They were Y Rostrata 'blue saffarire'
I bought 2 three gallon potted for $12.00 (us) each.
They had 5 gallon potted for $24 (us) and they were much larger and branching already or were several in the pot.
I like the columnar look but bigger would have been better.
I agree with Jim , Dont give them away.
$200 (us) isnt out of the question either for a nice plant like that.
Im just hoping I can pull these off and make a go with them.
Not sure where you live in the UK but if you live near London , I would call around to some in the trade and see if you could get a better price.
The people of the UK love plants and that sounds like a good one !
