人家MM说，只要每年重复开花就好了。
用籽繁殖，每年等长出花了，恐怕已是飘雪花的时候了。

花本身都很大我打算每年花期结束入冬前修剪枝叶全部剪短到1FT

人家MM说，只要每年重复开花就好了。

这种种法需要在秋天时埋种子或者是冬天在室内培育夏天移植到户外

Sean Mama · 2011-06-08

花开过后就要马上剪枝，不要让养分都供给结种子。特别是茎类的，象郁金香，开过花后马上剪掉，把养分留在茎部。

罪恶天使 · 2011-06-08

不是很明白楼上的意思把养肥留在茎部有什么特殊意义么？养分不就是盼着多长几个种子等开花么？

<h1>Ten Low Maintenance Perennials</h1><hr size="1" />

The plants suggested here are hardy, easy to grow, beautiful and very rarely have insect or disease problems.

<h3>Achillea filipendulina (Asteraceae or Compositae)</h3>

Fern-leaf Yarrow

<table cellspacing="1" cellpadding="2" align="right">
<tr>
<th valign="middle" width="264"><img src="perennials_en-1.jpg" alt="Achillea filipendulin" border="0" width="250" height="188"/>
</th></tr>
<tr>
<td valign="middle" width="264">Achillea filipendulina
</td></tr></table>

These clump-forming Yarrows bloom in early summer. The leaves are fern-like and aromatic. The flowers form flat-topped heads normally in shades of yellow though there are some cultivars that are pink, peach or red. Cultivars vary in height from a few inches to five feet tall and are used in perennial borders and meadows. After they bloom, cut the stems down to the ground. 

<ul><li> Grow them in a sunny spot in evenly moist, fertile soil. </li>

<li> They do not need fertilizing, instead mulch annually with compost to maintain soil moisture and fertility. </li>

<li> They may get powdery mildew disease (August usually) when grown in poor, dry soil. </li>

<li> Divide the clumps every few years otherwise they become too large</li></ul>

<h3>Artemisia sp. (Asteraceae or Compositae)</h3>

Artemisia, Wormwood, Silver-Lady Lavender, Silver or White Sage

<table cellspacing="1" cellpadding="2" align="right">
<tr>
<th valign="middle" width="264"><img src="perennials_en-2.jpg" alt="Artemisia sp." border="0" width="250" height="163"/>
</th></tr>
<tr>
<td valign="middle" width="264">Artemisia sp.
</td></tr></table>

Artemisias are easy to grow in a hot, dry, sandy location and like many heat and drought-tolerant plants most have silver-grey foliage (fernlike, finely cut, silvery-white leaves with a hairy coating covering the leaf surface). The small, inconspicuous flowers are wind pollinated. There are many cultivars that differ in height, intensity of silver colour and leaf form. There are many species in cultivation, including Absinth, and the culinary herb Tarragon. Artemisia schmidtiana 'Silver Mound' is the most popular one used in Ottawa, it forms a 30 cm (12&quot

x 30 - 45cm (12-18&quot

mound, used as an edging plant in the border. 

The leaf colour helps to tie the border together, adds an attractive contrast to dark green plants and, compliments pink, red, bronze and blue plants in the garden. They are also used in large mass plantings

<ul><li> Needs full sun to keep the colour strong and the growth sturdy. </li>

<li> Grows readily in any soil that is not wet, but prefers a dry, sandy, soil. </li>

<li> Should not be fertilized as plants become more greenish and spread too rapidly. </li>

<li> Regular division in spring or early September helps keep the spreading plants in check. </li>

<li> Cut 'Silver mound' back to 5cm (2&quot

when it begins to bloom in mid to late June otherwise it flops open.</li></ul>

<h3>Astilbe (Saxifragaceae)</h3>

Astilbe

<table cellspacing="1" cellpadding="2" align="right">
<tr>
<th valign="middle" width="264"><img src="perennials_en-3.jpg" alt="Astilbe" border="0" width="250" height="333"/>
</th></tr>
<tr>
<td valign="middle" width="264">Astilbe
</td></tr></table>

Astilbes originate in China and Japan but there has been a great deal of hybridization since the 1920's. Astilbes are considered the Queen of Flowers for moist shade, they are very low maintenance and free from problems. They produce dense, weed-proof groundcover and attractive flowers. Spike-like or soft, feathery, plume flowers rise above lacy dark green leaves; the many cultivars provide a long blooming time. Choose plants by size, flower colour and shape, and blooming time. 

