NEW ZEALAND DAISY-BUSH, Okaria Haastii. 



Gardens, shrubberies, rockeries. July— September. This is the hardiest 



of the Olearias, and will do well as far north as the Midland counties. In 



smoky districts it does better than most evergreens, and is also an excellent 



seaside shrub. It makes a dense Box-like bush, well suited for forming a 



hedge, and may then be pruned in early spring or after flowering. In late 



summer it is almost completely covered with little Aster-like blossoms.
