Scientific Name Lamium galeobdolon (L.) L. [图片]Common Names Yellow Archangel, Artillery Plant, Aluminium Plant Synonyms Galeopsis galeobdolon (basionym), Galeobdolon luteum, Lamiastrum galeobdolon Scientific Classification Family: Lamiaceae Subfamily: Lamioideae Tribe: Echinocereeae Genus: Lamium [图片]Flower Color: Yellow Bloom Time: Mid-spring to early summer Description Lamium galeobdolon is a large-leaved perennial plant, up to 31 inch (80 cm) tall. The leaves are paired, opposite, stalked, broadly ovate with a cordate base and toothed margin. The underside of the leaves is often purplish. The small, two-lipped, yellow flowers, often streaked with orange, appear in whorls on short axillary stalks up to 0.75 inch (1.9 cm) long, in late spring. [图片]How to Grow and Care Lamium is undemanding and easy to grow in partial to fully shaded locations. It prefers well-drained soil but will do fine in dry shade if you provide it with regular watering. A member of the mint family, Lamium spreads quickly, is self-seeding, and will rapidly create a groundcover wherever it is planted. Its brittle, fragile stems help keep it from becoming aggressively invasive and also allow bulbs and other perennials to penetrate its foliage. In regions with cold winters, Lamium is deciduous. In milder climates, it is semi-evergreen. In either case, cut back shabby foliage after the first frost to make way for new growth in the spring. In midsummer, after the blooming period is over, prune plants back by one-third to help prevent them from becoming too invasive. The midsummer shearing also encourages a second blooming period in September. Not terribly picky, spotted Dead Nettles do just fine in average, well-drained soil. There is no need to apply fertilizer, as this can encourage them to become too robust and invasive. Origin Native to Europe and western Asia.

Scientific Name Laburnum anagyroides Medik. [图片]Common Names Common Laburnum, Golden Chain, Golden Rain, Golden Chain Tree, Laburnum, Peatree Synonyms Cytisus alschingeri, Cytisus laburnum, Laburnum vulgare Scientific Classification Family: Fabaceae Subfamily: Faboideae Tribe: Genisteae Genus: Laburnum [图片]Flower Color: Yellow Bloom Time: Late spring Description Laburnum anagyroides is small deciduous tree or large shrubs up to 30 feet (9 m) tall. The branches are spreading, smooth bark, dark green in color. Leaves are trifoliate, up to 2.8 inches (7 cm) long, comprised of alternate leaflets, each up to 3.2 inches (8 cm) long and up to 1 inch (2.5 cm) wide. The flowers are golden yellow, sweet scented, densely packed in pendulous racemes up to 10 inches (25 cm) long, and typically bloom in late spring. [图片]How to Grow and Care Choose a growing site that is exposed to full sunlight. The more sunlight, the better the Laburnum will bloom. An exception to this rule is home gardeners who live in USDA zone 8. Laburnums do not tolerate heat well, so gardeners who live in hotter climates should choose a location that gets morning sun but is shaded from direct exposure to hot afternoon sunlight. Plant your Laburnum in rich, well-drained soil. These trees are small — they average about 20 feet (50 cm) in height — so they can also be grown in containers. If you use a container, make sure it has drainage holes. Water frequently. These trees thrive in cool, moist soils and grow best in climates that have mild, wet summers. Water at least once each week — more often when the weather is hotter than usual. Fertilize in early spring, before bud break. Use a fertilizer formulated for flowering trees and shrubs, and one that has a high acid content. Laburnum thrive in high pH soils. Follow the directions on the package according to the size and age of your Laburnum. Origin Native to Central and Southern Europe.

