Scientific Name Convallaria majalis L.
Common Names Lily of the Valley, American Lily of the Valley, European Lily of the Valley, Our Lady’s Tears, Mary’s Tears, May Lily, May Bells Synonyms Convallaria keiskei, Convallaria latifolia, Convallaria linnaei, Convallaria mappii, Convallaria transcaucasica, Lilium-convallium majale, Polygonatum majale Scientific Classification Family: Asparagaceae Subfamily: Nolinoideae Genus: Convallaria
Flower Color: White Bloom Time: Late spring Description Convallaria majalis is a rhizomatous perennial up to 12 inches (30 cm) tall, forming extensive colonies. The stem grow with one or two leaves up to 10 inches (25 cm) long. Flowering stems have two leaves and a raceme of 5 – 15 flowers on the stem apex. The sweetly scented flowers are white (rarely pink), bell-shaped, up to 0.4 inch (10 mm) in diameter. Flowering is in late spring. The fruit is a small orange-red berry up to 0.28 inch (7 mm) in diameter.
How to Grow and Care Despite its temperamental reputation, Lily of the Valley is easy to grow if you buy it ready potted in spring. Dried crowns take ages to get going and do not always survive and it may also prove difficult to establish chunks supplied by friends. In both cases, pot up the crowns separately in loam-based compost, water well and allow them to establish for a year before planting out. (You can do the same in midwinter, forcing the crowns for an early show indoors.) At planting time, work in some humus, good garden compost or, even better, leafmould. Spread out any underground stems and cover with just a couple of inches of the planting mixture. Mulch well with leafmould. If you find that flowering is poor, an occasional dose of high-potash organic liquid feed may help. Origin Native throughout the cool temperate Northern Hemisphere in Asia, Europe and in the southern Appalachian Mountains in the United States.

Common Names Greentip Lily, Greentip Kaffir Lily, Greentip Forest Lily, Drooping Clivia, Cape Clivia, Bush Lily Synonyms Haemanthus cernuiflorus, Himantophyllum aitonii, Imatophyllum aitonii, Imatophyllum maximum Scientific Classification Family: Amaryllidaceae Subfamily: Amaryllidoideae Tribe: Haemantheae Genus: Clivia
Flower Color: Orange Bloom Time: Spring and summer Description Clivia nobilis is an evergreen, rhizomatous perennial up to 2 foot (60 cm) tall, that forms tight clumps of strap-shaped, dark, non-glossy, green leaves with slightly serrated edges and a rounded tip. Arranged in an umbel the long-blooming, tubular, orange flowers in spring and summer droop downward and are followed by marble sized red berries.
How to Grow and Care Clivia plants require partial to full shade and fast-draining loamy soils to produce healthy growth. Spread a 1-inch (2.5-cm) layer of mulch around the Clivia plant with a rake. Keep the mulch 4 to 6 inches (10 to 15 cm) from the base of the plant to avoid rot. Water the Clivia plant when the top 1 to 2 inches (2.5 to 5 cm) of soil become dry during the active growing season using a garden hose. Keep the soil moist but never soggy. Never water the Clivia to the point that there is standing water on the soil’s surface. Reduce watering in the late fall and winter months when the plant enters dormancy. Water dormant Clivia plants when the top 3 to 5 inches (7.5 to 12.5 cm) of soil becomes dry. Fertilize the Clivia with a 6-6-6 nitrogen, phosphorous, potassium formulation slow-release fertilizer every three months during the growing season. Apply at a rate of 1 teaspoon per square foot of soil. Spread the fertilizer in a ring around the Clivia plant, keeping the granules 12 inches (30 cm) from its base.

