Amaranthus tricolor. Callaloo Amaranth seeds are grown all over the Caribbean to cultivate baby leaves for the dish known as Callaloo. There are many regional variations to this dish of cooked greens, some with spicy peppers added, some with meat or fish. Callaloo Amaranth makes excellent micro-greens, but we grow them to the immature size of about 30cm (12″) tall, while the leaves are still tender. Left to grow to full maturity, the plants will develop elegant, dangling flower clusters just like our Green Tails. The flowers and seeds are also edible, but may end up in a vase instead. Matures in 40-60 days.

Timing: Direct sow in late spring, once night time temperatures are steadily above 10°C (50°F). Optimal soil temperature for germination: 18-24°C (65-75°F).

Starting: Sow seeds 5mm (¼”) deep in well drained soil in full sun. Seeds should germinate in 4 to 10 days. Thin seedlings to 25-35cm (10-14″) apart in rows 50cm (20″) apart.

Growing: Ideal pH: 6.0-7.5. Keep moist until germinated, and then simply keep the area weeded.

Harvest: Pick baby or mature greens as needed. Simply cut them with scissors as one would with mescluns. The leaves have an appealing, nutty flavour. If growing for seed, choose A. hypochondriacus and provide ample spacing. Seed will ripen in late summer or early fall. Watch for birds visiting the plants. Rub the flower heads between your hands over a bucket or tray. Doing this into paper yard waste bags works well. If the seeds do not fall easily, leave the plants for one more week and try again.

The mildest flavoured and easiest to grow of the radicchios, this sugarloaf type grows light green heads that are tall and slender like an extra tall romaine. Nettuno can be grown early spring through late fall, with good tolerance to hot temperatures and resistance to tipburn. Heads are well wrapped within large outer leaves and are dense when fully mature.

How To Grow, Timing:  Sow after the last frost date and again in mid-summer to take advantage of the fall growing season. Optimal soil temperature: 10-22°C. Seeds sprout in 2-15 days, depending on conditions. In hot weather plants may go to seed quickly, so have new plantings ready to go.

How To Grow, Starting:  Either direct seed or start indoors and transplant. Sow seeds 5mm deep, and thin or transplant to allow 30-45cm between plants in rows 30-45cm apart.

How To Grow, Growing:  Ideal pH: 6.0-6.5. Enrich soil with compost and add ¼ cup balanced organic fertilizer into the soil beneath each transplant. Rapid, continuous growth is essential for good yields and high quality. Regular watering is essential. Fall plantings can be protected from rain by putting a cloche over them. Endive heads can be blanched to reduce bitterness by placing a cardboard or plastic disc on top. Radicchio requires a good supply of phosphorus and potassium, but will not head and may bolt if there is too much nitrogen available. Days to maturity shown are from date of direct sowing. If transplanting, subtract 10-15 days.

How To Grow, Harvest:  Use as a cut and come again crop or let the heads develop and cut at ground level. Many will grow back.

Known in Italy as Catalogna frastagliata, Italian Dandelion Chicory Seeds produce not a dandelion, but a chicory, a kind of endive. Fast growing, upright, dark-green notched leaves stand in thick bunches. Cut the plant at any height and it will re-grow again. Steamed like spinach, they have a pleasant “wild” flavour. Raw, they add bite to salad. May bolt mid-summer from spring planting. Italian dandelion chicory is quite winter-hardy, and suitable for winter gardening. If allowed to bloom, it sends up tall stalks of attractive, edible blue flowers that produce seeds that are easy to harvest and save for next season.

How To Grow, Timing:  Sow after the last frost date and again in mid-summer to take advantage of the fall growing season. Optimal soil temperature: 10-22°C. Seeds sprout in 2-15 days, depending on conditions. In hot weather plants may go to seed quickly, so have new plantings ready to go.

This vigorous red heirloom variety has bright burgundy leaves with green centres that are great for baby leaf salad mixes. Red Salad Bowl lettuce seeds form big rosettes with the deeply indented leaves that we love in an oak-leaf lettuce; and is slow to bolt, tender, and mild-tasting. The bright red colour is best in cool temperatures. This popular lettuce grows well all year long, and right through winter if grown in a cold frame or polytunnel. Try some in patio containers for the convenience of picking individual leaves for salads and sandwiches.

How To Grow, Timing:  Lettuce grows best in cool weather in the spring and fall, but it can be grown in the summer, and all winter long in milder regions. Sow short rows every 2-3 weeks following the last average frost date for a continual harvest. Using a cloche, cold frame, or greenhouse over mid-late summer plantings can extend the harvest period right into winter. Optimal soil temperature for germination: 10-22°C. Seeds should sprout in 7-15 days, depending on conditions. Lettuce seeds don’t sprout easily when the soil temperature is over 22°C in summer. Get around this by sprouting them indoors in a cool area, or pre-sprout by sprinkling seeds on a damp paper towel and placing it in a plastic bag in the fridge for a few days. In hot weather most lettuce goes to seed rapidly, so have new plantings ready to go, and watch for “good resistance to bolting” in the product description.

