Lynn, Why not edit your post and add links to these sites? I think SMG goes under SMG Succulents and Edelweiss is Edelweiss Perennials

Good thing you are here twit. On my way.

All better. : )

Thank you, pretty lady

You don't wear glasses do you?
Am I missing any that should be on the list?

Ok, as a newby and not really knowing where to start. I will start here. I must be hooked as I have spent most of the day on web sites helping me understand what the differences are in Semps, Joviibara, sedum & et al.

I left my family history and genealogy to become a bit more conversant with the little dears. Now I am wondering about the different ways of propagating and gardening them for greatest success. I have a vertical container garden but am thinking about some other possibilities with very very limited space.

What are pros and cons to beds, rock gardens, crevices (why crevice garden?) and regular container gardens?

Thanks,
Marilyn

Hi Marilyn. So sorry if I disrupted your genealogy work. But we really must spend time outdoors, and what better way to do that?
I see you are gathering quite a collection of succulents.

Semps, sedum and Jovibarba are all succulents belonging to the Crassulaceae family. Semps and Jovibarba are closely related, but have different growing habits.

Semps reproduce offsets on stolons with the offsets rooting while still attached to the parent rosette.
Sempervivum 'Ford's Spring'


Jovibarba have two different ways of reproducing.
The roller type produce offsets on very brittle, short stolons that break away from the parent rosette, causing the offset to roll away from the parent before rooting. This is very interesting to observe. They can even settle on top of their little heads, and some how right themselves to form roots. See how the tiny offsets are rolling away from the parent?
Jovibarba f/Col De Turini


Jovibarba heuffelii form their new rosettes from the parent rosette's crown/root. The only way to have new, separate plants from this type is to surgically divide them through the crown and root, using a clean sharp knife. You must have a healthy section of root attached to each rosette when doing this procedure.
These are all growing from the same crown/root system.

Aren't you lucky to have Tabby, picklepuff and t1nerbelle living close by. They are all a wealth of knowledge when it comes to growing succulents in your area of the United States.
I sure had a great time nursery hopping with you while we were visiting. Wish we lived closer.

Sister, Just wanted to add, from a technical point of view, that many professionals consider that Jovibarba should be actually Sempervivum as well. The various Jovibarba species are considered subspecies of Sempervivum. The professionals that work with stuff, from time to time, change their opinions as knowledge increases. Jovibarba have been Sempervivum before and this has changed.

So why do we need to know this? Well, you may come across a name of a Jovibarba that is called a Sempervivum or the opposite. We're just hobbyists, so we go with what we know.

Thank you twit. Some times it gets rather confusing. Even in the sedum categories.

Thanks for all your very helpful info. I will hope to just keep learning. I went to Denver Botanic Gardends again yesterday and enjoyed looking at all the new plants in bloom. Wish you could see them. A lot of Iris in bloom now. My camera does not do them justice or I would post something.

What kind of camera do you have sister? Surely you can make it work? Or are you just trying to get me back to Denver?

CDsSister, if you went to DBG, then you are in the Denver area? Some of us in the Denver area are quite willing to give away sempervivum.

As to the advantages of the different types of gardens - it depends on what you like and what space you have. I find the sempervivum, jovibarba, etc. do better in the ground than in pots, but I have many in pots that do pretty good. The nice thing about pots is you can move them around. It looks like you have a very nice hypertufa pot in your vertical garden. Sempervivum do very well in hypertufa pots.

I like the look of rock gardens, but I run out of space for the rocks so just end up with rockless gardens with rock garden plants.

t1nerbelle (Audrey) came over today and we went over to Timberline Gardens in Arvada. . That place is so awesome for semp and sedum lovers.

Tabby, you know CDsSister. : )
She is my SIL.

She got the hypertufa pot when we all went to the sale at the Denver Botanical Gardens.

Oh I wish I could have been there with you. I fell in love with that nursery.

I may have to get back to Timberline and see if I can get one of the Grigg's surprise... they look interesting.

My camera is a little Olympus and it has a micro mode but have not figured it out yet.

Sure, Lynn, You can come on back. I laughed and said not only do I have to learn about Semps etc but I have to learn about photography... I wonder if there is enough room in my brain to learn all these new things.

Tabby, I am in Greenwood Village, and I remember how wonderful your gardens were, when I visited with Cliff and Lynn. I bet they are beginning to really fill in by now.

Marilyn

First thing you have to do Sis, is to throw out some of the old stuff stored in your brain. That will leave plenty of room to learn about photography and succulents.

If a cluttered desk is a sign of a cluttered mind, then what is any empty desk?? Why its obviously a good place to work!

Lynn, as always, makes good sense. Just don't forget how to drive or type or...

Wow twit, you make me sound so wise.
To bad she already knows me.

Oh you are all so wise.....in the way of plants

I am off to Timberline this afternoon, hope they have some of those banana surprises

I am also looking for rocks just to add a bit of interest to my river rock around my townhouse.

I'll let you know if I find fun things to add to my garden, but first I am going out there and catalog what I do have.

Wish me luck,
Marilyn

Good luck Sis. Wish I was going with you. I could spend all day at that place.
Can't wait to see photos of your new plant babies. Hope they have one of those Banana Surprises waiting for you.
