How to Enable Flowering and ID

I bought this plant at the Philadelphia Flower Show in the 90's. It flowered once since then. The flowers were small and yellow and they lay close to the stem. This plant has a very lively blue green color and seems very content, 2-3 years in that pot.

 

looks to be some kind of euphorbia.

 

Thanks Jocelyn your lead was helpful. I found out that it is Euphobia Aeruginosa.

 

glad to help get you in the right direction. it's a particularly interesting specimen! i've been getting interested in euphorbia's lately and i really like those that have the blue skin - SO different!
