A multitude of 2-inch, golden-yellow daisy flowers sits atop thready foliage from late spring to late summer if deadheaded promptly. This clump-forming perennial is native to the central and southeastern U.S. It is sometimes grown as an annual. It makes a beautiful cut flower, and its casual habit makes it valuable in cottage gardens, borders, containers, and meadows.Noteworthy characteristics: Golden-yellow flowers over a long season. Fast-growing.Care: Needs well-drained, fertile soil in full sun or partial shade. Deadhead regularly. Support as needed.Propagation: Sow seeds in a seedbed in mid-spring or divide in early spring. Root basal cuttings in spring.Problems: Slugs, snails, bacterial spot, rust, Botrytis flower blight, aster yellows, powdery mildew, downy mildew, fungal spots.

形态特征 多年生宿根草本，叶片多对生，稀互生、全缘、浅裂或切裂。花单生或疏圆锥花序，总苞两列,每列3枚，基部合生。舌状花l列,宽舌状，呈黄、棕或粉色。管状花黄色至褐色。主要种类:金鸡菊，大花金鸡菊，大金鸡菊，轮叶金鸡菊。
繁栽要点 金鸡菊类耐寒耐旱，对土壤要求不严，喜光，但耐半阴，适应性强，对二氧化硫有较强的抗性。金鸡菊栽培容易，常能自行繁衍。生产中多采用播种或分株繁殖，夏季也可进行扦插繁殖。播种繁殖一般在8月进行，也可春季4月底露地直播，7-8月开花，花陆续开到]0月中旬。二年生的金鸡菊，早春5月底6月初就开花，一直开到10月中旬。欲使金鸡菊开花多，可花后摘去残花，7-8月追一次肥，国庆节可花繁叶茂。用途 金鸡菊枝叶密集，尤其是冬季幼叶萌生，鲜绿成片。春夏之间，花大色艳，常开不绝。还能自行繁衍，是极好的疏林地被。可观叶，也可观花。在屋顶绿化中作覆盖材料效果极好，还可作花境材料。

Aquilegia 'McKana Hybrids'

Common Name: Columbine

A series of hybrids that has stood the test of time. 'McKana Hybrids' come in a wide range of pastel colors, many of them bicolors. They are prized for their large, showy flowers with long, widely flared spurs. So beautiful they sell on sight!

Aquilegia is especially lovely when allowed to naturalize in shady, woodland borders. They also have excellent potential as cut flowers, lasting up to 2 weeks in a vase.

Origin: Not Native to North America

至于耧斗菜的中文名称的来历一直未能查到。

耧（音：lóu），播种用的农具，前边牵引，后边人扶，可同时完成开沟和下种两项工作：～车。～犁。～播（用耧播种。亦称“耩地”）。耧斗菜使用的“耧斗”这个词在现成的词典中一直没找到。从形象的角度来看，在北方农村经常使用一种用来耧草的耙子，一般是用一根根8号铁丝，按一寸左右的等距离排列，穿进两根横的木条中心固定成，着地一头专门用于耧草的铁丝则弯成钩，与耧斗菜的花的内弯的短距或长距极其相似，也许这就是耧斗菜中“耧”之来历，至于“斗”嚒，应该考虑花的形状了：此花上大下小为一斗状，于是两者结合谓之曰“耧斗”，尽管形状似漏斗，但未见正式文章中称“漏斗菜”或“漏斗花”。
