Why is it that so many of vegetable plants go to seed before 'hearting'. Mainly lettuce?

Hi John, not sure if your question is about your garden, or just seeding in general. I had total failure with my lettuce this year. I planted in November, and the Sydney summer was just too hot. In some areas classed as temperate climate you can plant all year, but this guide can't fit everyone. Where I live is generally 6 degrees hotter than Sydney CBD throughout summer, so trying lettuce at that time of year was stupid. Lesson learned. Regarding bolt in general, I think it's really just that plants will do anything to survive. I'm no botanist, so this is all my opinion only. If the conditions are perfect, the plant has the energy and nourishment to produce a harvest. As conditions move further away from ideal, the plants behaviour becomes less about producing a large crop (showing off), and more about survival. When conditions are untenable, the plant will abandon the crop, and put all available energy into producing seeds to try again next year. That's bolt as I understand it, I'm more than happy to be corrected.

Lettuces like cooler weather. Varieties like Iceberg, Imperial 847, Imperial Triumph will bolt to seed readily.Great Lakes, Penn Lake, Yatesdaale will tolerate warmer conditions but are a coarser leafed lettuce.