A. x arendsii: blooms from June- August, heights range from 55 - 100cm ( 22" - 3') flowers are red, pink, cream, white or lilac,

A. chinesis: this ground covering Astilbe blooms August - Sepember, height is 30 cm (12&quot

, flowers are pink, salmon, lavender, purple, and magenta.

A. glaberrima saxatilis: a rockgarden plant at 10 - 20 cm (4 - 8&quot

, blooming in July - August, shell-pink flowers

<ul><li> Partial shade in ordinary moist soil - full sun in very moist soil </li>

<li> Fertile, evenly and continuously moist soil </li>

<li> Top-dress with well-rotted manure/compost (2.5 - 5 cm) every fall </li>

<li> Divides easily in spring, as the new growth appears, plants can be lifted and divided or moved even in flower (if they are well watered)</li></ul>

<h3>Echinacea purpurea (Asteraceae or Compositae)</h3>

Purple Coneflower

<table cellspacing="1" cellpadding="2" align="right">
<tr>
<th valign="middle" width="314"><img src="perennials_en-4.jpg" alt="Echinacea purpurea" border="0" width="300" height="151"/>
</th></tr>
<tr>
<td valign="middle" width="314">Echinacea purpurea
</td></tr></table>

This Eastern North America native plant grows in grassy areas and open woodland meadows. The herbal remedy Echinacea comes from E. angustifolia. Flowers bloom above the rough, course leaves, which form a dense clump. The daisy flower head has a prominent hard, bristly, brown cone surrounded by drooping purple-pink petals. Echinaceas bloom from July - September. Purple Coneflower is an important plant for the summer border and for naturalizing meadows and wild-gardens. It grows to 75 - 120 cm (30 - 48 &quot

tall.

Rudbeckia, Black-eyed Susans, Cone-flower or Gloriosa Daisy, are similar to Echinacea in form, and requirements except that the bloom is bright yellow instead of purple. 

<ul><li> Full sun </li>

<li> Ordinary well-drained garden soil, drought-tolerant </li>

<li> No fertilizer needed </li>

<li> Staking is needed in very rich, moist soils </li>

<li> Deadhead old flowers, seed heads can be use in dry floral arrangements. </li>

<li> Divide the clumps in spring. Seeds germinate easily and grow quickly.</li></ul>

<h3>Euphorbia polychroma (or E. epithymoides) (Crassulaceae)</h3>

Cushion Spurge

<table cellspacing="1" cellpadding="2" align="right">
<tr>
<th valign="middle" width="264"><img src="perennials_en-5.jpg" alt="Euphorbia polychroma" border="0" width="250" height="129"/>

<td valign="middle" width="264">Euphorbia polychroma
</td></tr></table>

It is in the same family as Poinsettia and in fact it is the coloured bracts that give it, its bright greenish-yellow colour in late spring (in Ottawa when the tulips bloom). In the spring it grows rapidly into a neat mound about 30 - 45 cm (12 - 18&quot

, high having smooth, 5 cm (2&quot

long leaves. The stems grow a little longer after the flowers fade forming a green mound, which turns red in the fall. All spurges produce a milky sap from broken leaves or stems, which may be irritating to the skin. Interplant it with spring flowering bulbs and perennials, at the base of a rock garden or with shrubs. Other spurges grown in Ottawa are:

E. griffithii: 50 - 90 cm (20 - 36&quot

flame-orange bracts turn red in fall. 

E.myrsinites: a succulent, prostrate, 15 - 20 cm (6 - 8&quot

, blue leafed, evergreen rock garden plant with yellow coloured bracts in spring.

