Lesson Three:

Lesson Objectives:

• For students to grasp the uses of some basic plants, common to the practice of Herbology
• By the end of this lesson students should feel comfortable discussing these plants in a recreational setting
• To take a look at four categories of plants and at their natural habitats, any special requirements under planting and care, as well as the properties of the plant.

Gillyweed: This plant is native to the Mediterranean sea, and it grows to a height of four-seven centimetres. To grow it requires soil with a pH range of around 7.9–8.4, which sets it at moderately alkaline. This plant consumes large amounts of water but needs little sunlight. This plant grows in bushels and is grey-green in colour. Consumption by human being: If a human being consumes Gillyweed, it results in temporary growth of gills and webs between toes and fingers. The effect lasts for about an hour in fresh water, and up to three hours in salt water.  Properties: This include a refreshed, nourishing feeling when it is ingested. 

Bonus recipe: Gillywater: You will need water, cucumber, and several sheaves of Gillyweed. 

 Valerian Root and Sprigs: This plant, also known under its scientific name Valeriana officinalis, is native to Europe and some parts of Asia, although it is also know found in North America. Valerian may grow to be five feet, and forms bunches of attractive white flowers. At least seven hours of sun is required to keep healthy. it requires soil of a pH range of 4.5–5.0, very strong acid, and should be harvested in the fall or early spring. Properties: This plant has several sedative qualities and is used in many sleeping potions. The root is also anxiolytic, used in many calming draughts. Perfumes made of the sprig smell like a mix cherry and vanilla.Uses: This plant is used in potions and draughts such as the Draught of the Living Dead and the Forgetfulness Potion. 

Knotgrass: Knotgrass is the symbol of tying two people together. Knotgrass grows wherever there is a neutral level of pH level in soil (Slight acid) 6.1–6.5 to (Neutral) 6.6–7.3, and plenty of water. The more sunlight, the faster it will grow. It's height can be anywhere between two inches to fourteen feet. Knotgrass flowers in the summer and needs lots and lots of water, and is native to Europe. Uses: Knotgrass is used in the Polyjuice Potion, and some love potions. Knotgrass is used by healers to treat urinary tract infections as well as fertility issues. Caring for the plant: When the flowers are done blooming, the stem must be cut below the flowering. 

Dittany: The origanum dictamnus is only found in Crete, Greece, and grows in soil with an average pH level of (Neutral) 6.6–7.3.  Dittany grows twenty centimetres to thirty centimetres in height, and requires warmth and sunlight to thrive.Uses: Dittany is known for its romantic qualities, but also aids in curing ailments of all type, and can be used to prevent scarring. It is only considered essential to healers, potioneers, romancers and parents alike. To use Dittany, it must be liquidized. If this plant is liquidized, it will be brown in colour. Caring for the plant: If Dittany is grown and kept in a greenhouse,one must keep the temperature in the greenhouse at an even temperature of 13 degrees Celsius. Seeds should be lightly covered by soil, and then sprinkle lightly with water. Wait until the soil feels dry to water the Dittany. Potions: Dittany also be used in the Wiggenweld Potion.
