Herb
Chives
Chives repel aphids and spider mites that damage lettuce while their mild onion flavor complements cos in salads.
Root
Radish
Radish breaks soil crust for lettuce roots while maturing faster, harvested before lettuce needs space.
Root
Carrot
Lettuce's shallow roots and carrot's deep roots avoid competition while providing beneficial shade.
Flower
Viola / Pansy
Viola's edible flowers attract beneficial insects while providing shade to protect lettuce roots from heat stress.
Situations where this plant is a reliable fit — from someone's kitchen sill to a wind-blown rooftop.
Windowsill
Bright indoor light, small pot, no outdoor access — the classic kitchen sill.
Balcony
A few pots on a flat outdoor perch — some sun, some wind.
Vertical wall pocket
Living-wall pouches or stacked planters — very shallow roots only.
Ladder planter
A tilted step-ladder with a shallow tray on each rung — sun-facing, five tiers of herbs, salad and strawberries in the footprint of one pot.
Pallet wall garden
A wooden pallet stood upright and lined with landscape fabric — every slat becomes a shallow salad-or-herb pocket. Cheap, huge productive area, needs frequent watering.
Pocket planter
A canvas or felt panel of sewn-in pockets, hung on a sunny wall — instant vertical garden, works well on a balcony rail too.
Wooden crate
A shallow wine or veg crate lined with hessian — perfect for salad and shallow-rooted herbs.
Raised bed
A traditional plot or timber-sided bed — deepest root run, widest planting choice.
Water jar
A jam jar of water on the sill — no soil at all. Regrow from kitchen scraps.
Root in water, transfer to soil

How to do it
Same as standard lettuce.
What to expect
Crunchy small leaves for ~2 weeks.
Honest note
Bolts a bit slower than butterhead — slightly longer harvest window.
Where to source

Shop local first
The best plants come from a real nursery, and the best trowel comes from the old-fashioned ironmonger down the road — people who know their stock and can advise. Try local first, both for the plant and the kit. It keeps small growers and small hardware shops alive.

For pots, compost, seed trays, twine and other kit — Amazon has the essentials if the local option isn't right. Not a plant nursery; use the local map above for the plant itself.
