Scientific Name Helleborus lividus Aiton ex Curtis
Common Names Majorcan Hellebore, Blue-Grey Hellebore, Purple Hellebore, Lenten Rose, Livid Lenten Rose Synonyms Helleborus trifolius subsp. lividus, Helleborus trifolius var. lividus, Helleborus triphyllus Scientific Classification Family: Ranunculaceae Subfamily: Ranunculoideae Tribe: Helleboreae Genus: Helleborus
Flower Color: Pinkish-green Bloom Time: Midwinter to early spring Description Helleborus lividus is an evergreen perennial up to 18 inches (45 cm) tall and up to 12 inches (30 cm) wide, with biennial stems and deep green or bluish green, glossy leaves. The flowers are pinkish-green, up to 2 inches (5 cm) wide, borne in open clusters from midwinter to early spring.
How to Grow and Care When planting from seed or division, place the Hellebore into well-draining, organic soil in a filtered sun or shady location. The Hellebore plant will return for many years; make sure the space will accommodate growth and has proper sunlight. Hellebores need no more than a few hours of dappled light and grow successfully in shady areas. Plant the Hellebore under deciduous trees or scattered through a woodland garden or shaded natural area. Soaking the soil in which the Hellebore is growing helps the Hellebore plant to look its best. Hellebore care includes removal of older leaves when they appear damaged. Care for Hellebores should also include careful fertilization. Too much nitrogen may result in lush foliage and a shortage of blooms. Plant Hellebore seeds in the fall. A 60-day moist chilling period is needed when planting seeds of the Hellebore plant. Planting seed in fall allows this to happen naturally in areas with cold winters. Wait three to four years for blooms on young plants grown from seed. Divide overgrown clumps in spring, after flowering or in autumn. Origin Native to Majorca and possibly nearby Cabrera, Spain.

Scientific Name Helianthus annuus L.
Common Names Sunflower, Grand Soleil (French), Tournesol (French), Sonnenblume (German), Girasole (Italian), Himawari (Japanese), Haebaragi (Korean), Girassol (Portuguese), Girasol (Spanish), Alizeti (Swahili), Solros (Swedish) Synonyms Helianthus annuus subsp. annuus, Helianthus annuus var. annuus, Helianthus annuus f. annuus, Helianthus aridus, Helianthus aridus var. aridus, Helianthus erythrocarpus, Helianthus indicus, Helianthus jaegeri, Helianthus lenticularis, Helianthus macrocarpus, Helianthus macrocarpus, Helianthus multiflorus, Helianthus ovatus, Helianthus platycephalus, Helianthus tubaeformis Scientific Classification Family: Asteraceae Subfamily: Asteroideae Tribe: Heliantheae Genus: Helianthus
Flower Color: Yellow and brown Bloom Time: August to September Description Helianthus annuus is an annual herb, up to 10 feet (3 m) tall, with an erect, unbranched, rough-soft-hairy stem. The leaves are broad, coarsely toothed, rough and mostly alternate, up to 15 inches (40 cm) long. The flower is up to 15 inches (40 cm) in diameter and is actually a flower head of numerous small individual 5-petaled flowers (florets). The outer flowers which resemble petals are called ray flowers. The flowers in the center of the head are called disk flowers. The ray flowers are tongue-like and yellow in color, and the disk flowers are small, tubular and brownish. The fruit is long, flat-oval, slightly angular, smoothly haired–virtually glabrous cypsela, usually tipped with 2 withering bristles.
How to Grow and Care If you decide to add Sunflowers to your garden, there are a few things you will want to keep in mind. First of all, they are called sunflowers for a reason. They need sun. Make sure that the location you choose for your Sunflowers gets full sun. Second, you do not need to worry about soil too much. They are not picky about the conditions of the soil, but they are plants. They will do better in better soil. Third, Sunflower seed shells do contain a substance that is toxic to grass. So, you will need to either harvest the Sunflower heads before the seeds begin to fall out or you will need to plant your Sunflowers in a location where you do not mind any nearby grass being killed. Fourth, keep in mind the height of the Sunflower variety you have chosen. A giant, twelve foot variety will end up acting very much like a small tree and may shade the surrounding flowers. Origin Native to the south-west of the United States, around the New Mexico area.