Scientific Name Clematis armandii Franch.
Common Names Evergreen Clematis, Armand Clematis Synonyms Clematis armandii var. armandii, Clematis biondiana, Clematis ornithopus Scientific Classification Family: Ranunculaceae Subfamily: Ranunculoideae Tribe: Anemoneae Genus: Clematis
Flower Color: White Bloom Time: Spring Description Clematis armandii is a flowering climbing plant up to 20 feet (6 m) tall. It bears fragrant, up to 2.4 inches (6 cm) across, white flowers in spring on the previous year’s growth. Its dark green leaves droop to create a textured look, and it serves well as a screen.
How to Grow and Care Clematis vary in their need for pruning. Some types flower on last year’s vines, so you want to avoid cutting them to the ground in the spring. Others flower on current-year vines, so they don’t mind being cut to the ground each year. Rather than driving yourself crazy trying to keep track of the ideal pruning technique for each cultivar, try this common-sense approach: leave the prior year’s growth in place until mid-spring. Begin pruning only when you can see which vines are dead and which ones are starting to leaf out. A happy Clematis plant puts out an amazing amount of flowers and foliage. Feed your plants well to keep them healthy and vigorous. In early spring, surround the plant with a shovelful of compost and a handful of granular organic fertilizer. Feed again, once or twice during the growing season, with a water-soluble organic fertilizer. Origin Native to much of China (except the north and extreme south) and northern Burma.

Flower Color: Purple to white Bloom Time: Late June to August Description Cirsium arvense is an erect, perennial herbaceous plant, up to 4 feet (1.2 m) tall with an extensive creeping rootstock and ridged and hairy stems. The leaves are lance-shaped, irregularly lobed, up to 6 inches (15 cm) long with weakly to strongly prickled margins. The flowers are purple to white, up to 1 inch (2.5 cm) long and 0.5 inch (1.3 cm) across. Flowering occurs in late June to August. The seeds are called achenes, up to 1.5 inches (3.8 cm) long and have a feathery pappus.
How to Grow and Care The seeds of Cirsium can be sown in either autumn or after the last frost of spring. They should be sown at a depth of 0.12 inch (3 mm). If grown indoors first then Cirsium takes about 2 to 3 weeks to germinate at a temperature of 70 to 75 degrees Fahrenheit (21 to 24 degrees Celsius). The seedlings should be planted out in early spring, when it is still possible to get a frost with a spacing of about 2 feet (60 cm). Cirisium thrives in full sun and poor, average or reach soil that is moist but well drained. Plants require little care, but deadheading limits their tendency to self-sow. they generally self-sow only in moderation and unlike weedy thistles, the seedlings are easy to pull up. Use Thistles in mixed beds, herb gardens or meadowlike plantings. Origin Native throughout Europe and northern Asia, and widely introduced elsewhere.

Scientific Name Cichorium intybus L.
Common Names Chicory, Common Chicory, Blue Daisy, Blue Dandelion, Blue Sailors, Blue Weed, Bunk, Coffeeweed, Cornflower, Hendibeh, Horseweed, Ragged Sailors, Succory, Wild Bachelor’s Buttons, Wild Endive, Belgium Endive, Witloof Synonyms Cichorium balearicum, Cichorium byzantinum, Cichorium byzantinum, Cichorium caeruleum, Cichorium cicorea, Cichorium commune, Cichorium cicorea, Cichorium commune, Cichorium divaricatum, Cichorium glabratum, Cichorium glaucum, Cichorium hirsutum, Cichorium illyricum, Cichorium officinale Scientific Classification Family: Asteraceae Subfamily: Cichorioideae Tribe: Cichorieae Subtribe: Cichoriinae Genus: Cichorium
Flower Color: Blue Bloom Time: July to October Description Cichorium intybus is a bushy, perennial plant. The stem is a groved, tough and more or less hairy, up to 40 inches (1 m) tall. Leaves are lanceolate, stalked, and unlobed. The flowers are usually bright blue, rarely white or pink, toothed at the ends, and up to 1.6 inches (4 cm) wide. It flowers from July until October.
How to Grow and Care Seeds can be started indoors five to six weeks before they are moved outdoors. In warm climates, sowing outdoors or transplanting occurs September through March. Planting Chicory in cooler climates should be done three to four weeks before the danger of frost has passed. Sow Chicory seeds 6 to 10 inches (15 to 25 cm) apart in rows that are 2 to 3 feet (60 to 0) apart. You can always thin the plants if they crowd each other but close planting discourages weeds. The seeds are planted ¼ inch (6 mm) deep and thinning is done when the plants have three to four true leaves. You can also sow a crop for fall harvest if you choose a variety that has an early maturation date. Planting Chicory seed 75 to 85 days before anticipated harvest will ensure a late crop. Chicory plants that are to be forced for blanched leaves will need to have the roots dug up before the first frost. Cut the leaves to 1 inch (2.5 cm) and store the roots for three to seven weeks in the refrigerator before forcing. Plant the roots individually after chilling to force the leaves to grow in a tight, blanched head. Origin Native to Europe, and in North America and Australia.

