It takes 45-50 days to harvest and can withstand temperatures down to -9.4 degrees C (15 degrees F). Tatsoi can be harvested even from under the snow, making it one of the best vegetables to grow in a cool climate.

How to grow
This vegetable is strongly resistant to cold weather. Seeds are sown from spring through fall. This is a vegetable with unique appearance - spoon shaped dark green leaves arranged in a rosette of concentric circles. Stalks are short and plants grow relatively slower than other Pak Choy varieties. Young leaves are very delicious. Plants can be harvested anytime during the growth.

Cooking information
Leaves can be eaten raw or cooked. The leaves are tougher and stronger flavoured than standard pak choy and hence many prefer cooked (stir-fried, steamed or in soups) rather than raw. Young leaves can be used in salad.

Nutrition information
Tatsoi is very high in calcium and vitamins and is twice as nutritious and twice as delicious as ordinairy Bok Choy.

TI Plant (Luckyplant) 朱蕉





Ti plants or cordylines, are extremely popular worldwide for their intense leaf colors and leaf shapes producing interest and contrasts even in deep shade. Native to Eastern Asia to Polynesia, ti hybrids have names in English, French, Japanese and Hawaiian

Pictured above is 'Pink Sister' known in many places as the 'Hawaiian Ti' plant

Natives use plants for fiber, cloth and livestock food. The roots are said to be edible

By the way, Ti is pronounced like 'tea' in some areas, but in Florida the name rhymes with 'hi.' Correct is the 'tea' version

Mistakenly said to be related to dracaena, cordylines are tropicals and seen happy outdoors only in South Florida. Even our zone 10 winter temperatures cause leaves to "rag" with the edges turning brown on most. Spring pruning of all poor leaves is standard maintenance

This plant is tolerant of most soil conditions, but does not work well near salt spray conditions.

Water moderately and feed normally. Provide good drainage.

Stems can be cut almost any time and cuttings can be inserted into the ground to start a new plant. The mother plant will branch with new stems and new leaves if you do. This type of pruning is necessary over time as stems can grow too tall (up to 8-10 feet) for the landscape affect originally intended

With little care. Ti plants can be wonderful houseplants as well. Stem cuttings can also be inserted into a vase with 2-3 inches of water and your ti will grow roots very easily