Scientific Name Haworthia attenuata (Haw.) Haw.
Common Names Zebra Plant, Zebra Haworthia Synonyms Haworthia attenuata var. attenuata, Apicra attenuata, Aloe clariperla Scientific Classification Family: Xanthorrhoeaceae Subfamily: Asphodeloideae Genus: Haworthia
Flower Color: White and green Bloom Time: Can be ever blooming if you snip off each bloom when it dies. Description Haworthia attenuata is a stemless clustering perennial succulent, up to 6 inches (15 cm) tall. The rosettes are 3 – 6 inches (7 – 15 cm) in diameter, with 30 – 40 dark green leaves, 3 inches (8 cm) long with white tubercles. The Inflorescence is 16 inches (40 cm) tall, white flower with green veins.
How to Grow and Care Display Zebra Plant anywhere it can receive plenty of sun or bright light. South facing windows will provide the most sun, however, east or west provide direct sun part of the day that I find more suitable. During the growing season from April to September water the Zebra Plant thoroughly and then water when the soil becomes dry to the touch (not bone dry though). Winter is a tricky time for these plants although they are a tough species. Many growers will overwater then alongside cold temperatures or drafts the plant can become very sick, or even die. The leaves are storage organs so during the winter water much less and allow the top soil to dry out. Use a cactus potting mix that drains wells and provides plenty of air to the small roots. If making you own mix or buying another type, use part potting soil, part perlite and part sand. Origin Native to South Africa (Eastern Cape).

Scientific Name Cheiridopsis denticulata (Haw.) N.E.Br. Common Names Carpet Weed, Lobster Claws
Synonyms Mesembryanthemum denticulatum (basionym), Cheiridopsis candidissima, Cheiridopsis denticulata var. denticulata, Cheiridopsis inconspicua, Cheiridopsis littlewoodii, Cheiridopsis macrophylla, Cheiridopsis vanheerdei, Mesembryanthemum candidissimum, Mesembryanthemum denticulatum var. candidissimum Scientific Classification Family: Aizoaceae Genus: Cheiridopsis
Description Cheiridopsis denticulata is a perennial, compact, cushion-forming succulent plant, up to 4 inches (10 cm) tall and up to 12 inches (30 cm) across. Leaves are grey-white, up to 2.6 inches (6,5 cm) long, up to 0.4 inch (1 cm) wide, simple or somewhat toothed on the keel from which its name derives. Flowers are cream to pale yellow, often violet to red at tips and outside and up to 3.2 inches (8 cm) in diameter.
How to Grow and Care The basics of Mesemb care are very simple, with free-draining soil, plenty of sun and ventilation, and regular light watering in the right season. Yet the difficulties are endless, trying to adapt to the Mesembs’ own adaptability and to follow their growth habits in your particular conditions. Mesembs require a loam-based compost with the addition of extra drainage material such as horticultural grit or perlite. They all like good light conditions and plenty of ventilation.
Some are relatively cold-hardy and can even survive mild winters outside. Most will survive temperatures down to freezing point. There are some Mesembs which begin to grow in the autumn as the temperature drops and the days get shorter. Because different genera within the Mesemb family have different growing conditions, care mast be taken with watering. Some genera will benefit from a light spray water to prevent shrivelling during their dormant period.

Scientific Name Sedum lineare Thunb. Common Names Needle Stonecrop, Carpet Sedum, Linear Stonecrop Herb, Stonecrop
Synonyms Sedum anhuiense, Sedum subtile Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Sedum
Description Sedum lineare is a mat-forming evergreen succulent plant with bushy and semi trailing stems, up to 6 inches (15 cm) tall. The new growth on this plant is often upright and then lies down under the weight of the stems and in shade it tends to grow slightly more open and taller. The leaves are succulent, light green or pale greenish yellow, up to 1 inch (2.5 cm) long. It is in flower from Jul to August. The flowers are star-shaped, yellow and up to 0.8 inch (2 cm) wide.
How to Grow and Care When growing Sedum, keep in mind that Sedum plants need very little attention or care. They will thrive in conditions that many other plants thrive in, but will do just as well in less hospitable areas. They are ideal for that part of your yard that gets too much sun or too little water to grow anything else. A common name for Sedum is Stonecrop, due to the fact that many gardeners joke that only stones need less care and live longer.
Sedum is easily planted. For shorter varieties, simply laying the plant on the ground where you want it to grow is normally enough to get the Sedum plant started there. They will send out roots from wherever the stem is touching the ground and root itself. If you would like to further ensure that the plant will start there, you can add a very thin covering of soil over the plant. For taller Sedum varieties, you can break off one of the stems and push it into the ground where you would like to grow it.

Scientific Name Titanopsis calcarea (Marloth) Schwantes Common Names Concrete Leaf, Jewel Weed, Carpet Leaf, Sheep’s Tongue, Living Stone
Synonyms Titanopsis calcareum Scientific Classification Family: Aizoaceae Subfamily: Ruschioideae Genus: Titanopsis
Description Titanopsis calcarea (Concrete Leaf) is a mat forming succulent with basal rosettes up to 3 inches (7.5 cm) in diameter. Fleshy leaves, up to 1 inch (2.5 cm) long with truncate tip, usually grey or blue-green, densely covered at the apex with whitish, creamy grey, ochre, red or bluish rough tubercles. Yellow to orange flowers, 0.8 inch (2 cm) in diameter.
Hardiness USDA hardiness zone 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C). How to Grow and Care Titanopsis grows to form clumps. These clumps can be divided for further propagation of the plant. The maintenance of Titanopsis is not difficult. They need a sandy substrate with little organic material. They are winter grower, and should be kept relatively dry in summer. They should also be kept dry when the temperature is below 45° F (7° C).
Division of larger clumps is possible in some cases, but as most species have tuberous rootstocks and offset slowly, seed production is the most common method of propagation. Sow it in spring and it should start flowering after two years.

