Italian Rabarbaro is a robust perennial rhubarb with thick flavourful stalks. Plant it once and harvest for years. The tart, acidic stalks are perfect for jams, compotes, pies and classic stewed rhubarb with cream.
Rhubarb thrives in Irish conditions. Give it a corner of the garden, feed it with compost in spring, and it will reward you with more stalks than you know what to do with. One of the easiest and most productive perennial crops you can grow.
🌱 Sowing information
Sow from mid‑July to the end of September in fertile, well‑drained soil. Start in modules or sow directly outdoors. Allow plants to establish fully during the first year and begin harvesting from the second year onward.
☀️ Light exposure
Prefers full sun but tolerates partial shade. Sunlight encourages strong stalk development and richer flavour.
💧 Water needs
Keep soil consistently moist during establishment. Once mature, rhubarb is relatively drought‑tolerant but benefits from regular watering during dry spells.
🌡️ Germination temperature & time
Seeds germinate best in warm soil (15-20°C). Germination typically occurs within 10-20 days.
📏 Plant spacing & final size
Space plants 80-100 cm apart. Mature plants form large clumps with broad leaves and thick, harvestable stalks.