<ul><li> Full sun </li>

<li> Well-drained to dry soil, very drought-tolerant </li>

<li> Avoid fertilizing otherwise plants become floppy </li>

<li> Careful division in early spring (try to avoid damaging the fleshy roots)</li></ul>

<h3>Ornamental Grasses (Poaceae or Graminae)</h3>

<table align="right">
<tr>
<th valign="top" width="264"><img src="perennials_en-6.jpg" alt="Ornamental Grasses" border="0" width="250" height="333"/>

<tr>
<td valign="top" width="264">Ornamental Grasses
</td></tr></table>

The grass family contains about 6,000 species. The cereal crops are Grasses. They are highly evolved, wind-pollinated plants used for their long, thin foliage (may be brightly coloured) and upright form. The look and sound when they blow in the wind is very appealing. In the late summer they have feathery flowers at the top of the stems, which remain for months. Grasses range from 15 cm - 4 m (6" - 4 yd.) tall. Depending on size they can be specimen plants, container plants, groundcovers, mass planted or accents in the garden. Control their width to about 2/3 height. Clump forming grasses are not invasive. Grasses create a casual garden style, having full sensory impact in late summer and fall. Visit the Music Garden in Toronto's Harbour front in the fall.

<ul><li> Full sun </li>

<li> Ordinary garden soil. Most species are tolerant of dry soil but some are adapted to wet soil. </li>

<li> Does not need fertilizer </li>

<li> If it is grown for winter effect, cut them down in very early spring before new growth starts. Cut other grasses in late fall. </li>

<li> Best to divide in the spring just as the new growth starts, but many grasses can be divided in early September. </li>

<li> Hardy to Zones 3 - 5 (cultivar dependant) </li></ul>

</th></tr>
<tr>
<td valign="middle" width="264">Hemerocallis hybrids
</td></tr></table>

Daylilies have been popular since the 1930's. In the spring, grass-like leaves emerge forming a clump. The leaves have a keel down the length in the middle. The leaves range in length from 30 - 60 cm (1 to 2') and are 2.5 cm (1&quot

wide. Open, lily-like flowers bloom from late May - late August, with the peak period in July. The flowers open one at a time from the top of a leafless stem, each lasting one day. Daylilies come in a wide range of colours: yellow, orange, peach, apricot, and rust. They are grown in the border, as a groundcover, mass planted in hard to look after areas, and in large containers. The dense foliage will smother many weeds.

<ul><li> Full sun, (some pale colours prefer afternoon shade). </li>

<li> Well-drained, ordinary soil. High organic content recommended. Tolerant of drought and neglect. </li>

<li> No fertilizing needed </li>

<li> Divide anytime, best in early spring or early fall </li>

<li> Cut back the flower stems after blooming </li>

<li> Cut foliage down in the fall</li></ul>

<h3>Ligularia sp. (Asteraceae or Compositae)</h3>

Ligularia or Golden Ray

<table cellspacing="1" cellpadding="2" align="right">

</th></tr>
<tr>
<td valign="middle" width="264">Ligularia sp.
</td></tr></table>

Ligularia is a long-lived, easy-to-care-for plant when grown in cool, moist, fertile soil. Large glossy leaves mound over the soil at the base of the plant. They bloom yellow/orange daisy flowers singly or on spikes, in late summer - early fall. These tall, dramatic plants can be 3 feet across, more in rich soil. Large leafed plants create a bold tropical effect. Plant them as accents, specimens, beside ponds and streams. They always attract attention!

<h4>L. dentate: </h4>

'Desdemona': Leaves dark purple underneath, bright orange daisy-like flowers. 
Grows to 90 - 120(3 - 4'). 
'Othello': Leaves brownish, blooms slightly earlier than 'Desdemona'. 
Grows to 90 - 120 cm (3 - 4'). 

<h4>L. stenocephala: </h4>

Leaves deeply toothed, small yellow flowers on narrow, glossy purple-black, 
upright flower stems. 
Grows to 120 - 180 cm (4 - 6'). 
Cultivars include 'The Rocket' and 'Sungold'

<h4>L. wilsoniana: </h4>

Tall spikes of yellow flowers in mid-summer. Grows to 150 - 180 cm (5 - 6')

<ul><li> Full sun in wet soil, light shade is better in hot areas where the soil is not wet. </li>

<li> Best in a rich, moist soil, but will grow quite well in regular soil </li>

<li> No need for fertilizing. </li>

<li> Spring division when needed (seldom). Plants take a couple of years to establish</li></ul>

<h3>Paeonia hybrids (Paeoniaceae)</h3>

Peonies have been cultivated in China for centuries. In the late 1700's they were introduced to the rest of the world and have never lost their popularity. They are beautiful, easy to grow and very long lived. Peonies are a focal point in the border when they bloom, and after they remain an attractive shrub-like mounding plant. The Bomb and Double types are the most commonly used Peonies but because the flower heads are very heavy they need staking. Japanese, Anemone and Semi-double types are easier to care for in the garden because the flowers stay up without staking.

