Acanthus montanus, commonly known as Mountain Thistle, Bear's Breeches, or Alligator Plant, is a robust evergreen perennial in the Acanthaceae family native to tropical West and Central Africa. It forms a dense clump of large, glossy, deeply lobed dark green leaves that may reach 2 to 3 feet (60 to 90 cm) in length, while flowering stems can grow 4 to 6 feet (1.2 to 1.8 m) tall. The bold foliage creates a dramatic tropical effect, making this species an excellent choice for shaded borders and woodland-style gardens.

Tall spikes of hooded white to pale pink flowers with purple bracts appear above the foliage over an extended season, attracting bees, butterflies, and other pollinating insects. Acanthus montanus grows best in partial shade or filtered sun and fertile, well-drained soil with regular moisture, although established plants tolerate short dry periods. It is well suited to tropical and subtropical gardens and also performs well in large containers. Hardy in USDA Zones 9b-11, this striking species is valued for its architectural foliage, impressive floral display, and reliable performance in warm climates.

Common Yarrow is a drought tolerant species of which there are several different ornamental cultivars.

The herb is purported to be a diaphoretic, astringent, tonic, stimulant and mild aromatic. Yarrows are well suited to the wildflower garden. The soft, lacy foliage makes an interesting and beautiful groundcover. The flowerheads are used in arrangements, fresh and dried.

Achimenes species and hybrids are commonly grown as greenhouse plants, or outdoors as bedding plants in subtropical regions. The species have been extensively hybridized, with many of the hybrids involving the large-flowered species A. grandiflora and A. longiflora. Many of the species and their hybrids have large, brightly colored flowers and are cultivated as ornamental greenhouse and bedding plants.

Acnistus arborescens is a large shrub native to Central and South America known as Hollowheart. In its natural habitats, it grows in full sun and reaches heights of as high as 10 feet, or as a small tree up to 20 feet in height. It is also known for its abundance of white, off-white, blue, lavender, and purple flowers, as well as for its ability to attract butterflies and hummingbirds.

This plant is best grown in USDA zone 9-11 in well-draining soil and with regular waterings. In warm climates, it can have year-round growth, while cold climates may require bringing the plant indoors in winter or providing frost protection such as an insulating wrap. If planted in a pot, it is recommended to place it in a sheltered location and use a balanced fertilizer on a regular basis. If a cold snap is predicted, the pot should be moved indoors to a sunny location.

Traditionally, Acnistus arborescens has also been used ethnomedically to treat cancer. However, no scientific evidence is available to attest to its efficacy as an herbal remedy.

In conclusion, Acnistus arborescens is an attractive, fast-growing shrub or small tree that is easy to care for and provides a splash of color to attract hummingbirds and butterflies. While it can have ethnomedical advantages, more research is needed to verify the claims of its healing properties.

This shrub is one of three members of the genus, Acokanthera. It belongs to the same family as many popular subtropical ornamental plants such as frangipani, allamanda and oleander, as well as the impala lily and num-num. This family is characterized by having sweetly scented flowers and sticky, milky sap which is very poisonous. The Bushman's poison is a hardy drought. It's a frost resistant, evergreen shrub that tolerates full sun but prefers shade, it also does well as a container plant.

Acokanthera oppositifolia (Bushman's Poison) is a large shrub, typically growing 5-10 feet tall. It has glossy dark green leaves that are opposite and grow up to 3-4 inches long. In the spring and summer months, the Bushman's Poison flowering shrub is adorned with white, off-white flowers which have a strong, sweet, perfume-like scent.

In its native habitat, the Acokanthera oppositifolia is mainly used for its ethnomedical applications, such as treatment for headaches, inflammations, fever and even malaria. However, it should be noted that the milky sap is considered to be poisonous or toxic and should not be ingested.

As an ornamental plant, the Bushman's Poison works well in well-drained soil in full sun or partial shade and requires moderate amounts of water. It is suitable for growing in regions with USDA Hardiness Zones 9-11 and a mature plant can tolerate short periods of time in temperatures as low as 30°F. When growing in a pot, it is advisable to move the container to a protected area during cold winters and to protect the roots from the frost.

Different Aconitum species (and their varieties) scattered across temperate regions of globe.

These are handsome plants, the tall, erect stem being crowned by racemes of large and eye-catching blue, purple, white, yellow or pink zygomorphic flowers. Aconitum is grown in gardens for its attractive spike like inflorescences and showy flowers.

All Aconitum plants contain poisonous alkaloids that can, in sufficient quantity, be deadly. Man has used Aconitum as a medicine and poison for thousands of years. Outside Europe it was widely used for its medical properties.

The fast-growing, climbing vine is very hardy, and is capable of surviving slow temperature drops to -34 C (-30 F), although young shoots can be vulnerable to frost in the spring. This vine needs a strong (vines are heavy) support structure on which to grow such as a trellis, arbor, patio overhead, fence or wall.

Actinidia sp. (Actinidia) is an attractive and fast-growing perennial plant native to eastern Asia. It typically will reach a mature size of 5-10 feet tall, either as a large shrub or as a vine or creeper. This plant is well-suited for full sun and semi-shade areas, and requires regular water for good growth. Actinidia sp. produces white and off-white flowers, which are especially attractive in spring and summer.

Ethnomedical uses of Actinidia include edible Kiwi fruits; the fruits are high in vitamin C and other healthy elements. Depending on the species, a mature plant can produce a range of up to a few hundred fruits per season. The fruits can be tart or sweet, and are usually eaten fresh or canned as juices or jams.

Actinidia is a hardy plant, able to withstand cold temperatures at least to 30s F for a short time. It is optimally grown in USDA Zone 8-10 and is an excellent choice for gardeners in cold climates who would like to try growing the plant in a pot. To do this successfully, it is important to make sure the container is of an appropriate size and is stored in an area free from harsh winter winds. Potting soil should be kept moist and watered as needed, and if temperatures are expected to drop far below freezing, the pot should be covered.

Overall, Actinidia is a beautiful and versatile plant that is easy to care for and produce a bounty of edible fruits which are high in vitamins and other essential nutrients. While it is hardy to moderately cold temperatures, careful precautions should be taken if grown in a pot to ensure the Actinidia is able to survive the winter and produce healthful fruit for many seasons to come.
