Herb
Chives
Chives defend romanesco from cabbage moths and flea beetles through sulfur compound repulsion and pest confusion.
Flower
Calendula
Calendula attracts parasitic wasps that control cabbage moths and other brassica pests affecting romanesco.
Vegetable
Celery
Romanesco's brassica structure provides light overhead shade protecting celery from excessive sun while improving moisture retention.
Situations where this plant is a reliable fit — from someone's kitchen sill to a wind-blown rooftop.
Balcony
A few pots on a flat outdoor perch — some sun, some wind.
Grow bag
Cheap flexible bag, 20–40 L — hungry crops with big roots love these.
Reused bucket
A salvaged 10–20 L bucket with drainage holes — a proper productive pot for very little cost.
Raised bed
A traditional plot or timber-sided bed — deepest root run, widest planting choice.
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.
