When beginning to think about permanent edible landscape design and forest gardening, taking in the general concepts of Permaculture can help tremendously.
An edible forest can feature a number of natural layers. Fruit and nut bearing trees can create a canopy, dwarf trees shrubs and vines can create a natural under layer and be followed by low growing plants and ground cover. Plants that enjoy similar conditions and/or have a symbiotic relationship with one another are often arranged near one another in guilds. Careful consideration to conditions such as soil and exposure to sun as well as guild mates is wise given the significant investment and permanence involved in planting new trees, bushes and perennial flowers.

Another interesting option is Haskap berries - which might be the next new superfood – but most people haven't heard of them yet. We found a supplier online that will deliver to the door here
That's because the berries, which are higher in antioxidants than blueberries, have traditionally been found only sporadically in the wild across Canada, growing mostly on the edge of wetlands. Until that is Bob Bors of the University of Saskatchewan got involved - and he's been very selective of varieties from their native habitat of northern Japan and Russia.
The plants are being grown in most provinces now, with more than two million sold, "which is pretty big for any plant breeding program," Bors says.
Haskap, meaning 'little present on the end of a branch,' is the name given by the Japanese. Other names include edible honeysuckle, blue honeysuckle and honeyberry. "It's got this raspberry, wild blueberry sort of undertone, and then all of a sudden there's that Honeycrisp [apple]," Bosse says from Pictou County, N.S. "It's got that real funky flavour profile," which he likens to bumbleberry, or mixed-berry pie."
Some people say the berries – which are dark blue, oval or cylindrical, and about 2.5 centimetres long – have a hint of elderberry, black currant or grape, and a tartness that makes them great for baking a pie with.
