Sanchezia nobilis is named after Josef Sanchez, an early professor of botany at Cadiz in Spain. Sanchezia nobilis flowers from time to time but the beauty of the plant is in the foliage. It doesn’t like full sun, and requires some water. When growing well, it is most attractive, it becomes leggy and needs to be pruned to keep a good shape. Mealybug causing Black Sooty mold can be a problem. Updated 10/9/2018
Sansevieria is native to Africa, Madagascar and Southern Asia, it was named in honour of the Italian Pietro Antonio Sanseverino and the spelling was changed from Sanseverinia to Sanseveria in 1770. There is a large variation of plants within the group; ranging from tough desert to the slightly tender tropical species.
Sansevieria is a very accommodating plant tolerating low light, poor sandy soil and irregular watering. It is drought tolerant and will die quickly if given too much water. In the garden, it grows happily where few other plants will survive, filling odd spaces, and adding height and colour to otherwise dull areas. NASA states that by absorbing toxins it is one of the best plants for improving indoor air quality. Updated 10/9/2018

Sesbania grandiflora is named after the father of Tamil literature, Vedic sage Agastyt who, lived between the 6th and 7th centuries BC. Its origins are not certain but it has a long history in India. The seeds germinate easily and the tree grows quickly. As a young tree it is attractive, with the red parrot-shaped flowers (they also come in white). As the tree ages, it becomes less attractive because the long seed pods which dangle down, look like socks on a washing line. It is best to keep replacing with new young trees. Sesbania grandiflora is tolerant of both drought and salinity.
Siphonochilus aethiopicus is derived from the Greek siphono meaning ‘tube’, and chilus meaning ‘lip’, referring to the shape of the flower, while the specific name aethiopicus means from southern Africa.

Spathiphyllum wallisii originates from the bogs of Central America. They are very tolerant and nearly impossible to kill but if they are not cared for, it will show almost immediately. The leaves may curl and the tips will look burnt. Spathiphyllum don’t require huge amounts of water, although it is almost impossible to over-water them. They are happiest in bright light, direct sunlight can harm them. They are hungry plants and best grown in pots, planted in rich compost. They will need to be top dressed at least regularly. Eventually the plant will outgrow the pot, and will need to be re-potted; at which point it may be divided into several new plants. Updated 10/9/2018

Spathiphyllum wallisii domino is like Spathiphyllum wallisii, but with variegated leaves that are attractive. It is rather shy about flowering.
Spathodea campanulata (Nandi Flame or Tulip Tree) is native to the tropical dry forests of Equatorial Africa and, rather sadly, has been nominated as one of the 100 “World’s Worst” invaders! It was first discovered in 1787 on the gold Coast of Africa.
This is a fast growing tree and one of the most beautiful to behold at the coast. It does not grow close to the sea although they can put up with some salt. We have two growing in the garden but both are struggling due to the coral, which prevents the tree from extending its roots. Given good deep soil, the tree grows into a huge specimen and flowers abundantly. Updated 10/9/2018

Propagation is by seed or cuttings. Updated 11/9/2018
