Once introduced as a forage crop, hairy indigo, a legume, has become a nuisance weed in places where it's been introduced, especially in the peanut industry. It gets its common name from its hairy stems that become woody as the plant matures.

Since it has been cultivated for centuries, the native habitat of true indigo is not known. This shrub can be annual, biennial, or perennial depending on the climate where it's grown. True indigo has a long history of commercial use as a cash crop - it was a source of dark blue (indigo) dye before alternative synthetics were developed.

The roots are hard and strong. The trunk is 60 to 90 cm in height and is about 1.5 cm in diameter. The branches are elongated and green, and many branches. The leaves are alternate, odd-winged double leaves with a short petiole. Leaflets are oval or fallen oval per 4-5 pairs. The tip is round and has fine protrusions, and the base is also round and has a very short handle. It is 1 to 1.5 cm in length, 5 to 12 mm in width, and has full edge. There are many soft fur on both sides of the leaves. From summer to autumn, a flower pattern is taken out from the leaf bud, and a 3 cm long general inflorescence is added to open a beautiful purple-red butterfly-shaped flower. The flower is 5 mm long and the floret is shorter than the bud. The wings are cylindrical, split into 5 and hairy. After flowering, it produces columnar beans with a length of 3 cm, containing 3-8 seeds.

Australian indigo (Indigofera australis) is an attractive garden shrub, whose flowers provide abundant nectar for butterflies. It needs to be pruned from a young age to make it bushier and improve its shape. “Indigofera” means “containing indigo,” which some species do, but natural dyes from the leaves and stems of this plant give a pale golden color.

The coral-red flowers of coastal indigo attract birds, butterflies, and bees. The flowers occur in the early spring and last until late autumn. Its prostrate growth habit, trailing stems, and drought-tolerant nature make it an interesting choice for a xeriscape garden.

Anil de pasto (Indigofera suffruticosa) is an erect branching shrub that is native to tropical South America and North America. This species grows in dry, highly disturbed areas, including roadsides and empty fields.

Narrow leafed indigo is characterized by its slender, linear leaves and vibrant clusters of tiny, purple-indigo flowers. This herbaceous perennial prefers sunny, well-drained soils, thriving in open fields and along roadsides. Its robust root system renders it drought-tolerant, anchoring it firmly in challenging environments. The plant's striking coloration is not just ornamentation but indicative of its utility in traditional dye-making practices.

Kirilow's indigo is a perennial herbaceous plant known for its pinnate leaves and clusters of small, vibrant purple or pink flowers. Typically found in well-drained soils in meadows or forest clearings, its resilience allows it to thrive in full sun to partial shade. The production of indigo dye from its foliage illustrates kirilow's indigo's utilitarian relationship with humans.

Dracaena are popular house plants that are easy to grow. They can tolerate low-light conditions and require little watering. Their leaves range from variegated to dark green. Their characteristic traits include woody stems that grow slowly but offer a striking appearance for small spaces such as apartments or offices.

Fig trees have been cultivated in many regions for their fruits, particularly the common fig, F. carica. Most of the species have edible fruits, although the common fig is the only one of commercial value. Fig trees are also important food sources for wildlife in the tropics, including monkeys, bats, and insects.

Brambles are members of the rose family, and there are hundreds of different types to be found throughout the European countryside. They have been culturally significant for centuries; Christian folklore stories hold that when the devil was thrown from heaven, he landed on a bramble bush. Their vigorous growth habit can tangle into native plants and take over.

The popular tree family known as maples change the color of their leaves in the fall. Many cultural traditions encourage people to watch the colors change, such as momijigari in Japan. Maples popular options for bonsai art. Alternately, their sap is used to create maple syrup.

Prunus is a genus of flowering fruit trees that includes almonds, cherries, plums, peaches, nectarines, and apricots. These are often known as "stone fruits" because their pits are large seeds or "stones." When prunus trees are damaged, they exhibit "gummosis," a condition in which the tree's gum (similar to sap) is secreted to the bark to help heal external wounds.

Nightshades is a large and diverse genus of plants, with more than 1500 different types worldwide. This genus incorporates both important staple food crops like tomato, potato, and eggplant, but also dangerous poisonous plants from the nightshade family. The name was coined by Pliny the Elder almost two thousand years ago.

Most species of roses are shrubs or climbing plants that have showy flowers and sharp thorns. They are commonly cultivated for cut flowers or as ornamental plants in gardens due to their attractive appearance, pleasant fragrance, and cultural significance in many countries. The rose hips (fruits) can also be used in jams and teas.

Oaks are among the world's longest-lived trees, sometimes growing for over 1,000 years! The oldest known oak tree is in the southern United States and is over 1,500 years old. Oaks produce an exceedingly popular type of wood which is used to make different products, from furniture and flooring to wine barrels and even cosmetic creams.
