Family - Rosaceae
Stems - Multiple from base, spreading to ascending or erect, herbaceous, to +45cm long, villous, branching near apex.
Leaves - Alternate. Basal leaves toothed, typically unlobed but also 3 to 5-lobed, crenate-serrate, petiolate, to +25cm long. Lower cauline leaves pinnately divided, serrate, pubescent above, pubescent typically on veins below. Upper cauline leaves typically 3-lobed (lobes often divided further), serrate, ciliate-margined, glabrous to sparse pubescent above, pubescent on veins below, dull green above, silvery-green below. Stipules at base of petioles serrate, with same pubescence as leaf blade.
Inflorescence - Loose cymes terminating stems. Peduncles and pedicels with sparse villous pubescence mostly near base or glabrous.
Flowers - Petals yellow to yellow-orange, 5, to 3mm long, clawed, glabrous. Hypanthium campanulate, 2-3mm broad, 1.5mm tall (long), glabrous. Stamens +20, borne at edge of hypanthium, persistent in fruit. Filaments to 1mm long. Anthers yellow, .6mm in diameter. Sepals 5, acute to acuminate, 2mm long in flower, ciliate-margined, sharply recurved, persisting and elongating below fruit. Ovary stalked. Stalk elongating in fruit. Achenes glandular pubescent, beaked with persistent styles and stigmas.
Flowering - April - June.
Habitat - Moist ground, thicket edges, waste ground.
Origin - Native to U.S.
Other info. - This is a common little plant which can bloom fairly early in the season. The growth habits can be variable from erect to nearly prostrate. The flowers are very small, as you can see from the pics, and it is common for the petals to be fewer than 5. The achenes have a "hinged" barb which is the persistent style and stigma. The basal leaves are often missing or dying off by the time the plant is in heavy flower.

¿Qué luz necesitan? Lugar con mucha luz, aunque el sol directo todo el día podría provocar quemaduras en especies delicadas. Lo mejor es sol una parte del día, al menos unas 5 ó 6 horas de sol, de mañana o de tarde.
Cactus grandes toleran más sol que los pequeños.
¿Qué temperatura necesitan?
Dependerá de las especies, pero en general, si la temperatura baja de +5ºC, muchas Suculentas, sobre todo las que provienen de zonas tropicales, pueden morir.
Los cactus en su hábitat natural, por las noches, las temperaturas alcanzan algunos grados bajo cero.
Cuando el termómetro baje de 10º-15º C es muy importante conservar el substrato de las macetas totalmente seco. Por tanto, si tienes cactus en macetas en el jardín, es aconsejable disponer de un sitio que no se mojen con la lluvia, una zona cubierta con algún material traslúcido como un techo de plástico. Además el techo resguarda del frío, aunque en climas con heladas fuertes no es suficiente protección y hay que meter dentro de casa o en un invernadero.
¿En qué consiste la invernada?
Para garantizar la floración de los cactus, conviene dejar la planta en estado de reposo durante el invierno, reduciendo al mínimo los aportes de agua y nada de abono.
Hazlas invernar dentro de casa en un sitio fresco y luminoso, por ejemplo el dormitorio. Por ejemplo, la pequeña Lobivia silvestrii (o Chamaecereus silvestrii) sólo florecerá si ha soportado un golpe de frío durante el invierno.
Una vez terminado el reposo, evita sacar las plantas de golpe al sol tras pasar el invierno a cubierto. Si ha estado en penumbra corre el riesgo de quemaduras irreversibles. Finalmente, no debes retomar la fertilización hasta avanzada la primavera.
¿Cómo debe ser el substrato para cactus y Suculentas?
Venden unos preparados que se les suele llamar "Sustrato para cactus". Sólo hay que tener en cuenta que vienen poco abonados por lo que se les debe añadir fertilizantes minerales.
La otra opción es hacerte tu propia mezcla. Lo fundamental es que el substrato nunca quede encharcado. Se recomienda que el 50% de la mezcla sea arena de río lavada y gruesa, el otro 50% entre turba negra y perlita. Se debe añadir a este sustrato abono, por ejemplo, uno de lenta liberación.
La mencionada arena de río lavada y gruesa no es fácil de encontrar en el comercio, pero es la ideal. La arena de la construcción no es recomendable por su contenido alto en caliza, sales y poca aireación al tener granos gordos y finos.
Para cactáceas epifitas, las que brotan en los árboles de las selvas tropicales, usa un sustrato convencional para plantas de interior.
Finalmente, ciertas plantas crasas (Ágaves, Euforbias, Compuestas y Aizoáceas) son bastante indiferentes en cuanto a la composición de la mezcla, con la condición de que drene bien.
Macetas
Para el exterior, donde no podemos controlar el riego en el invierno, conviene que las macetas sean de barro o terracota u otro material transpirable. De esta manera, facilitamos la pérdida más o menos rápida de la humedad del substrato.
No proporciones a la planta una maceta excesivamente grande, ya que ésta acumulará más humedad.
Conviene sustituir tanto en la parte superior como en la inferior de la maceta, dos centímetros de substrato por algún tipo de árido de grano grueso, de unos 10 mm. como mínimo, para evitar la posible podredumbre de la planta. Con un taladro haz varios agujeros más de drenaje a la maceta para facilitar la salida del agua.
Para casa o en invernadero son buenas las macetas de plástico.
Se pueden adornar las macetas con rocas volcánicas, cantos rodados o grava en la superficie.