Peonies form large, bushy, mounding plants, 75 - 100 cm (30 to 40&quot

x 100cm (3'), with shiny, divided leaves that change colour in the fall to yellow or red. Single flowers form at the top of the stems, (above the mounded leaves) with other buds growing below but usually they do not open. Peonies come in pink, red and white and bloom from late May to mid-June. Ants eat the sticky material on the bud, but this does not help the flowers to open. 

Hot humid weather increases the possibility of Botrytis blight. Cut out the affected leaves and stems (they become brown and die back). This is not a common problem and is a sign that the plants are not growing in proper conditions

<ul><li> Full sun or light shade. </li>

<li> Deep, fertile, well-drained loamy soil </li>

<li> An application of sulphate of potash in early spring will help keep the flower stems stronger. </li>

<li> Divide the woody crown, (10 - 15 years) in early fall (late August early September in Ottawa). Pieces should have 2 or 3 buds (pips, or eyes) and a good size piece of root to do well. When planting new plants it is important to place the buds at the same depth in the soil as they were at before. Deeper planting will delay flowering. It may take 2 or 3 growing seasons for peonies to develop and flower well again. </li>

<li> Deadhead flowers to create a neat dome shaped plant that will be a background to other flowers. </li>

<li> Staking is often needed for double cultivars. It should be done before flowering in early spring otherwise the stems may fall and break </li>

<li> Cut the stems down to a few cm in late fall and top-dress with 2.5 - 5 cm (1 - 2&quot

of well-rotted compost or manure.</li></ul>

<h3>Sedum sp. (Crassulaceae)</h3>

Stonecrop

<table cellspacing="1" cellpadding="2" align="right">

</td></tr></table>

Sedums are succulent, plants adapted to dry conditions. The thick fleshy leaves store water. Low mat forming species often have a wide variety of leaf and flower colour, and are excellent for rock gardens, or groundcovers even on hot, dry slopes. Taller species have beautiful fall colour, attract pollinators and give wonderful colour in borders. All sedums are nice in containers. 

S. acre: 8 cm (3&quot

, yellow leaves in spring, turning green, followed by yellow flowers in late summer 
S. album: 10 cm (4&quot

, green leaves turn red-maroon in fall, flowers either white or pink 
S. anacampseros: 15 - 25 cm (6 - 10&quot

, round blue leaves, purple flowers in late summer 
S. cauticola: 10 cm (4&quot

, blue leaves, pink flowers in late summer-late fall 
S. cyaneum: 10 cm (4&quot

globe shaped green leaves, yellow flowers in summer. Native plant. 
S. ewersii: 15 cm (6&quot

blue round leaves, rose pink flowers in late summer 
S. kamtschaticum: 15 cm (6&quot

Moist soil. Scalloped leaves, yellow or gold flowers in summer 
S. oreganum: 15 cm (6&quot

Thick leaves, yellow flower. Native plant 
S. reflexum: 15 cm (6&quot

Blue needle-like leaves, yellow flowers. 
S. sieboldii: 15 - 20 cm (6 - 8&quot

,blue scalloped leaves, pink flowers in late fall. 
S. spathulifolium: 10 cm (4&quot

, rosette of fleshy leaves, yellow flowers in summer. 
S. spurium: 15 cm (6&quot

mat forming, often variegated leaves, with pink, red or white flowers. 
S. telephium x spectabile 'Herbstfreude': 45-60 cm (18-24&quot

This is the most popular border sedum. Autumn Joy sedum flowers are small but are in large flat-topped heads above the foliage, they start off cream-green and gradually turn from pink, to a deep, bronzy-mahogany red from September - October.

<ul><li> Full sun, (partial shade for some cultivars) </li>

<li> Well-drained, ordinary soil. Very drought-tolerant </li>

<li> No fertilizer needed </li>

<li> Divide anytime, best in early spring. Very large plants that need staking should be divided </li>

<li> Cutting back stems in spring if you like to see the flower heads poke through the snow</li></ul>
