Scientific Name Sedum nussbaumerianum Bitter
Common Names Coppertone Stonecrop, Nussbaumer’s Sedum Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Sedum
Flower Color: Pure white Bloom Time: Late winter to spring Description Sedum nussbaumerianum is a low growing, evergreen, perennial subshrub, up to 8 inches 20 cm) tall, with reddish-brown stems that hold elongating up to 3 inch (7.5 cm) wide rosettes of yellow-green to coppery-red, rounded, up to 1.6 inches (4 cm) long leaves pointed at tips. The flowers are small, pure white, star-shaped and fragrant. Hardiness USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
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 Sedum 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. Origin Native to Mexico.

Scientific Name Sedum morganianum E. Walther
Common Names Burro’s Tail, Donkey’s Tail, Lamb’s Tail, Horse’s Tail, Sedum Burrito Scientific Classification Family: Crassulaceae Subfamily: Sedoideae Tribe: Sedeae Subtribe: Sedinae Genus: Sedum
Flower Color: Pink Bloom Time: Summer Description Sedum morganianum is an evergreen trailing succulent with many over 2 feet (60 cm) long or more, pendent stems arising from base. The leaves are fleshy blue-green, up to 0.5 inch ( 13 mm) long, crowded along stems. Flowers readily emerge in late summer in hanging clusters of small blossoms in pink to red.
How to Grow and Care Donkey’s Tails are pretty forgiving plants—if you forget to water them once or twice, they’ll probably be just fine. If you want your plant to really thrive, make sure to provide strong light, fertilizer during the growing season, and adequate moisture during the growing season. Too often, these are left to fend for themselves, simply because they can. But with a little effort, the plant can be a remarkable specimen. Repot as needed, preferably during the warm season. To repot a Donkey’s Tail, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot. Propagation is by seed or by cuttings. Individual leaves can be sprouted by placing them into a succulent or cactus potting soil, then covering the dish until they sprout. Large Donkey’s Tail plants can also be divided during repotting. Origin Native to Southern Mexico and Honduras.

Scientific Name Scilla siberica Haw.
Common Names Siberian Squill, Wood Squill Synonyms Scilla siberica subsp. siberica, Othocallis siberica, Scilla cernua Scientific Classification Family: Asparagaceae Subfamily: Scilloideae Tribe: Hyacintheae Subtribe: Hyacinthinae Genus: Scilla
Flower Color: Deep violet-blue Bloom Time: Early to late spring Description Scilla siberica is a bulbous perennial up to 8 inches (20 cm) tall and up to 2 inches (5 cm) wide, with 2 to 4 strap-shaped leaves appearing in early spring, at the same time as the nodding, blue, bell-shaped flowers. The flowers have 6 petals and 6 stamens, and are arranged singly or in racemes of 2 or 3. Petals may be reflexed to the horizontal when sunlight is bright, but are more often cup-shaped. After flowering, the flower stems become limp as capsules (pods) mature. At maturity, the capsules become purple and split open, releasing small, dark brown seeds. Hardiness USDA hardiness zone 2a to 8b: from −50 °F (−45.6 °C) to 20 °F (−6.7 °C).
How to Grow and Care Scilla is adapted to full sun or dappled shade and likes well-drained soil. It naturally grows in rocky wooded areas, so it is just at home in dryish semi-wild parts of the landscape as it is in a rich, moist garden bed. Bulbs should be planted in fall. Plant the bulbs in loose soil three to four inches deep and 8 inches (20 cm) apart with the tapered end pointed up. Scilla should receive regular water during the spring flush of growth. However, since the weather tends to be cool and moist during this time, it is generally not necessary to irrigate. In fact, it is important to not over water, as the bulbs can rot. The foliage should be left after the flowers fade, though it, too, fades in the heat of summer. Once Scilla leaves are all yellow they may be cut to the ground, and the plant allowed to remain dormant until the following spring. It is important that the bulbs not be watered during the dormant period. Origin Native to southwestern Russia, the Caucasus, and Turkey. Despite its name, it is not native to Siberia.

