One of many causes I actually take pleasure in having fruit bushes is that they’re perennials: they provide again lots for comparatively little effort. You may get the identical advantages from perennial greens.
The commonest perennial greens for our space are artichokes, asparagus and bunching onions (scallions). Others which might be extremely suited to our Napa Valley local weather are cardoon (a relative of artichokes), tree collards (often known as tree kale or strolling stick kale), strolling onions (additionally known as Egyptian onions) and nopales (prickly pear cactus pads).
Extra choices embrace sunchokes (Jerusalem artichokes), perennial arugula (warning: it self-seeds readily) and miner’s lettuce (claytonia). In our local weather, miner’s lettuce acts like a self-seeding annual, however it’s a perennial in areas the place it receives adequate moisture.
As well as, you’ll be able to “perennialize” common kale, garlic (for inexperienced garlic) and, to some extent, Swiss chard and broccoli. To begin treating common kale as a perennial, merely reduce it again to a couple inches of the stalk when it begins to look drained and it’ll resprout. You are able to do the identical with broccoli. You received’t get one other giant head, however you’ll refresh the plant and get extra small facet shoots.
In my yard, Swiss chard readily self-seeds, so there’s all the time some chard rising wherever I water usually. If it’s not in the way in which, I let it develop. Should you plant garlic and don’t harvest the bulb, it is going to sprout as a cluster of inexperienced garlic the next rising season and proceed to create bulbs underground. Ultimately, as with flower bulbs, you’ll have to dig it up and divide it. Maintain a number of the greatest bulbs and replant some cloves for extra inexperienced garlic.