Family - Brassicaceae
Stems - To +60cm tall, from stout taproot, herbaceous, glaucous above, with stellate and simple hairs below (dense), erect, typically simple.
Leaves - Alternate, sessile, clasping, stellate and simple pubescent. Lowest leaves 5-6cm long, 1.5-2cm broad, oblong, entire. Middle and upper leaves reduced upward, lanceolate. Auricles typically pointed.
Inflorescence - Terminal raceme, compact in flower, elongating in fruit to +30cm tall (long). Pedicels to 3mm in flower, elongating to 1.5cm in fruit, glabrous.
Flowers - Petals 4, pale-yellow, to +/-5mm long. 1.2mm broad at apex, glabrous. Stamens 6. Filaments glabrous, 3mm long. Anthers yellow, .2mm long and broad. Ovary ovoid, 2-valved. Style 1mm long, persistent in fruit and forming beak. Stigma globose.
Fruit - Obovoid silicle tapering at base, to 5mm long, 4mm in diameter, glabrous, many seeded(+/-10). Beak to 2mm long. Valves margined.
Flowering - April - September.
Habitat - Waste ground, disturbed sites, roadsides, railroads.
Origin - Native to Europe.
Other info. - This is an easily identifiable plant which you are not likely to see unless you like to walk railroad tracks. The flowers close and shrivel very quickly on sunny, warm days, so the plant is best viewed when it's overcast. Pulling the plant from the ground is an effort in futility as the taproot is quite large.

Family - Hippocastanaceae
Stems - Woody to 9m tall, with a single trunk or multiple trunks.
Leaves - Opposite, palmately compound, petiolate. Leaflets typically 5, but sometimes 6 or 7, 3-8cm wide, 15cm long, serrate, pubescent below, glabrous above, acuminate. Petiolules to 1cm long.
Inflorescence - Terminal panicle to 20cm long on new season growth. Axis of inflorescence densely pubescent with multicellular hairs. Pedicels pubescent, to 8mm long in flower.
Flowers - Petals 4, pale yellow to creamy whitish, clawed. Claws of upper petals to 3.5mm long, with dense tuft of villous pubescence at apex. Limb of upper petals +1.5cm long, 4mm broad at apex, with reddish spot near base of limb, pubescent. Lower petals with claw to 3.5mm long. Limb of lower petals +1cm long, 8-9mm broad, pubescent. Stamens 7, exserted. Filaments villous, to -2cm long, white. Anthers orange-red, 2mm long. Ovary 6mm long, dense villous at base but glabrous and reddish at apex. Calyx tube to 7mm long, 5mm in diameter, 5-lobed, yellow-green, pubescent. Lobes to 3mm long, obtuse, pubescent. Fruits globose, spiny, 2.5-6cm in diameter. Seeds 2 per fruit, +/-3cm in diameter, shiny, dark brown.
Flowering - April - May.
Habitat - Wooded slopes, ravines, thickets, open, rich woods, also cultivated.
Origin - Native to U.S.
Other info. - This species can be found throughout Missouri but is apparently absent from the extreme southeastern and northwestern corners of the state. The tree is easy to identify because of its palmately divided leaves (which are opposite) and its big inflorescences. The buds are easy to ID in winter also as they are quite large and the tree generally has a widely spreading growth habit. This species deserves to be cultivated more and it grows easily from seed. The fruits of the plant split into 3 parts and the seeds are actually edible. The seeds should be cooked first as they can be mildly toxic if eaten raw.

富贵树的养殖方法和注意事项
种植的时间
栽培最佳时间在10月下旬降霜后或是4月中上旬发芽前进行;移栽时间在春、夏、秋三季均可,移栽时若在生长期需要带土移栽。5月上旬以前或10月中旬以后是引种根最佳时间。
土壤
栽培宜用富含有机质、排水良好、疏松肥沃的壤土或沙质壤土。
浇水
生长时期盆土应保持潮湿,切忌土壤过于干燥,酷夏时期,要经常给叶子喷水,以防过于干燥,会使叶子干枯,但是冬季的盆土不要太过潮湿,同样要经常给叶子喷水,保持也自然湿润。
温度
可耐寒亦可耐热,零下33℃低温,可正常生存;耐热,生长更迅速。
光照
在春、秋两季要每天有3~4小时光照时间,这样可以保持叶子的油绿色泽。夏季和秋季的时候,养护过程中需要进行遮阳,并保证充足的空气湿度和土壤湿度,适时的进行叶面的清洗,会使得植株的生长更加旺盛。
注意事项
富贵树对肥料的要求不高,但每20~25天施肥一次,氮、磷、钾复合肥会使其生长的更加旺盛。富贵树要保持充足的水分,每两天必须浇灌一次,每次浇灌时最好把土全部浇湿润,水分的充裕,可以提高贵树的光合作用。
富贵树名字寓意很好,对净化空气起到很大作用,同时也很容易融合进家居摆设里,适合很多场合。快让富贵树成为你家中的一道迷人的风景线吧。