Scientific Name Crocus tommasinianus Herb. [图片]Common Names Early Crocus, Woodland Crocus, Tommasini’s Crocus, Botanical Crocus, Snow Crocus, Lilac Tommy, Spring Bulbs, Spring Flowers Synonyms Crocus serbicus, Crocus vernus var. tommasinianus Scientific Classification Family: Iridaceae Subfamily: Crocoideae Genus: Crocus [图片]Flower Color: From lilac to deep purple Bloom Time: Early spring Description Crocus tommasinianus is a cormous perennial with a lilac flower, and is one of the smaller of the cultivated species of the genus Crocus. It has long tubed flowers, up to 1.6 inches (4 cm) long, which appear in early spring, as the narrow leaves emerge. The flowers vary from lilac to deep purple, sometimes paler outside. [图片]How to Grow and Care Crocus bulbs need well drained soil in a sunny to partially sunny location. They thrive in a soil pH of 6 to 7 and are tolerant of a wide range of soils. You may even grow Crocus in the lawn but be careful as they will naturalize and spread to become a potential nuisance. Plant the Crocus bulbs in groups in the garden bed for impact or even under trees, as they need little root space. Bulbs are planted 3 inches (7.5 cm) deep and 3 to 4 inches (7.5 to 10 cm) apart. Provide mulch over the planting area in very cold zones but rake it away in early spring so the flowers can emerge. Gardeners in zones where the winters are too harsh or too warm to plant in fall can force the Crocus bulbs indoors in time for a spring planting. Animals can be a big problem with Crocus bulbs. Squirrels and other rodents will dig up the bulbs and eat them, and deer will graze on the early foliage. You can cover the spring bulb bed with wire mesh to prevent squirrel damage, and there are deer repellents you can try to prevent their feeding on your flowers. Origin Native to Bulgaria, Hungary, Albania, and the former Yugoslavia.

一、#君子兰 1、缺少磷钾肥 磷、钾能够促进花芽的分化，而氮肥则会促进君子兰叶片的生长。 解决方法： 在君子兰开花之前，要多施磷钾肥，比如，磷酸二氢钾、充分腐熟的鱼虾壳或者是鱼肠水、蛋壳、骨粉等等。 大约7~10天1次，注意薄肥勤施。 2、光线不足 君子兰不能暴晒，可能不少花友会把君子兰放在比较荫蔽的地方，君子兰不能接触到足够的光照，光合作用减弱，自然就没办法提供更多的养分让它分化花芽了~ 解决方法： 最好将君子兰能放在隔着玻璃的南阳台上，同时每隔1周转一下花盆，不然君子兰的叶子容易长歪。 [图片]二、长寿花 1、光照不够充足 长寿花喜光，只有光照充足才能长势良好，光照不足的话，枝叶徒长，枝条细弱，能长出花苞来才是怪了！ 解决方法： 将长寿花放在南阳台或者是南窗台，这种光照非常好的地方哦~ 2、肥料不足 长寿花的花期非常长，一年能开好多次花，这也就意味着对肥料的需求很大，因此，一直不给长寿花施肥，还想让它开爆盆，就是一件非常玄幻的事情了~ 解决方法： 现在正好是长寿花的花芽分化期，需要每周1次充分腐熟的鱼肠水等，比例为1：50。