Is Argula Cut and Come Again
Arugula (also known as rocket or roquette) holds a special place in the pantheon of leafy greens, offering a unique flavor that no other can provide. And growing them in your garden, in the ground, container, or even on your windowsill is easy as tin be.
But do you have to keep replanting them every yr, or will your arugula plants go along coming back? Whether or not arugula will come back depends on several factors (and whether you consider self-reseeding every bit coming back) which are discussed below. So, make yourself a cup and let's talk 'rugula.
Does Arugula Come Back Every Year?
Yes, however, it depends on the type of arugula. Standard garden arugula is an annual which won't grow dorsum the next year, but it can easily reseed itself, sprouting new arugula plants the post-obit year. Wild arugula (Diplotaxis tenuifolia) is a perennial which can survive moderate frosts and grow back every year.
Because of this, you tin easily keep a "perennial" arugula bed or container in your garden, letting arugula reseed every year. Arugula seeds tin can ofttimes survive the wintertime and germinate in the spring when the ground thaws. Arugula itself can survive frosts down to 22°F (-6°C) , with some hardier varieties lasting longer. Still, even if it survives the winter, mutual arugula reaches the cease of its life cycle after flowering; wild arugula tin go along coming back every year while also spreading seeds.
Do I Need to Overwinter My Arugula?
Y'all really don't need to overwinter arugula in nearly climates. I've had some wild arugula survive winters with temperatures sometimes plunging downwardly to -4°F (-20°C) and self-reseeded garden arugula seeds still sprout the following spring.
However, if you do live somewhere where those temperatures are normal, a few inches of mulch (leaf mulch, straw, or small wood chips) over your arugula bed should offer good protection. Just remember to gently sparse out the mulch the following spring. If container gardening, you lot can even keep it in an unheated garage to overwinter. But if you're well beneath the Chill Circle, y'all likely won't need to do it.
Does Arugula Reseed Itself? Does Arugula Spread in the Garden?
Both regular garden arugula and wild arugula can and do reseed themselves, and will spread easily in your garden if you let them flower and go to seed.
Is Arugula an Annual or Perennial?
Mutual garden arugula is an annual, whereas wild arugula, a completely different species in the same family, is a perennial. Since both are ordinarily cultivated (and both easily reseed) this has led to confusion.
Despite garden arugula surviving frosts, it's notwithstanding an annual, and then subsequently information technology flowers and produces its seeds, the institute volition die off. Wild arugula also produces seeds (quite prolifically) simply will proceed growing and the side by side jump it will come up back, frequently forming a large rosette, then later growing into a bushy arugula establish.
Differences Betwixt Mutual Garden Arugula and Wild Arugula
Common garden arugula ( Eruca vesicaria , sometimes classified equally E. sativa ) and wild arugula ( Diplotaxis tenuifolia ) have similar season profiles simply grow differently. Garden arugula usually has large-lobed leaves, is an annual, and has white flowers. Wild arugula has more than serrated leaves, is a perennial, and has yellow flowers. Wild arugula is also more heat resistant (bolts more slowly).
At first glance, yous tin often tell the departure between garden arugula and wild arugula varieties. Common arugula has large, lobed leaves, whereas wild arugula has serrated (sometimes extremely serrated) leaves, akin to oak leaves. When they commodities, it's fifty-fifty easier to place them, since all garden arugula varieties produce white flowers with four long petals, while wild arugula varieties produce smaller yellowish flowers , similar to mustard.
These two types of arugula are unlike species but both are part of the Brassicaceae family, which is a large family of plants including broccoli, kale, cabbage, radishes, mustards, and horseradish.
If y'all've grown these other Brassicaceae vegetables before, you likely accept noticed that a lot of them bolt very easily in hot weather — arugula is no exception. However, wild arugula tends to deal with hot weather better and can resist bolting (producing a blossom stalk), frequently weeks or sometimes more than a month longer than mutual garden arugula. (Gardener'due south note: As I'grand writing this, after less than a calendar week of unusually hot weather condition, almost all my Astro arugula has bolted with many flowers opened up, while nearly of my Wild Rocket arugula nevertheless hasn't bolted, and only a few merely accept their first buds.)
What Happens When Arugula Bolts?
Arugula bolts in hot weather, regardless of the time of year. When arugula bolts, yous volition discover new leaves growing smaller and being more spaced apart as the institute starts growing more vertically, and if you lot await carefully, you will see the tiny buds forming on the tip.
Yous will often notice on garden arugula varieties that the stalk and fifty-fifty the leaves volition start getting hairy, the stem volition go tougher, and the leaves volition get spicier and also more bitter.
When wild arugula bolts, the new leaves also become smaller. All the same, wild arugula doesn't get nearly as biting when it bolts, and for people who beloved the taste of arugula, information technology tastes almost equally proficient after bolting. The leaves also remain tender and don't get hairy.
The buds, flowers, and even the young, tender seed pods of all arugula varieties are edible, too.
Which Is Improve: Common Garden Arugula or Wild Arugula?
It might seem like wild arugula is better in every manner — information technology'south more commodities/estrus resistant and it'southward a perennial. However, there are some drawbacks to wild arugula.
- Wild arugula has a slightly dissimilar flavor profile than mutual garden arugula. Depending on the growing conditions, it tin can be a bit spicier than the arugula you're used to. Nonetheless, the flavor doesn't modify as much after bolting.
- Wild arugula tends to have smaller leaves.
- Garden arugula germinates much faster and grows faster than wild arugula, reaching maturity sometimes weeks earlier. Some garden arugula varieties, similar Astro , can reach maturity within xxx days (sooner for infant arugula) while the super commodities-resistant Wild Rocket will take 50 days, not including the extra time for formation.
So, if you lot prefer large, luscious arugula leaves and quick harvests, grow garden arugula. If you don't heed waiting longer before you lot tin harvest and you similar the flavour of wild arugula, grow that. Or, if you're an arugula aficionado, do what I do and grow both!
