Watercress growing from supermarket bought cuttings. (Nasturtium officinale) 西洋菜/豆瓣菜繁殖自超市買來的小把菜中挑粗的來扦插.

This hardy aquatic perennial is common vegetable that you can find in any supermarket nowadays.  Very cold tolerant and easy to grow from cuttings or seeds.  Best in full sun to partial shade location.   When you harvest just cut the top tender shoots with young leaves then the rest of plants will continue to grow rapidly.  Do not introduce it to wet land because its invasive growth.   Small white flowers from late spring to mid summer and do grow seeds easily.   I find it is easy to grow from cuttings and you can get a bundle of them with good price in the supermarket vegetable isle.  Just save few thicker cuttings then grow them in a pot will wet soil.   Keep the pot moist/wet (I keep the pot in a small container) and in full sun to partial shade location.  USDA Zones:5-11.  Easy to grow and propagate.   Propagation from seeds or cuttings or dividing the plant clumps.   As food you can eat it raw as salad or cook in water or oil.   Medicinal.   Fast growing.

這種菜是多年生草花,非常強健的水生植物. 也是超市中常見的葉菜區中小把小把在賣的.  非常耐寒並且容易栽種,容易繁殖自超市買來的小把菜中挑粗的來扦插或是買種子來播種.   以栽種在全日照的濕潤土壤/積水的泥土中為佳.  勿種在開放水域以免繁殖到不可收拾.  春末到仲夏開白色的小花並容易結子.  由於超市賣的不貴只要留幾枝稍粗的來扦插比種子栽種的快.  只要維持盆土的濕潤就可以了(我是把盆放在小提桶中放在全日照到半日照處讓它們生長.  耐寒且耐熱.  易栽種及繁殖.  繁殖以種子/扦插/分株方式皆可.  它可當沙拉生吃或煮熟食用. 生食有辛辣味. 可藥用.  生長極為快速.

  1. I love watercress in early spring. We used to collect it out in the country and it looks a little different from what you have there. I should check the store to see if they have any I could grow.
