I am bamboozled what I am growing

v Hi, I would be grateful if somebody could tell me the names of the plants I am growing. Several years ago I bought 2 plants on Ebay. I planted them in big pots. They are already about 6' tall and it seems to me they are ready to flower for the first time this autumn. As far as I remember when in blossom they should look like yellow mimosa but their leaves are different. Unfortunately I forgot to write down their names and I have failed to find them on Google.
Then a year ago I planted seeds but again I can't remember the names of the plants.
Only 4 survived and they are already 7" - 10" tall.
Now I understand how important to know the names of the plants to be able to grow them successfully.
Could anyone help me to identify my plants? Thanks in advance.

 

The one in the garden looks like Cytisus (broom). The other one, if not a fern, could well be an Acacia.

 

First one could be an Acacia but it looks too rigid or even a needle leaved Grevillea, if not, I don't know and the second one looks like a Jacaranda.

 

I'd go with acacia and jacaranda.
Pretty sure on the jacaranda not so sure on the acacia, did it have different shaped leaves when small?

 

Acacias bud up now for late winter/early spring so it could be one, perhaps A. rigens?

 

Would it be Acacia retinoides? The leaves look right and they flower in the summer.

 

The Jacaranda stands no chance outside during winter in the UK.
I'd also be a bit wary about the Acacia, it dont look that hardy to me.

 

Thank you all for the replies. I agree that the second plant looks like Jacaranda mimosifolia.
The first plant could be acacia but I am not sure if it is rigens or retinoides because, it seems to me, the leaves are not the same. The leaves are like pine needles but very soft about 2" long. I hope the plant will flower very soon and it will be easier to identify it. I will add photos when and if it happens.

 

I think, with your help I have managed to identify the first plant in my garden. I believe it is Acacia Boormanii. Thank you very much.
