Hi Natalia,

Crassula argentea is a synonym of Crassula ovata, AKA the common jade/Jade plant.

That first plant could be Crassula ovata 'Crosby's Compact', but it will need to get older for you to be sure - it does look it, but perhaps before you change tags you'll get confirmation here.

The last two do look like they're named - Crassula ovata and Crassula ovata 'Gollum'. Please note how botanical names are written - genus name capitalized, species name lower case and any cultivar (cultivated variety), such as your two above, the word or words in the name should all be capitalized.

The plants look like they're in good condition and wanting to grow - are you going to introduce them to more sun?

I agree with the identifications.
Jeff's correct about the "argentea" synonym.
I just copied this from Peter Lapshin's site:
Crassula ovata v. minor cv. Crosby's Compact

The first looks to be a compact, as does the cutting from a friend.

Regular ovata and 'Gollum' are both correct.
Given the variation of leaves on the 'Gollum,' you might even label it monstrose.

cactusmcharris and Josh, thanks for helping me id the jades

and how to write their botanical names correctly.

cactusmcharris, all of those jades have been growing

outside from the past 2 weeks. They look healthy and have

no more brown leaves on the variegated jade (old post). I'm

going to introduce the Crosby's Compact into more sun.

Thanks :)

The Crassula ovata 'Gollum' looks perfect to me and not monstrose. But you can call it any thing you please unless it has been published differently. It is a sport, and it looks like it doesn't have a speck of 'Crassula 'Hobbit' in it. It is rare now to find one that perfect. The 'Jade' above are just regular 'Jade' not necessarly Crosby had anything to do with it at all, except tag a name on in order to sell it. If it wasn't published correctly with a Latin description you may change the name. C. agentea is known to have a much smaller leaf, I believe that is just a another different form of C. ovata I have several of those with different names depending who I purchased them from and they are all syn. with Crassula ovata. Look in Gordon Rowley's book, regards to all Norma

There are quite a few slender leaves - similar to 'Skinny Fingers' - on the 'Gollum,'
which is known for its trumpeted (or flared) cup-tipped leaves. Given the strong mix
of leaf-types on this one plant, I'd be comfortable calling it monstrose.
Most of my 'Gollum' plants exhibit the same characteristics.

I'd be surprised if those first few Jades aren't compact.

Regarding the gollum/ hobbit leaves showing up on a single plant. I have seen a large hobbit recently that has both hobbit and crosby compact leaves in 1 plant. There was one branch from the middle of the large hobbit that has regular jade leaves, small ones like a crosby compact, and leaves were very rounded.
I tried to take a picture with my cell phone but it didn't turn out that great.
Any one else seen something similar?

Yes, that's how these sports are usually discovered.

I don't know how accurate the following passage is, but I've seen it repeated several times:

"A Hobbit Jade, for example, is a monstrose growth form that originally appeared on a Crosby's Compact Jade. The Crosby's Compact Jade or Mini Ming Jade is a small leaf monstrose, which was first found growing off a Regular Jade."

Thanks Josh for the explaination.