想要速效的话，可以直接喷磷酸二氢钾，很管用的。 [图片]三、三角梅 1、浇水问题 三角梅喜欢湿润的环境，所以一般养殖三角梅的花友，浇水都会比较多，但是一直保持湿润的环境，就很容易造成三角梅光长叶子不开花的后果。 解决方法： 控水，大概15~20天浇水1次，同时多晒太阳，让三角梅产生危机感，循环2~3次，三角梅就会长花苞了。 2、光照不足 有些花友是在室内养殖的三角梅，可能放置的位置不是很恰当，光照不是很充足，所以三角梅就会不开花。 解决方法： 三角梅最好能露天养殖，光照越好开花越多，如果没有露天的条件，请务必放在光照非常好的南阳台，谢谢。 3、枝条过于密集 三角梅很容易生出侧枝来，不少花友都舍不得剪掉，但实际上，这些枝条会分散营养，从而导致枝条上不容易生出花芽。 解决方法： 每年春天的时候都要把弱枝、病枝、徒长枝条减掉，减少养分的消耗，开花后也要把花梗剪掉哦。 [图片]四、蟹爪兰 1、温度过低 蟹爪兰的适宜生长温度为15℃以上，但是它的花期却在10~来年2月份，而这段时间内，正好气温都比较低，如果室内的温度不能达到15℃以上，它就会很难孕育花蕾的。 解决方法： 将蟹爪兰放在室内养殖。 如果冬天室内的温度也达不到15℃以上的话，可以用塑料袋给蟹爪兰做一个小温室。 2、总是搬来搬去 有些花友为了让蟹爪兰有充足的光照就会把它搬来搬去，殊不知，这才是导致蟹爪兰不开花的元凶啊！而且长出了花苞的蟹爪兰也会掉苞！ 解决方法： 将蟹爪兰放在隔着玻璃的南阳台即可~ 五、月季 1、没有及时修剪 月季长的很快，在生长的过程里，会长出很多的侧枝啊，横生枝条之类的，这种枝条会分散养分，从而导致每根枝条上的养分都不够分化花芽的。 解决方法： 将月季的徒长枝条、细弱枝条、干枯枝条、生病的枝条以及花后枝条全都剪掉！ 2、缺少肥料 开花对于月季来说，是一件非常消耗养分的事情，如果不能及时补充肥料，月季不能积攒足够的营养，当然就没法开花了~ 解决方法： 一般10天就要施1次充分腐熟的稀薄饼肥，在月季的生长旺季则是要1周1次哦~ [图片]六、茶花 1、温度太低 茶花要在10~15度左右的温度才能产生花芽，如果温度达不到，花蕾就孕育不出来，或者是孕育出来花蕾了，结果温度一降低，全都掉了…… 解决方法： 冬天的时候把茶花放在室内养护，放在南阳台等地方，而且不要随便挪动，总是挪动，茶花会死。 2、湿度不够不通风 茶花喜欢湿润的环境，养殖的时候，最好每天往茶花的叶子上喷水，增加空气湿度，同时也要每天开窗通风，一直闷着的话，也会造成落蕾哦~ [图片]七、茉莉 1、光照不足 茉莉喜光，非常喜光，如果光照不足，花芽无法分化，自然就不开花了。 解决方法： 有条件的进行露养，没条件的就放在南阳台上，一定要光照充足才行！ 2、土壤偏碱 茉莉是南方花卉，喜欢微酸性的土壤，北方花友养护的时候可能会忽略掉这一点，殊不知这就是你家茉莉不开花的原因啊！ 解决方法： 每次浇水的时候加入1~2滴醋，或者用硫酸亚铁进行灌根，比例是1:1000，大概1周1次即可。 [图片]八、菊花 1、光照太多 菊花是短日照植物，每天的日照时间太长，菊花的花芽就不会分化，而且灯光也是光，也会影响到的。 解决方法： 如果晚上家里非常亮堂的话，最好给菊花关小黑屋，或者是直接进行露养。 2、肥料不足 开花就要消耗营养，不施肥还想开的好，世界上就没这么容易的事儿~ 解决方法： 从立秋之后，1周施1次稀薄的骨片酱渣水，等到含苞待放的时候，再加1次磷酸二氢钾溶液，比例是1:1000，开花会更艳丽哦~ [图片]九、桂花 1、时间不够 播种繁殖的桂花，10年左右才能开花；嫁接、压条、分株等方法繁殖的桂花，一般次年即开花；扦插的桂花，一般4年才开花。 解决方法： 所以想想你的桂花是怎么繁殖的，如果是扦插的，先等4年再说吧~ 2、肥料不足 没有营养物质，桂花就是想开花也是有心无力呀，所以亲爱的花友们，一定要给桂花施肥！ 解决方法： 桂花喜猪粪。施肥从春天就要开始了，4～5月期间，10～15天施1次，6～7月期间，7～10天施一次，8月初施最后一次，一般这样，桂花就能开出一大团一大团的花来了！ 一般城市里没有猪粪，可用腐熟的饼肥液代替哦，如果能弄到猪粪的话，还是建议先用猪粪。 3、土壤不合适 桂花也是喜欢微酸性的土壤，盆土过碱，会影响桂花的正常生长，就更不要说开花了~ 解决方法： 一般盆栽可用腐叶土+沙壤土，按照1:1的比例进行配置。也可以在平时浇水的时候加入2~3滴醋或者是硫酸亚铁~ [图片]十、杜鹃 1、缺少磷钾肥 杜鹃不开花的主要原因是缺少磷钾肥，磷钾肥才是促进杜鹃形成花芽的主力。 解决方法： 在花芽分化期，及时补充磷钾肥，比如草木灰（含有钾肥）、蛋壳（磷肥）、腐熟的动物碎骨（磷肥）等等，在花盆中埋入适量，很快就能开花啦~ 2、浇水太多 排水不良，过于湿润，会引起杜鹃叶子枯黄等一系列的问题，从而导致无法孕育花蕾。 解决方法： 配土一定要疏松透气，可以使用腐熟细松针土+粗沙，不要用粗长的松针，比例是4:1。 同时浇水也要注意，一般室内养的杜鹃是3~5天浇水1次，保持土壤微微湿润就可以。 [图片]十一、兰花 1、光照不足 兰花虽然不喜欢烈日暴晒，但是也不意味着过于荫蔽，如果长期将兰花放在室内荫蔽的地方，光合作用不够，肯定是没法开花的。 解决方法： 最适合放置兰花的地方就是靠南的窗户和阳台，而且要时常打开窗户通风哦~ 2、肥水管理不当 兰花的浇水是一大学问，如果浇水做不好，很容易就会造成烂根等问题，就更不用说开花了。 