In medieval Europe, rhubarb was a rare luxury. In fact, being several times the price of other valuable herbs and spices such as cinnamon, opium, and saffron, only the very rich could afford to indulge in its unique, tart flavour.

While rhubarb is usually sold as pot-grown stock in the spring, there is nothing stopping you from growing your own plants from seed. Of course the various rhubarb cultivars will not grow true to the parent plants, but there are a small number of specialist varieties which will. The most popular being Rhubarb 'Glaskins Perpetual'.
Prepare the soil in advance over the autumn or winter by digging in plenty of well-rotted manure or garden compost. Remove all weeds, especially perennial weeds.
Using a large modular seed tray, or 3 inch pots, fill with a good quality compost such as John Innes 'Seed and Cutting'. Sow rhubarb seeds individually at a rate of one seed per pot, or module, at a depth of ¼ inch anytime from March to April. Gently water in the place the tray or pots inside a heated a propagator at a temperature of between 20-25 degrees Celsius. Alternatively seal inside a clear polythene bag and leave on a warm bright windowsill. Germination will usually take between 21- 40 days. Keep the soil damp but avoid waterlogging.