How To Grow, Starting:  Direct sow or start indoors and transplant. Sow seeds 5mm deep, or on the surface of the soil where the soil can be kept evenly moist. Space or thin heading lettuce to 30cm apart. Space or thin looseleaf varieties to 20-25cm apart. Space rows for all types 45-90cm apart. Babyleaf lettuce can be planted quite densely, as it is harvested at an immature size. Sowing babyleaf lettuce seeds closely together in narrow rows makes harvesting simpler.

Note on Pelleted Seeds: A number of our lettuce seeds are pelleted for machine planting. The white clay ball that covers each seed makes them easier to handle and easier to see when planted. While most lettuce seeds need to be barely covered (or sown on the surface of the soil), pelleted seeds need to be buried by about 1cm. Please keep your newly sown pelleted seeds evenly moist – use more water than with conventional seeds. If the soil is allowed to dry out, the clay pelleting material can wick water away from the seed, causing uneven or lower germination.

How To Grow, Growing:  Ideal pH: 6.0-6.5.  Aim for a soil with ample drainage and lots of organic matter. Add compost and lime at least 3 weeks prior to planting. One cup of balanced organic fertilizer per 3m of row will give adequate nutrition. Seedlings should be hardened off by reducing water and putting the plants outdoors 2 or 3 days before transplanting. This will help to prevent transplant shock and premature bolting. Regular watering is essential to prevent leaves from developing a bitter taste.

How To Grow, Harvest:  Pick individual leaves or wait and harvest full heads. Mature summer lettuce stays in prime eating condition only a short time, so harvest promptly and keep planting. In fall and winter the plants stay in good harvest condition longer.

This red-spotted, open romaine lettuce is sure to turn some heads. The mid-sized plant is open with glossy, green leaves flecked with maroon; making it a delightful and colourful addition to salad mixes. As the leaves get larger, the markings become even more prominent. The leaves of Freckles lettuce are speckled, not blotchy, so they have quite an elegant look. And the flavour is excellent. Freckles lettuce seeds, also known as Forellenschluss are an heirloom variety of Austrian lineage. Be sure to plant some Freckles lettuce seeds in your organic vegetable garden this spring.

Flavourful pale centres are surrounded by thick green outer leaves on enormous upright plants. Parris Island Cos romaine lettuce seeds can be planted close together for a long harvest of little leaves for gourmet salads. Given space and time to grow to full size, Parris Island forms huge heads up to 30cm tall, but even at this crazy size, the leaves are tender and succulent, with mild flavour. Dating back to 1952, this heirloom lettuce is named after the actual Parris Island off the coast of South Carolina. Parris Island Cos is tipburn and mosaic tolerant.

Medusa is one of the prettiest kales available with its dark green, heavily frilled leaves and contrasting bright purple stems and veins. Plants are tall and vigorous, and the stems are long and sturdy for easy harvesting and bunching. The thick waxy leaves hold up well on the plants and after harvesting. Excellent cold tolerance for harvesting through the fall. Plants grow 60-80cm tall.

How To Grow, Timing:  Direct sow in early spring to mid-summer for summer to winter harvests. Or start indoors 4-6 weeks before the last frost, and transplant out as soon as the soil warms up. Optimal soil temperature: 10-30°C. Seeds should germinate in 7-10 days.

How To Grow, Starting:  Sow 3-4 seeds 5mm deep in each spot you where a plant is to grow. Thin to the strongest plant. Space 45-60cm apart in rows 75-90cm apart.

How To Grow, Growing:  Ideal pH: 6.0-6.8.  Add lime to the bed 3 weeks prior to sowing. Kale likes well-drained, fertile soil high in organic matter. This plant prefers plentiful, consistent moisture. Drought is tolerable, but quality and flavor of leaves can suffer. Mix ¼ cup of complete organic fertilizer into the soil beneath each transplant, or use 1 cup beneath every 3m of seed furrow.

How To Grow, Harvest:  Kale and collards can both be grown as a cut and come again crop for salad mixes by direct-seeding and cutting when plants are 5-8cm tall. They will re-grow. Or pick leaves from the bottom up on mature plants as you need them. In spring, the surviving plants start to flower, so eat the delicious flowering steps and buds.

These uniform, compact plants are the best kale choice for harvesting all in one go at 45cm (18″) tall. The dark blue-green leaves are very tasty, and appealingly curled, with short internodes – meaning they’re packed more tightly on the stem than other types. Sow Starbor kale seeds for your small farm and use mechanical harvesting, or sow them for your raised allotment bed and enjoy a huge crop of nutritious super-food. Starbor kale seeds do not need warm soil to germinate, so they can be started outdoors as early as March here on the coast. In colder climes it is sensible to start some indoors for transplanting when the warm weather arrives. Winner of the RHS Award of Garden Merit.