Scientific Name Escobaria sneedii Britton & Rose Common Names Sneed’s Pincushion, Sneed’s Pincushion Cactus, Sneed’s Cory Cactus, Sneed’s Cscobaria, Carpet Foxtail Cactus
Synonyms Coryphantha sneedii, Mammillaria sneedii Scientific Classification Family: Cactaceae Subfamily: Cactoideae Tribe: Cacteae Genus: Escobaria
Description Escobaria sneedii is a small cactus growing up to 11 inches (27 cm) tall. The species may branch profusely, even when small and immature. It is coated densely in patches of bright white spines; each patch may have nearly 100. Depending on the substrate, the spines may be tinted with yellow, pink, purple, or brown. They may have dark tips and as the cactus ages the spines darken to gray and even black. The shape of the spines separates the varieties: Escobaria sneedii var. sneedii has straight spines that spread from the areole and Escobaria sneedii var. leei has curved spines. The cactus blooms in spring, bearing flowers up to 1.2 inches (3 cm) long near the top of its body. The flower is variable in color. It can be bright to pale pink, white to off-white, greenish, or brownish in color. Each tepal may have a darker midstripe of most any color. The fruit is generally either red or green, usually tinged with other colors, and may be up to 0.8 inch (2 cm) long.
How to Grow and Care The Escobaria are very susceptible to rot and therefore require a well-drained soil, without any water excess or stagnation; it has been observed that the plants also suffer the environmental humidity, which should preferably remain very low (30-50%). Avoid watering during the winter, when the plant is dormant: watering Escobaria in cold environmental conditions will almost certainly lead to death of the plant. In the growing season the plants, whose growth is typically quite slow, like to perceive a significant temperature difference between night and day.

Scientific Name Echeveria agavoides Lem. Common Names Molded Wax, Molded Wax Agave, Carpet Echeveria Synonyms Cotyledon agavoides, Echeveria obscura, Echeveria yuccoides, Urbinia agavoides, Urbinia obscura
Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Echeveria
Description Echeveria agavoides is a small, stemless, succulent plant, up to 5 inches (12.5 cm) tall, with a star-shaped rosette of fat leaves up to 8 inches (20 cm) in diameter. The apple-green leaves are triangular, with reddish edges and a terminal spine. The inflorescences in summer appear on slender, single-sided cymes up to 20 inches (50 cm) long. The flowers are pinkish-red with petals tipped with dark yellow.
How to Grow and Care Most of the common Echeveria species are not complicated succulents to grow, provided you follow a few basic rules. First, be careful never to let water sit in the rosette as it can cause rot or fungal diseases that will kill the plant. Additionally, remove dead leaves from the bottom of the plant as it grows. These dead leaves provide a haven for pests, and Echeveria are susceptible to mealy bugs. As with all succulents, careful watering habits and plenty of light will help ensure success.
Most Echeveria can be easily propagated from leaf cuttings, although a few are better from seeds or stem cuttings. To propagate a leaf cutting, place the individual leaf in a succulent or cacti mix and cover the dish until the new plant sprouts. Repot as needed, preferably during the warm season.

Scientific Name Carpobrotus edulis (L.) N. E. Br. Common Names Ice Plant, Highway Ice Plant, Freeway Ice Plant, Pigface, Hottentot Fig, Sour Fig, Sea Fig, Cape Fig
Synonyms Mesembryanthemum edule (basionym) Scientific Classification Family: Aizoaceae Subfamily: Ruschioideae Tribe: Ruschieae Genus: Carpobrotus
Description Carpobrotus edulis is a creeping, mat-forming perennial succulent with leaves crowded along the stem, up to 5 inches (12.5 cm) long and up to 0.5 inch (1.2 cm) thick, sharply 3-angled and triangular in cross-section, yellowish to grass-green and reddish when older. The flowers are yellow or light pink, up to 6 inches (15 cm) in diameter. The fruit is up to 1.4 inches (3.5 cm) in diameter, fleshy, shaped like spinning top, on a winged stalk, becoming yellow when ripe.
How to Grow and Care Growing Carpobrotus in containers is ideal, and you can overwinter them in temperate regions. Just bring the pot in and water it deeply. Cut back the plant and let it dry out and languish for the winter in a warm location. In March, resume regular watering and move the plant to a full light situation where it has some protection from burning rays. Gradually reintroduce the plant to temperatures outdoors until it can tolerate a full day outside.
The only serious threats to the plant’s health are spittle bugs and some root rots and stem rots. You can avoid the rot by minimizing overhead watering during periods in which the plant will not dry off before nightfall. The bugs will remove themselves if you spray with a horticultural soap.
