I've grown Little Gem for 6 years. Consistent germination, nice flavour, grows well in pots/beds. A bit longer than leaf lettuce to mature, but worth it. Prefer loose seed to the tape, but tape works too.
I've grown Sparky for 5 years, they never disappoint. Easy to germinate, beautiful burnt orange/gold flowers that bloom til hard frost. (Zone 4b Ontario) Great in pots or my flowerbeds. Pollinators love them too!
this is my absolute favourite variety of lettuce. It grows well, doesn't bolt in the heat and is soo buttery in texture. It's a must have in my garden
