Senna/Cassia bicapsularis

I recently found some Senna/Cassia bicapsularis seeds that I was sent a few years ago. As the first one is germinating already (just four days) I got to wondering if anyone on here has grown this and had any luck with it. I suspect that it may be a bit of a big ask here in the UK.

Any tips?

 

No knowledge, I am afraid LongK - but it makes a fine looking tree.

 

Not had much luck with Cassia in general, I find most too tender and big.
But then I've only tried a couple

 

In the walled garden next to the Plant Centre here I work( occasionally) there are two large Cassias about 15ft high and just setting seed. I am not sure which Cassia it is but I will look for seed pods next week when I am there. They are some years old but get protection from the high walls so I am not sure how well they will do elsewhere.
I imagine they would need to have some ripe wood on them before planting out but maybe ok in a pot for a couple of years first.

 

Thanks guys! The seed was free so it's worth a punt.

 

I doubt that the Cassia I grow here is bicapsularis but will put a few ounces of seed in the swap parcel as it goes by, anyway, for anyone who wants to try a relatively hardy species. It has survived -17C in the open with no problems!

 

Would you have a photo of it?

 

The best I can do is this photo of the general area, longk. It's about 1.2m high with the usual yellow pea-flowers (18mm) in June / July.


The one I really want to grow is Cassia javanica

 

I can see why!

 

Isn't it pretty? I've had a dozen seedlings but they don't like being transplanted at all......ah well onward and upward

 

When you say being transplanted do you mean being pricked out, or maybe being potted up?

 

The first seedlings were pricked out (carefully) from 3" pots and resented it.
Subsequent seedlings arrived in the soil of the polytunnel where I chuck my old sowings....they didn't like being moved, either! Grrrrrrr.

 

@noisette47 - with the Fabaceae family I'm having far more luck on cotton wool in placcy bags. Zero losses so far when lifting to pot up.

 

Thanks for the tip! I did try Ziplocks last year for all my seeds but on balance, lost a lot...probably due to sciarid flies afterwards. I'm going to try Jiffies this year. No danger of root disturbance there....
As an aside, did you know that Geranium madarense needs to germinate in cold, wet compost? It's news to me Wet, maybe, but cold??? At least it's in exactly the right place here

 

Madeiran cold or Northern European cold though?
