Echeveria lauii is native to Oaxaca in Mexico (Note: all Echeverias are native to Mexico and Central America). It is slow growing and can be a challenge to get to do well. It needs full sun; the leaves tend to shrivel if the light levels are too low.
Unlike other Echeverias, these leaves are difficult to get to root, so seed is possibly the best method of propagation.
Echinopsis chamaecereus is thought to be native to Argentina, it was collected by Carlo Spegazzini in the early 20th century, since the plant has not been found growing in the wild scientists can’t be certain. These grow best in pots, the medium should be very well draining. Like all cacti, Echinopsis like strong light, with a little protection from the mid-day sun. When watering the plant, water it thoroughly and then wait until the soil is dry before giving it more water, as the plant suffers from root rot. Updated 17/9/2018
Edithcolea grandis is found throughout East Africa and the Horn of Africa. It was named after Miss Edith Cole (1859-1940), who travelled with Mr and Mrs Lort Philips on a botanical expedition in 1895. The plant grows easily in the ground, it doesn’t require any special treatment or extra water. When it is not in flower, the plant is insignificant, but the flowers are amazing and have been described as resembling a Persian carpet. Unfortunately, they smell awful—a means to attract flies (myiophilous pollination). Updated 17/9/2018

Epipremnum, native to the Solomon Islands in the Pacific, is a hemiepiphyte. The initial small leaved plant, when given a chance, will climb trees, walls, or anything it can adhere to, at which point the heart shape leaves become huge, reaching up to 3 feet across. In Northern Australia; Sri Lanka and other countries it is causing serious ecological problems.
Epipremnums are among the easiest plants to care for. To keep the leaves small the plant needs to be pot bound. The leaves are not saline tolerant and get burnt easily.
The Florida Exotic Pest Control Council list of 1999 classes it as an invasive species. All parts of this plant are toxic to humans, cats and dogs. Updated 17/9/2018
Episcia is a genus of 10 species found in the tropical regions of Central and South America. They are related to African Violets and are grown for their attractive foliage and the vividly coloured flowers.
Episcia can be difficult plants to grow. They can only tolerate small amount of sun and need to be kept on the dry side, they may look unhappy if under watered, but will die if over watered. They are easy to propagate—the plant sends out stolons (like strawberry runners), which can be cut and planted in a new pot. Updated 17/9/2018

Eucalyptus is derived from the Greek eu “well” and kalýpto “to cover” referring to the operculum on the calyx that initially conceals the flower. There are more than 700 species of eucalyptus and most are native to Australia, which is covered by 92,000,000 hectares (227,336,951 acres) of eucalyptus forest, comprising three quarters of the total area covered by native forest. In February 2016, researchers found evidence supporting the antimicrobial action of eucalyptus.

Eucharis amazonica, is native to Central and South America with 16 species. These plants grow in the rain forests and are understory plants that manage without much bright light. It is a bulbous plant, with large, broad, dark green and spectacularly showy leaves resembling Hostas. These are best grown in pots, they like to be pot bound and dislike being disturbed, only re-potted only when necessary. The tip of the bulb’s neck should remain slightly above the soil surface. Eucharis amazonica like to be kept moist all the time, but not over watered, fertilise every month to encourage the plant to flower. Amaryllis caterpillar can be a problem. Updated 17/9/2018

The Euphorbia genus name is derived from Euphorbus, the Greek physician to Juba II, King of Mauretania, was first described by Carl Linnaeus, in 1753.
Their origin is from the deserts of Southern Africa and Madagascar, and are now found all round the world. It is a very large and diverse genus, with approximately 2000 members. The plants all extrude a milky, white latex-like sap, which is poisonous. Euphorbia’s floral structure is unique; the flower’s head looks like a single flower, in fact there are many tiny florets, each reduced to the barest essential part needed for sexual reproduction. It is the only genus of plants that has all three kinds of photosynthesis, CAM, C3 and C4. Updated 17/9/2018
Euphorbia cotinifolia is native to Mexico; it is a tree, reaching 9 m, but is best treated as a shrub. Grow this plant in full sun, with well drained soil.
