Rainbow Cactus (Echinocereus Pectinatus)
Native to Mexico, Its scientific name comes from the Greek words ‘echinos’, meaning spiny, and ‘cereus’ meaning waxy. It grows in clumps with tall, narrow stems that can reach up to 6ft tall and are adorned with spines of various shades of pink, white and yellow. The flowers of Rainbow Cactus have a dark pink or red center surrounded by petals in shades of yellow, orange and green.
This species is one of the most popular decorative cacti due to its beautiful variety of colors and bold texture. They prefer semi-shaded areas as too much direct sunlight can burn their stems and dehydrate them. When grown outdoors they should be watered regularly during the warmest months so they don’t dry out. Indoors, they need bright indirect light and need to be watered sparingly only when the top soil layer is dry.
Rainbow Cactus is an easy houseplant to look after but can be challenging for beginner gardeners as it requires careful maintenance such as pruning its stems so that it doesn’t become spindly or overgrown. It also needs repotting every two years if kept indoors as its roots become congested quickly due to its high growth rate.

Rosinweed sunflower (Helianthus silphioides)
An annual member of the daisy family native to the central and eastern United States. It grows to a height of 3-5 feet, displaying large yellow flower heads which bloom in summer. The plant has several common names such as compass plant, rough sunflower, and poor man’s weather vane due to its ability to tilt its leaves towards the direction of the wind.
The leaves of Rosinweed sunflower are lanceolate in shape, covered with hairs on both surfaces, and have a characteristic white or yellow resin along their edges. These plants typically produce one or two flower heads per stem but can produce up to five when grown in ideal conditions. The flowers are bright yellow with a circumference of 1-3 inches across. Each flower head contains many small florets that give off an intense aroma while they are blooming.
This species is quite adaptable and can tolerate harsh conditions such as drought and poor soils; however, providing regular watering during dry spells will help ensure optimal growth and flowering. Additionally, it prefers full sun exposure but will also thrive in partial shade if necessary. Deadheading spent flowers will help promote reblooming throughout summertime if desired.
Roundleaf Liverleaf (Anemone americana)
Also known as American Windflower, is a low-growing herbaceous perennial native to North America. It is a member of the buttercup family and produces delicate white or pink flowers with yellow centers from early spring to late fall. The plant prefers moist, well-drained soils but can tolerate drier conditions and partial to full sun exposure.
The foliage of Roundleaf Liverleaf consists of deeply divided, 3-lobed leaves which are light green in color and covered with soft hairs. When the plant blooms, masses of small cup-shaped flowers appear atop slender stalks. These 4-petaled flowers have ruffled edges with yellow centers composed of numerous stamens and pistils. Each flower head typically measures about 1 inch across and is highly attractive to pollinators such as bees, butterflies, and hummingbirds.
As the flowers fade away, they are replaced by puffy seed heads which persist into wintertime providing additional interest in the garden until new growth reappears again in the springtime. The plant spreads by self-seeding or through propagation via root division; this allows it to form large colonies that provide a lush ground cover effect in beds and borders.
Roundleaf liverleaf has several medicinal properties associated with it including anti-inflammatory effects which may help treat various skin ailments or reduce inflammation within the body. The leaves can be boiled down into a paste for topical application on the skin while the root can be used as an ointment or herbal tea when dried first. Additionally, its fragrant flowers make a beautiful addition to cut arrangements indoors where they will last significantly longer than when kept outdoors.
Rue (Ruta graveolens)
An evergreen, bushy shrub native to Europe and Western Asia. It is a member of the Rutaceae family and grows to a height of 1-3 feet, displaying deeply cut green leaves with an aromatic scent and yellowish-green flowers. This plant has been used medicinally for centuries and is traditionally thought to help reduce inflammation, protect against infection, and improve digestive issues.
Rue can be grown in a variety of soils but prefers sandy or loamy soil with good drainage. It should be placed in full sun although it can tolerate partial shade as well. When growing outdoors, it will need regular water during summertime; however, over-watering can lead to root rot so allow the soil to dry out between waterings. Over time, this small shrub will spread by self-seeding producing multiple large clumps that add texture and color contrast to the garden throughout summertime until fall when the foliage turns yellow and dies back.
Although rue has many medicinal benefits, it can also be toxic if taken in excessive amounts as it contains volatile oils which may cause nausea or vomiting if ingested too much. As such, it should not be taken internally without proper medical supervision. However, topically it is generally safe and can be used as a poultice or decoction on the skin to ease pain or reduce inflammation associated with joint problems like arthritis or gout. Additionally, its distinct aroma makes it an excellent natural insect repellent against common pests such as fleas and ants when added to bathwater or sprays.
Historically Rue was often used in religious ceremonies due to its strengthening properties; it was thought that inhaling its scent would strengthen one’s faith while touching it brought protection from evil spirits! In more modern times, this herb is still popularly used for culinary purposes as well; its pungent taste adds a unique flavor to salads or cooked dishes like stews and soups making them even more delicious!
Rusty foxglove (Digitalis ferruginea)
A herbaceous perennial native to the Mediterranean region, with a preference for limestone soil and sunny locations. It typically grows in a mound shape to a height of 2-3 feet, with silvery-green ovate leaves and clusters of distinctive yellow tubular flowers. The flowers are speckled with rusty orange spots along the throats and bloom from late spring into summer. This species has been widely cultivated throughout Europe since the 19th century due to its attractive bell-shaped blooms and naturalizing ability; it makes an excellent choice for cottage gardens or mixed borders as it adds bright color and texture to any garden setting.
When planting, Rusty foxglove should be given plenty of room as it can spread quickly by self-seeding; this allows it to form large colonies that can reach up to 5 feet wide! Suitable companions include other perennials such as daylilies and daisies which will help fill out any gaps in between the foliage. In terms of maintenance, deadheading spent flowers can help encourage additional blooming while cutting back the stalks in late fall may help reduce any potential winter dieback. Additionally, this plant is drought tolerant once established so watering should only be necessary during periods of extreme heat or drought stress.
Medicinally, Rusty foxglove contains several compounds known as digitalis glycosides which are used in heart medications due to their ability to slow down a racing heartbeat or correct irregular heart rhythms. These same compounds are also believed to have anticancer properties although further research is still needed before these claims can be confirmed definitively. Regardless, this species is an interesting addition to any landscape, providing visual interest throughout all seasons while helping add life-saving medicinal qualities when consumed responsibly!
