Saving Seeds: Lettuce and Arugula

How to go about saving seeds from lettuce and arugula plants.

Seeds from lettuce plant

Gardening in Florida is still a new thing for me. Even though I have lived here in Florida for many years, I never had a vegetable garden until recently. Typical tropical plants and flowers I understand, but I never had time to try to grow crops like lettuce and arugula.

Finally, I think I am beginning to get the hang of it. I realize I can’t grow what I used to grow in New Hampshire’s short summers. I’ve tried to grow cucumbers and squash without luck. Maybe the seeds were bad, I don’t know. This is such a different climate. Everything is backwards as far as planting seasons.

Lettuce and arugula (and kale) like cooler temps. I planted those seeds in Fall. They have done well over the winter months, even with Christmas temperatures in the 20’s.

Now it’s time to save the seeds. My plants began from a company called Seeds of Change. I bought the seeds at my local Home Depot. The seeds are certified organic, and nearly everything I planted has done very well. I absolutely recommend this brand of seeds.

Collecting Seeds From Lettuce

The lettuce was planted in with some peppers so I didn’t have much space. I wasn’t too hopeful for it to do well. But it did! I never ate any because it was bitter, but I have collected the seeds to try again next season. I’ll have to save space for a lettuce garden.

Now that it is March, the hot weather is on the way, so I want to let my greens go to seed so I can collect those seeds. I’ll save them inside the house to plant in the Fall.

I’ve never had luck growing lettuce so this was a complete surprise. My lettuce was a mix, so I am not sure which types these were. But one of the plants sent off this long shoot which ended up hanging over the side of the garden bed.

The green leaves ended up dying back and the stems became full of seed pods!

The spiky, thin stems each held dried pods holding little black seeds! I have collected a bunch of them.

I’ve also collected seeds from a flowering lettuce stem that produced dandelion type heads. Once the weather gets cool again, I will plant them and see what happens.

Collecting Arugula Seeds

I’m sorry to say that I am unfamiliar with arugula. I tried some of the leaves, which are peppery and really good, but without something to mix them with, I rarely ate them.

Now I am letting the flowers grow to get the seeds. I didn’t realize that the stems hold the pods that will dry out and give me seeds, until I noticed them!

I’ve noticed honey bees and many other insects on the arugula flowers. Even if you don’t use your greens or other herbs and vegetables, let them grow and create flowers to help the insects.

How to Save Seeds

In general, plants will “go to seed” once the growing season is done. Also called “bolting” it means the energy of the plant goes into making seeds to continue the vegetable / herb.

Left alone, the seeds will dry, fall to the ground, and self-seed next time. But we can let the seeds dry and then collect them to plant.

The only trouble is, that plants may create seeds in different ways. Some seeds come from the “fruit”, like tomatoes, cucumbers and squash. Others “go to seed” and create seeds from flowers or pods. It is quite interesting.

Here is a photo of the dill plant that produced beautiful flowers that turned into hundreds of seeds.

I ended up with too many dill plants. I dug them up and put them all around the edge of the yard. They are very hardy and don’t need much attention. I love dill and fennel (they are very similar looking) because their flowers attract beneficial insects. I do collect the leafy parts to chop and use when cooking.

  1. Keep the dill seeds and use for cooking – I cut the whole heads into a
    paper bag, and then shake them off once they are totally dry – don’t cut
    them until they are quite brown.

    Do the same with coriander that always goes to seed really fast!

    Lettuce gets bitter when it doesn’t get enough water. So it doesn’t grow
    fast enough.

    But some lettuce varieties are more bitter than others. I don’t like
    Rocket/arugula because it is too peppery and bitter but evidently it is
    good for you!

    1. Fennel and dill both have loads of seeds. I’ve never grown coriander. Lettuce is tricky, but I do like the peppery arugula. It’s especially good mixed in with greens. I’ve also added a few leaves when making broth. Do you crush your dill seeds before using?


      1. We actually got dill seeds for one recipe and I can’t remember what I
        did with the seeds – maybe crushed them? But you could google for that
        info. The actual dill fronds are nice chopped into salads – the fennel
        fronds are stronger – I think it is the fennel that tastes like
        liquorice – a friend eats the fennel bulb – I don’t as I’m not keen on
        the flavour.

        Coriander is called cilantro in the USA.

      2. Yup, that is how I use the dill – the leaves. I’m not keen on fennel either, but I grow it for the bugs that love the flowers.