解决方法： 浇水一定要见干见湿，保持土壤微微湿润即可。 兰花需要施薄肥，一般半个月施肥1次，每次用稀薄的腐熟豆饼水即可。 [图片]十二、牡丹 1、没有经过春化 牡丹开花之前，必须经过一次低温处理才行，就是在0~10℃的环境中过2~3个月，很多花友到了冬天就把牡丹搬进室内，温度根本达不到，所以牡丹就没法开花。 解决方法： 冬天的时候别把牡丹搬进室内，牡丹能耐零下30度左右的低温，你的担心都是多余的！ 2、肥水不当 牡丹开花需要充足的养分，开花前施肥一定要足，大约1周1次充分腐熟的饼肥。 解决方法： 牡丹孕蕾期需控制浇水，抑制枝叶生长。如果浇水过多，则易引起叶片徒长，就会出现只长叶子不开花的现象。 [图片]只要掌握了正确的方法， 想让花开不断， 还是很简单的哦！

Scientific Name Crocus sativus L. [图片]Common Names Saffron, Saffron Crocus, Autumn Crocus Synonyms Crocus officinalis, Crocus orsinii, Crocus pendulus, Crocus setifolius, Geanthus autumnalis, Safran officinarum Scientific Classification Family: Iridaceae Subfamily: Crocoideae Genus: Crocus [图片]Flower Color: Lilac-purple Bloom Time: Autumn Description Crocus sativus is a perennial plant, up to 6 inches (15 cm) tall. Each corm produces several upright, cup-like, lilac-purple flowers with dark purple veins that bloom in early to mid-autumn. Each flower has three long style branches tipped with reddish-orange stigmas. Flowers close at night and open up in the morning. Basal, grass-like leaves appear slightly prior to bloom. [图片]How to Grow and Care In areas where Saffron Crocus are reliably hardy—USDA Zone 6 through 8 in the South, 6 through 9 in the West—you should plant the corms as soon as you receive them. Saffron Crocus do best in full sun and well-drained soil that is moderately rich in organic matter. Ideally, the site should be relatively dry in summer, when the corms are dormant. Plant the corms 4 inches (10 cm) deep and 4 inches (10 cm) apart. If gophers, mice, or voles are a problem in your garden, plant the corms in containers or line the bed with hardware cloth or a similar wire mesh. Flowers generally come up 6-8 weeks after planting, although occasionally they wait until the 2nd fall to appear. Bloom lasts about 3 weeks. The grass-like leaves may emerge either with the flowers or soon after they appear. Sometimes they wait until the following spring. In either case, the leaves persist for 8-12 weeks, then wither and vanish, leaving no trace of the corms below until the flowers appear again in fall. It’s not a bad idea to mark the area where you’ve planted your corms, so you don’t inadvertently dig them up while planting something else. Origin Native to southern Europe and Asia.
