Rosela' is an early lettuce (Lactuca sativa) with large crinkled leaves that have a burgundy red colouring. Can be used as a cut and come again lettuce by harvesting outer leaves or harvest as a whole head which is ready in about 50 days from sowing. Crisp and good taste perfect for salads and sandwiches.
Being an early variety means it has a relatively short vegetative period and so is a good variety for saving seed from in Irish conditions where plants need to flower and set seed before the weather conditions decline. It is cold tolerant so with successional sowing you should be able to have fresh leaves most, if not all, of the year round.
Lettuce is best grown as transplants. Can be started off in modular trays from as early as January if you have a heated propagator (be careful to not let lettuce seed get above 23°C as the seed can go dormant then and not germinate). Sow seeds very shallowly or just sit on top of the compost and water gently. From spring no additional heat should be required.