多年生肉质草本植物,茎粗壮,灰白色,多分枝,叶对生,排列紧密。叶片倒卵形,长10~15厘米,宽5~7厘米,全缘,先端钝圆。叶色淡绿或黄绿,被有浓厚的白粉,因此,看上去呈灰绿色,秋末至初春的冷凉季节,在阳光充足的条件下,叶缘呈红色。小花筒形,黄色,长1.5厘米。原产南非开普省东部和德兰士瓦省。
形态特征
多年生肉质草本植物,茎粗壮,灰白色,多分枝,叶对生,排列紧密。叶片倒卵形,长10~1
5厘米,宽5~7厘米,全缘,先端钝圆。叶色淡绿或黄绿,被有浓厚的白粉,因此,看上去呈灰绿色,秋末至初春的冷凉季节,在阳光充足的条件下,叶缘呈红色。小花筒形,黄色,长1.5厘米。叶色淡绿,上披有一层厚厚的白粉,呈灰绿色,叶缘有一圈红色线条,在冷凉季节,于阳光充足的户外,叶缘会出现渐层的红色色斑。
唐印烂根的原因
唐印烂根,通常是浇水不当引起的。春秋冬夏的四季养护,对于水分的需求是不同的。春秋适宜保持盆土微潮,冬夏适宜保持盆土适当干燥,如果浇水过勤,非常容易烂根。
唐印烂根的后果
唐印烂根,会导致叶片干枯萎缩,皱皱巴巴的,不仅不通透红艳,还像个干瘦的老太太,一点没有唐美人的风采。
严重时,甚至会引起植株死亡。
唐印烂根的补救措施
勤观察,发现植株状态不好,要及时检查根部的情况。
烂根之后,要切掉腐烂的部分,晾晒一到两天,重新栽种。顺便剪除枯萎的叶片,让她在新的盆土里长出更好的叶片。
根部腐烂严重的,可以直接砍头重新扦插,长出一盆新的唐美人来!

量天尺(Hylocereus undatus (Haw.) Britt. et Rose)为仙人掌科量天尺属植物,附生性多浆肉质植物。茎粗壮,深绿色,具三棱。花大形,白色,有芳香,5至9月晚间开放。
原产于美洲热带和亚热带地区,其他热带和亚热带地区多有栽培。中国广东、广西、福建、海南等省区有天然分布。量天尺花朵硕大,且具芳香。宜庭植、盆栽,或作为篱垣植物。
生长习性
喜温暖、空气温暖。宜半阴,在直射强阳光下植株发黄。生长适温25~35℃。对低温敏感,在5℃以下的条件下,茎节容易腐烂。喜含腐殖质较多的肥沃壤土,盆栽用土可用等量的腐叶上、粗沙及腐熟厩肥配制。
一种热带雨林植物,适于高空气湿度、高温及半阴环境,生长适温25~35℃,越冬温度宜在13℃以上,喜含腐殖质丰富、排水良好的肥沃壤土。 宜半阴,在直射强阳光下植株发黄。生长适温25-35℃。
量天尺为什么会烂根
土壤不符合量天尺的生长需要。量天尺对土壤的要求虽然不严,一般的培养土就能良好地生长。但是有一点就是土壤要疏松,透气,排水性要好。否则就会导致量天尺根部呼吸不畅,或是盆内有积水,以致烂根。
施肥不当导致烂根。量天尺施肥要讲究技巧,用肥不能过浓,过量,以免造成肥害而导致烂根。一般以薄施勤肥为佳。冬季休眠期,要停止施肥。因为气温较低时根系生长处于缓慢状态,所施肥料不能被根系所吸收,反而会妨碍根的正常吸收,严重时便会烂根。
浇水过多导致烂根。当量天尺浇水过多时,盆内过于湿润,根部呼吸不畅,容易导致量天尺烂根。
量天尺烂根怎么办
量天尺烂根时必须及时将腐烂的部分削掉,留下健康的部分,重新扦插。将伤口消毒,然后置于阴凉通风处晾晒2~3天,再用消毒过的净沙和花盆扦插。
将量天尺插入沙土里,浇一次透水,此后便要干透浇透,注意不能淋雨。
量天尺重新扦插后,要求放在通风处并接受充分光照。温度保持在25~30℃即可,不要施肥。约在30天至40天,即可长出新的根系。
在平时要注意做好量天尺的日常养护,合理浇水施肥,平时要注意多观察量天尺的生长状况,观察有没有烂根或虫害的情况,及时发现病变并作出应对措施。
