Foxtail Fern, Protasparagus densiflorus 'Myersii'
There are several varieties of the Protasparagus genus but foxtail is the most attractive one.  The plumes give give a soft cloud like appearance.
Foxtail fern can be planted in trios for an eclectic effect.  I used this arrangement for the entry of a relatives house.
