They don't look like succulents...but I never grew any from the seeds :)

What were they supposed to be? (names of succulents?)

Kateh, I'm sorry to rain on your parade but I have to agree with Rina here. Your seedlings do not look like succulents. Maybe checking with the source of your supplier will help.

Believe it or not, succulents have very slow growth. They take about at least 1-2 years to reach a decent maturity size.

Could be weeds...one looks like a clover, the first one - maybe??? - a marigold (if it is, at least you will have some flowering annuals).

I wonder if your soil (or your seed pack, for that matter) could have weed seeds. One does look like a clover.

Bernard! Those are ADORABLE!

Lol dammit. Thanks anyway guys

Let's hope that clover soon grows four leaves!.....that will bring you 'good luck' with your next purchase of true succulent seeds as I agree that these are definitely not succs at all! Maybe the mix was contaminated with weeds, maybe there were succ seeds in the packet but due to the peaty/organic mix you used they could have rotted, or, maybe the fact that the mix is so unevenly levelled the often tiny succ seeds have got buried too deeply to germinate? Lots if maybes here.

The first one looks like some type of geranium ( if you rub the leaves together and it sends out a fragrance it is) Or it could be a form of mint it's to small to tell for certain as it might be a wide range of other fat type plants ( time will tell if no fragrance) at that size it covers a wide range of other plants. ( IE Ibervillea, Impatients, ect)

The bottom one is an Oxalis carnosa ( maybe, and is if you see small bright yellow flowering) they self pollinate then drop at short range the seed will sometimes spit for wider self sowing often they drop by moving or brushing up against it. Like weeds they are pretty easy to grow and can often spread into some to neighboring pots where you might not want them to grow With easy to handle control they shouldn't become overly invasive. I avg apx sixteen to twenty new seed starters per year per pot and toss most of them outside where they die in the cold winter here

With a very wide diversity of SA plants technically ( like Sanseveria) neither of them in your pics are a 'true succulent', but they can be a lot of fun to pot cultivate while being treated as a succulent, In time ( one year later as seen in pic) some will build caudex for a touch of added enjoyment.

In defense of your plants not being weeds ( per say) there are some Kalanchoe that also grow as quickly and as easily as weeds and folks will often rave with positivist comments to the cultivating of them.