Scientific Name Saintpaulia ionantha subsp. grotei (Engler) I. Darbysh.
Common Names African Violet Synonyms Saintpaulia grotei (basionym), Saintpaulia confusa, Saintpaulia amaniensis, Saintpaulia difficilis, Saintpaulia magungensis Scientific Classification Family: Gesneriaceae Genus: Saintpaulia
Flower Color: Purple Bloom Time: Flowers freely Description Saintpaulia ionantha subsp. grotei is a tender, herbaceous, flowering, indoor perennial, up to 6 inches (15 cm) tall and up to 12 inches (30 cm) wide. May be multiple-stemmed, but usually grows as a single-crowned plant. It has purple flowers and medium, green, slightly serrated and quilted leaves. Saintpaulia ionantha subsp. grotei - African Violet. Hardiness USDA hardiness zone 11a to 12b: from 40 °F (+4.4 °C) to 60 °F (15.6 °C).
How to Grow and Care African Violets will thrive in bright, warm and humid conditions. Keep water from touching their leaves or it will leave brown spots. Remove dead flowers and leaves as soon as you seen them to encourage a healthier plant. Regularly check the soil and plant to make sure there is no accumulation of dead leaves. This will encourage rot. Growing these houseplants is really a matter of balance; you have to make sure that the different factors that go into their cultivation all are weighted against each other. They should be kept in moist enough conditions that they don’t dry out, yet still exposed to a fresh breeze to avoid letting them get too stuffy, and exposed to sunlight without damaging their leaf tips. Don’t be discouraged if your African Violets suffer some damage — it’s all part of the process. African Violets do better when they are slightly underpotted. Repot only when necessary into a pot that is one size up. To repot these plants, simply grab the plant as a whole, lift it, and replace it into a larger container, making sure not to damage their root systems in the process. Origin Native to Kenya and Tanzania.

Scientific Name Sandersonia aurantiaca Hook.
Common Names Chinese Lantern Lily, Christmas Bells, Golden Lily of the Valley Scientific Classification Family: Colchicaceae Genus: Sandersonia
Flower Color: Orange Bloom Time: Late spring and summer Description Sandersonia aurantiaca – Christmas Bells is a slender-stemmed perennial plant and a climber that can reach up to 30 inches (76 cm) in height, with lance-shaped, medium green leaves. The flowers are bell-shaped and bright orange in color. Blooms in late spring and summer.
How to Grow and Care Sandersonia loves a sunny spot with well drained loamy soil enriched with complete fertilizer. They only require water during the growing period until the flowers have finished, we then find it to be more drought tolerant than we expected. However they do not like to be too wet over winter. The tuber has two fleshy prongs emerging from the central ‘bulb’. These prongs should be planted down and covered with 2 inches (5 cm) of top soil with about 3.1 inches (8 cm) between each tuber. When shoots emerge they need to be protected from snails and slugs as they find them most desirable. They will do well in a pot or container so long as there is good drainage. They increase by making a new tuber each from the growing prong and often a small ‘nut’ on the other prong. They can also be grown from seed which is usually ready to harvest about the end of April. Seed should be planted early winter, sown thinly in trays or pots using a very well drained potting medium and covered with 0.4 inch (1 cm) of mixture. Origin Native to South Africa.

Scientific Name Kohleria warszewiczii (Regel) Hanst.
Synonyms Kohleria digitaliflora, Gesneria regeliana, Isoloma digitaliflorum, Isoloma regelianum, Isoloma warszewiczii, Kohleria violacea, Sciadocalyx digitaliflora, Sciadocalyx warszewiczii Scientific Classification Family: Gesneriaceae Subfamily: Cactoideae Tribe: Cacteae Genus: Kohleria
Flower Color: Purple Bloom Time: Summer to autumn Description Kohleria warszewiczii is a perennial plant up to 2 feet (60 cm) tall, with an upright to spreading habit. The flowers are nodding, rich purple, with furry trumpets. Flowering period extends from summer through the autumn.
How to Grow and Care Put your Kohleria where it’ll get plenty of light, but out of direct sun. Filtered light from a south- or west-facing window will give it the light it needs. Keep the soil evenly moist during the growing season, but take care not to overwater. Dry soil will cause the plant to go dormant. Soggy soil will quickly cause the rhizomes to rot. You can expect dozens of blooms on plants in spring and summer. You’ll get the most blooms by providing plenty of bright, indirect light. This one likes to be slightly pot-bound, and blooms best this way. Repot in spring when it has outgrown its pot. Always use a container with drainage holes to prevent soggy soil. Divide rhizomes in spring and pot separately. Or take 4-inch (10 cm) leaf tip cuttings with at least 1 pair of leaves attached and root in moist potting mix. Cover the whole thing with plastic or a glass cloche to hold in moisture. Cuttings root easily in about 4 to 6 weeks. Origin Native to Colombia.