Scientific Name Chelidonium majus L.
Common Names Celandine, Great Celandine, Greater Celandine, Tetterwort, Nipplewort, Swallowwort Synonyms Chelidonium cavaleriei, Chelidonium dahuricum, Chelidonium grandiflorum, Chelidonium haematodes, Chelidonium laciniatum, Chelidonium murale, Chelidonium olidum, Chelidonium quercifolium, Chelidonium ruderale, Chelidonium umbelliferum Scientific Classification Family: Papaveraceae Subfamily: Papaveroideae Tribe: Chelidonieae Genus: Chelidonium
Flower Color: Yellow Bloom Time: Late spring to summer Description Chelidonium majus is a perennial herb, up to 3.9 feet (1.2 m) tall. The leaves are pinnate with lobed and wavy-edged margins, up to 11.8 inches (30 cm) long. The flowers consist of four yellow petals, each up to 0.4 inch (1 cm) long, with two sepals. The flowers appear from late spring to summer in umbelliform cymes of about 4 flowers.
How to Grow and Care Greater Celandine will grow in almost any soil except waterlogged but it does like a reasonable amount of water. Ideal plant for part or full shade but it will grow in full sun in lower zones (6 and 7) provided it has moisture. Prefers a rich woodland soil in semi shade with decent moisture. It is an excellent choice for growing on partially shaded walls or in rock gardens provided there is a pocket of soil to establish its roots. It is a short lived perennial but it will self seed in suitable locations, sometimes aggressively and will take over thin woodland areas if left alone. Germination can be slow and erratic with some seeds taking up to twelve months to sprout. Can be sown in place in early spring or late fall. If choosing this approach keep weeds in the area to a minimum to allow seeds time to germinate and plants to establish. Once the first ones are established they often self seed and proliferate, but this can take several years to achieve. Seeds and also be started in pots. Origin Native to Europe and western Asia and introduced widely in North America.

How to Grow and Care Madagascar Periwinkle is native to Madagascar but is cultivated and naturalized in most of the tropical world and in warmer climates in the United States. It can be found in a variety of woodland, forest and grassland locales, but one of its primary uses is a bedding plant in highway medians or commercial landscapes. Madagascar Periwinkle also makes a striking clumping plant for home gardens as ground cover, in beddings or edgings or in containers. Unlike many other plants, Madagascar Periwinkle is best suited for poor, well-drained soil and may even fail to thrive in soils that are too fertile. These plants need regular moisture but don’t do well with overhead watering. Madagascar Periwinkle is easily propagated with semi-ripe cuttings planted in light compost with bottom heat and high humidity, or by seeds kept in the dark at 71 to 77 degrees Fahrenheit (22 to 25 degrees Celsius) until germination. The leaves may curl during the heat of the day but recover with evening dew. The flowers drop off after blooming and don’t require deadheading. Origin It is endemic to Madagascar, where it is most common in northern regions.
