Flower care for flower deliveries to Castlecrag

If your flowers are arranged in florist’s foam, top up the water daily, taking care not to overfill.

If you have received cut flowers, trim the stems diagonally about 2cm from the base prior to placing in clean water. Take special care to remove all leaves that will be underwater, as they contain bacteria that may quickly proliferate and spoil the water.

Position your flowers away from draughts, direct heat and/or sunlight. Do not place them on heat generating appliances such as TVs and microwaves.

As some flowers will last longer than others, carefully remove spent blooms, especially if other flowers in your display are still alive.

Castlecrag is a residential suburb located eight kilometres north of Sydney's central business district, on the Lower North Shore. The suburb is partially surrounded by Middle Harbour, with it eastern portion sandwiched between Fig Tree Cove and Sailors Bay. Castlecrag is notable for having been planned by Walter Burley Griffin and his wife Marion Mahony Griffin.

The suburb's outlay was originally designed by Walter Burley Griffin (best known as the architect who designed Canberra) and his wife Marion Mahony Griffin from 1925 onwards. They named the suburb after a towering rock crag that overlooks Middle Harbour. Many of Castlecrag's original homes were designed in the Arts and Crafts style, utilising natural stone to blend them into their surrounding environment. The suburb is notable as an early example of 20th century communal and community planning and living. 

Points of Interest

Castlecrag is home to a significant selection of heritage-listed private residences including Buhrich House II, The Glass House (Castlecrag), Duncan House (Castlecrag) and Fishwick House, with the latter two both designed by Walter Burley Griffin. The suburb enjoys a leafy streetscape throughout and a variety of green spaces, many of which front onto Middle Harbour, such as Beverley Blacklock Reserve, Burrabru Reserve and Sailors Bay Park.
