Calendula (Calendula officinalis) grows well on a balcony in a suitable container. It needs full sun — around 6+ hours of direct sun a day. Blooms from summer to early autumn (spring to fall); deadhead regularly to prolong flowering. All figures below are sourced from RHS and the Old Farmer's Almanac.

Harvest
Blooms from summer to early autumn (spring to fall); deadhead regularly to prolong flowering
Good companions: Cabbage and other veg (draws pollinators, hoverflies and parasitic wasps; helps deter aphids and caterpillars)
Balcony tip: An unfussy hardy annual that flowers best in full sun and copes with poor, dry soil, so it is well suited to containers; deadhead and pinch out tips for bushy, long-flowering plants with edible petals
