Perennial foods

Over the years I have worked to establish more perennial food plants on our property. They typically cost a little more upfront but having low-maintenance, recurring sources of food is great. In the process of writing this post, I realized we have over forty different perennial foods growing on our property - a mix of naturally occurring and purposefully introduced. 

I have integrated these perennials plants in various places on the property, creating a bit of an edible landscape; but I also have a few dedicated perennial beds in a section of our property. I keep these beds separate from my main garden so that they don't interfere with crop rotation. Before I switched to a no-till approach, it was a also a concern that they would get in the way of rototilling. 

I'll provide a summary of the perennial foods we grow, in hopes that it will give you ideas if you live in a similar zone. Even though we live in zone 5, I tend to favor perennials that are rustic to zone 3, to ensure they are very rustic and survive our winters. 

Trees:

• Apple trees - I planted a few specific apple trees (honeycrisp, empire, and a sweet yellow variety); we also have a variety of wild apple and crabapple trees planted by animals in the forest. (two or more compatible apple trees are needed for cross-pollination)
• Pear tree - I planted four pear trees, which should be two cross-pollinating pairs. They haven't produced yet but I think they will this year.
• Plum tree - I only have one plum tree, they are self-fertile so they don't need a companion. It's new and hasn't produced yet.
• Hazelnut trees (bush) - I have eight hazelnut trees, I planted them this year. I got them from Meadowlark Rise Farms, local to us. They plant a variety of nut trees, but it seems like hazelnuts are doing the best in our area.'
• Sour cherries (bush) - This one spreads! It is beautiful when it flowers, and I use the cherries to make ice cream, Turkish cherry jam, and chocolate cherry jam / ice cream topping

Berries and other small fruits:

• Honeyberries (Haskap) - these do amazing here, but they need to be covered by a net or the birds get them all. They are a great early crop. 
• Gooseberries - new this year
• Strawberries - I chose everbearing plants which means that they produce throughout the season, instead of one big batch. They are great for snacking whenever we pass in front of the patch, conveniently located between the house and the workshop.
• Saskatoon berries - new this year
• Concord grapes - for eating fresh and for juice
• Artic kiwi - new this year

Edible flowers:

• Daylilies - the flowers are edible. They are a nice snack or a nice garnish on salads. Be sure not to eat lilies though.
• Hostas - the shoots can be cooked and eaten
• Lilac -  good for garnish or for making flavoured simple syrup , I can it and use it to make lilac lemonade or seltzer water
• Sunchokes -  the tubers are delicious. We especially like them fermented (which also takes away the gassiness that some people experience with sunchokes)
• Sunflowers - for seeds

Herbs:

• Rosemary - doesn't always come back, depending on winter conditions
• Lavender - doesn't always come back, depending on winter conditions
• Sage - doesn't always come back, depending on winter conditions
• Mint - invasive, be careful where you plant it
• Oregano - invasive, be careful where you plant it
• Thyme
• Chamomile
• Chives

Others:

• Rhubarb
• Horseradish - harvested for the root. Can spread.
• Asparagus
• Amaranth - not really a perennial, but it reseeds itself generously 

Naturally occurring perennials (foraging - more details here)

• Raspberries
• Fiddleheads
• Daylilies
• Sumac
• Sugar maple
• Cedar
• Stinging Nettle
• Mushrooms - for example shaggy mane. Still learning about these
• Wild grapes
• Crabapples
• Wild chamomile

Failures - things I might try again:

• Sea buckthorn - got swallowed up by weeds, will need to try again
• Blueberries - I've tried these several times but they never survived, I'm not sure why
