Lettuce is one of the few vegetables that hasn't been hybridized to death and there are hundreds of tasty self-pollinating varieties available. Unfortunately, the lettuce transplants you find at farmer's markets and garden centers are usually hybrids, bred to ship well and stay fresh longer, not for flavour. Investing in a $3 packet of open-pollinated or heirloom lettuce seeds can reap rewards for years to come since it's so easy to keep on saving the seeds. Lazy gardeners like me just let their lettuce bolt at the end of summer and find it usually re-seeds itself the next year. It may not come up exactly where you want it to, but the small seedlings are easily moved.
Because most lettuce is self-pollinating its easy to save seeds that will be exactly like the parent plant. Choose one of your best lettuce plants, don't pick it and keep watering & feeding it until it flowers. (You can pick some of the outside leaves for eating without harming seed production.) Lettuce sends up a tall branching flower stalk topped with small yellow daisies. Harvest the entire stalk when the seeds are ripe - about two to three weeks after flowering. Hang it upside down inside a paper bag in a dark, dry place for a few days until completely dry. Store in an airtight container in a dark place until next year.
Colourful Lettuces for Containers:
A red oakleaf lettuce with amazing flavour. Large heads hold up well in the summer heat. Ruby wine colour looks great on the balcony garden. Space 6 in./ 15 cm. apart in containers.
This teeny-tiny butterhead (boston-style) lettuce dates back to 1853. It's a very early variety with deliciously soft leaves. Each head makes a tiny salad for one person. Perfect for container gardening - should be spaced 2-3 in./ 5-7 cm. apart.
Black Seeded Simpson
An 1850 heirloom leaf lettuce, with light green crinkly cut leaves. Good mild flavour, matures early, great yields. As with most leaf lettuces, if you keep picking the outer leaves, the plant will continue to produce foliage until it finally flowers. Space 8 in./ 20 cm. apart in containers.
A medium-sized, mild-tasting butterhead lettuce. Pale green heads are tinged with red. Can tolerate early spring plantings - matures in 45 days so perfect for the Ottawa area. Space 8 in./ 20 cm. apart in containers.
A Bibb-type lettuce with unusual deep burgundy leaves with ruffled edges. One of the most beautiful red lettuces I have grown - the colour holds all summer. Tolerates hot humid summers - very slow to go to seed. Space 6 in./ 15 cm. apart in containers.
This large Italian Heirloom butterhead lettuce has gorgeous bright green ruffled leaves with a hint of bronzy-pink at the leaf margins. Crisp texture, sweet taste, and very slow to bolt. Space plants at least 12 in./ 30 cm. apart in containers.
