Hello Joe Just wanted to let you know that I found the name of the plant. You were right it was in fact a euphorbia. Euphorbia bougheyi Thanks for putting me on the right track Joy

1st is a Breynia, 2nd is some kind of variegated Poliscias / Aralia. 3rd is variegated Dizzygotheca elegantissima or False Aralia. I don't know the 4th, maybe a Ficus of some kind. Nice whatever it is. It's great that you've got them in what looks like somewhat fast draining mix, but I might have left them in plastic pots, so they don't dry out as fast. Great looking group, nice haul.

Sarcococca would not survive zone 5/6 or if it did, would never recover good foliage by September, unless protected. There are precious few cultivars of Prunus laurocerasus that can survive zone 5/6 like 'Otto Luyken.' Certainly it's not 'Mount Vernon.' Many of the larger-leaved laurocersus do not even do well here in zone 7 East Coast. So given its hardiness, and the fact that 'Otto Luyken' is the most available and commonly grown evergreen Prunus shrub in the Mid-Atlantic, it's extremely likely this is 'Otto Luyken'.

The first one is a Peperomia; I don't know which, but you can poke around over at peperomia.net and maybe find it. The second is Elatostema repens - which has been known as Pellionia repens until recently.
