-) Not everyone gardens in acres of sandy Michigan prairie!!

but gal.. all i was trying to tell her.. was that her little urns.. arent going to hold an 8 foot tree ...

then you said: It is commonly sold in quite small starter sizes (quart size pots) for this exact purpose of container planting

and i admitted i suspected such ...

and no.. i have no real interest in learning .. in depth about pots ... they are a PITB up here.. winter storage and all.. all the power to those who like the challenge .. i am just not up for it ...

anyway.. GO VERTICAL ... and enjoy whatever comes of it all ...

I dug up one of mine approximately two weeks ago and transplanted it. It is growing new leaves already and is looking healthy and didn't go through too much shock. I'm thinking that if yours are "sad" looking, you may wind up going back to return them again.
It could simply be as Kevin said that it is because they are in pots. Did you pay full price?

Good luck!

Thanks, Judy!
Yep, I paid full price, but they looked fine when I bought them. I planted most of them, but replaced the 3 worst looking ones since my last post. I have 2 left to plant, I'm shooting for tonight. Most of the ones I've planted are looking fine, but two are a little wilty. I'm afraid to overwater them, how often should I water them? Oh and are the roots supposed to be mostly brown?

Thanks again for any help!

I started Echinacea PWWB from seed last year, and they bloomed this year. I would agree with others, they are a compact and bushy Ech. with lots of blooms.

I reserve further judgement however - my Echinacea didn't exactly have a banner year. Almost all the plants were transplanted to new locations this past Spring. Partly to fill in where the voles had wiped out the original plants, partly to plant out a new bed. They are still getting established.

I started them from seed last year, they bloomed the first year and were gorgeous, unfortunately this year they were hit with aster yellows and were yanked. Guess I'll be starting some more next year.

I've never met a Sedum I didn't like, although some need a special spot so they don't over-run an area, like dragon's blood. I left them all behind in OH, but I still remember Lida Kense and Bertram Anderson, both with beautiful bluish foliage and pretty pink flower heads.

I agree with everyone here...there are only a few Sedums I don't care fore. My fave, at the moment is 'Matrona'...those bronze leaves and deep red stems are just gorgeous...especially when backlit. Of the most prostrate forms, 'Angelina' is a winner...and so welcome in winter. 'Blue Spruce' is really nice...and recently, I found a few (to me) variety called 'Blue Carpet', which is the most wonderful shade of blue/purple. Just planted 'Hab Gray', as I was intrigued by the yellow blooms...can't wait to see how it does!
Oh, here's a post I did on 'Matrona' a while ago!

Here is a link that might be useful: Post on 'Matrona'

Thanks! Wasn't sure if it was common for this to happen or not.

They get huge fast! It must be the perspective but that Coral one shown above is almost 4' wide.

The red is fading a bit on this one, but still nice!

They are both very pretty! I will have to look out for those mammoth mums.

Yes in my experience seedlings can have a lot of genetic variation - just like kids can from their parents and siblings. It makes things interesting, although if you're looking for more uniformity then clones work better.

Campanula UK Z8

If you have H.orientalis, it is unlikely that groundcover beneath it is going to be an issue since mine make dense evergreen mounds of rather good foliage which persist all year,ting cut back completly (and briefly) as soon as the new blooms appear. For a very short time, just the stalks and flowers are visible then the new growth roars in and it is totally dark under the hellebores again. Same with many ferns -the leaves tend to recurve back to the soil level.You could add height though, maybe growing something much lighter through the hellebores (thalictrum, grasses, one of the taller anemones) to hover above.

Kevin, I agree that it won't hurt anything. But peat moss that constitutes the bulk of many potting soils err...media (sorry Ken)...is not compatible with clay because it holds water when wet, which is the last thing you need clay soil to do. It also adds no nutritive value to the soil. But yeah, I've dumped it out in my garden with no qualms because it isn't enough to matter.

Just don't dump it in the same place year after year or you will get a soil borne disease like someone I know did and it won't grow anything,

Thank you all for the info!

Well...I only planted once and I didn't get to see the blooms even once because we moved. Then the new owner took absolutely everything out and put rocks because she had a dog. :( I don't want that to happen again. :) But I get what you mean.

I'll try to be optimistic but still realistic. ;)

And I did go to Hallsons. They were really nice there and had a lot of nice hostas. Thank you again for that.

I agree Sunny that AA is extra noticeable this time of year as many other plants have finished flowering but don't sell some of the coreopsis short in this regard. Here is a picture I took just today of my 2 year old "Cosmic Eye" coreopsis. It has been flowering as long as has AA.

vivian_2010 (IL Zone 5a)

I have 1 Arizona Sun for the last 5 years and it came back every year, on mended clay soil. I do not do anything special prior to fall and winter time. However, I do notice that the new plant emerges pretty later in spring. Actually every spring I thought I had lost it but it came back, first as very tiny little plant, most likely from seeds. So if you do not see them emerge next year, be a little patient give them a little more time to be sure. This spring I almost planted something over it as I was not sure if it is still alive or not. Tt was as tiny as my finger nail but grew to be a regular plant in no time.

Since you have several Arizonan Apricot, you can experiment different things and see how they work. But please do post back with your results next year so we can all learn.

Best of luck,
Vivian

According to "The Well- Tended Perennial Garden" they should be divided about every 4 years or as needed either in spring or after bloom in fall. In zone 5 I think I'd wait and divide in spring.
