Seed Story

What lettuce is strongest in the Force?

Jadeite was the winner of our 2019 lettuce trials.

This is a little green romaine lettuce bred by Frank Morton of Wild garden Seeds. It came from a cross between Winter Density and Dark Green Romaine.

We were looking for a compact little lettuce to add to our seed catalog. Something nice and tidy that fits cosily into a garden and is perfect for a 1-2 person salad.

Jadeite not only held well and looked good in the field, but it delivered a sweet crunch in our taste trials too! Not to mention winning Cutest Lettuce In Show.

Sometimes, we keep a variety in trials for a couple of years to make sure we really want it in our catalog. And sometimes, you find a Jadeite and it makes the cut immediately.

So, what lettuce is strongest in the Force?

Well, Jadeite obviously! 

As my co-farmer Julien pointed out, Jadeite can sort of be pronounced Jedi in French.

HOW TO HARVEST

Lettuce can be grown as a head or as a baby salad green.

To harvest lettuce as a  baby salad green - cut when leaves have reached desired size. Cut above the growing tip to allow for regrowth and multiple harvester.

To harvest full lettuce heads, wait until the lettuce has formed a head and then cut at the base of the plant. Remove any damaged outer leaves. (Butterhead varieties will make a ball in the centre. Romaine varieties will be tall and compact)

HOW TO KEEP SEEDS

• Lettuce does not easily cross pollinate with other lettuces. It is very easy to keep true to type.
• Lettuce is an annual plant that will produce seed its the first year
• Allow lettuce head to bolt and elongate
• Consider removing bottom leaves to promote airflow and prevent disease
• Begin harvest when flowers have formed clusters topped with white fluff
• Not all seed clusters will be ready for harvest at once. The entire stalk can be harvested when 50% of the clusters are mature, or you can return every day to harvest newly matured clusters
• Harvest by shaking into a paper bag and leave to dry for 3-6 days
• Use a colander to separate seeds from any fluff or chaff.
• Winnow seed from chaff with an electric fan
• Store seed in a cool dry location.
