Family Bromeliaceae

Flowering Pot Plants

Bromeliads is the name given to a group of plants which mainly originate in South America. The group contains plants which are quite diverse in appearance, such as Aechmea fasciata and Bilbergia nutans. Several of the genera contain epiphytes, which in their native habitat grow on the trunks and branches of trees, obtaining their food from the air mainly through their leaves. Others are terrestial plants which grow in the ground obtaining their plant food through their roots. Probably the most...

Plants For Summer Pots

Originally, when plants were being classified by Linnaeus in the eighteenth century, azaleas were treated as a separate genus, because at that time only deciduous species were known in Europe. Later, however, when evergreen species were introduced, botanists decided that ail azaleas should be classified under the genus Rhododendron, It ts to be understood, then, that when a nurseryman or gardener talks about Azalea timsii botanically speaking he is referring to Rhododendron simsii. The fact...

Camellias are flowering shrubs of which there are numerous cultivars and hybrids. These have been raised from the many different species introduced to Europe from China and Japan. Of the many different types available Camellia japonica hybrids are the plants usually grown for pot culture. They were very popular in Victorian times and many large estate owners devoted a whole greenhouse to their cultivation. Some magnificent specimens, bearing hundreds of flowers, were grown. Actually Camellia...

BELGIAN INDIAN AZALEAS These are the best plants for forcing into flower from mid-autumn onwards. They are not usually sold as named varieties nowadays, but they are available in many shades of reds and pinks, and also as bi-colours such as pink with white edges. Ideally you need about ten to twelve plants to cover the six-month autumn to spring period. The most economical way to acquire a collection is to buy small plants, because the price increases with the diameter of the head of the plant....

Autumn Cuttings

Cuttings of regals should be taken during late summer and zonals in early autumn. They will root more quickly than spring cuttings and should be potted in 3Vj-in 9-cm pots in compost Eft as soon as ready. While in these pots the plants should be stopped, when ready, in the same way as for spring cuttings. The plants will usually be ready for stopping by late autumn. By mid-winter they should be ready for potting on into 4' i-in or 5-in 11,5- 12-cm pots. When the side shoots are 2-2xh in 5-6.3...

Potted Lantana Plant

The species are mainly of South American origin and are of interest only as the parents of the hybrid varieties which are vastly superior. The principal species used in raising the hybrids were Lantana camara which occurs with yellow, red or violet flowers, L. itivea white and L. irtfolia red . L. camara grows wild on all the islands of the Dutch Fast Indies, as well as tropical South America, where infusion from the leaves is used as a tonic and a stimulant. It has the common name Surinam tea...

Bougainvilleas are by nature climbing plants, but a number ofhybrids developed from B.bumana are less vigorous than the species and can be trained as bushy shrubs, or alternatively as compact plants on a wire hoop or a framework. The common name of this plant is 'paper flower', which is a description of the coloured bracts formed when the plant blooms. The flowers are small and insignificant, but the large bracts which give the plant its very attractive appcarance are brightly coloured and have...

Charles Plumier is recorded as finding the first fuchsias in 1703 in San Domingo in the West Indies, which he named Fuchsia tryphylla flore coccinea. The name Fuchsia was in commemoration of Leonhart Fuchs, 1501 -66 , a physician and herbalist. Father Charles Plumier, or Pere Plumier, was a distinguished French traveller and botanist, who made three voyages to the West Indies and tropical South America, and in 1703 he published a book dealing with the plants he had discovered in his travels,...

Artificial Lighting

Best Plants For Pots

Plant growth depends on a number of factors, two of which arc light and heat. In the simplest of terms, plants convert water and carbon dioxide into complex carbohydrates. In order to enable the plant to carry out this synthesis it has to be supplied with energy. The plant absorbs light through its leaves every day, and by a process known as photosynthesis converts it into energy. As some of the processes which take place in the plant are heat-sensitive, the ambient temperature is also a factor...

General Cultivation Of Pot Plants

It is not necessary to be a biologist to grow plants successfully, but it is much easier to understand the requirements of plants if you have some idea ofhow a plant functions. To grow plants in pots it is essential that you understand their requirements, because failure to provide the right conditions will usually produce a very disappointing result, and in extreme cases the plant will not survive. Light, air, water and heat, together with potassium, nitrogen, phosphorus and trace elements,...

The botanist monk Plumier is credited with discovering the first plants towards the end of the seventeenth century. As the plant could not be placed in any known genus, he decided to name the...

Automatic Watering

Unless you wish to be involved in the daily chore, and on sunny days the twice-daily chore of hand watering all your plants, which can be very time consuming if you have a full greenhouse, you would be very well advised to install an automatic watering system. The initial cost of this can be quite high but the advantage of having a satisfactory system is invaluable, not only from the saving in labour, but from the point of view of providing the most favourable conditions for the plants. One of...

Kalanchoe

This plant has become very popular in recent years, largely because it is possible to induce it to bloom for most of the year. Kalanchoes are shori-day plants, which means that they will only flower when they have experienced a period of short days. Their natural time for blooming is from mid-winter to mid-spring, but, if their exposure to daylight is restricted to a maximum often hours daylight with fourteen hours darkness in each twenty-four hour period, in about two to three months they will...

Temperature And Atmosphere

Plants are greatly influenced by temperature, because the complex chemical processes which are taking place in a plant both day and night are dependent on the amount of heat available. Plants vary very considerably in their heat requirements and here again their native habitat is usually a good guide. Alpine plants, for example, have very different needs to those of tropical plants. All plants have their maximum and minimum temperature requirements. The maximum temperatures are not often given...

It is the hybrids which have been developed from the stemless species that are grown as pot plants for the house and greenhouse. Of the stemless hybrids there are two main types, namely plants which form only one large leaf, and plants which form several leaves of similar size arranged in the form of a rosette. The...

Pelargoniums

Geranium Regal

The order Geraniaceae is divided into five tribes, one of which is called Geraniae, which in turn also has five genera, two of which are Geranium and Pelargonium. It is at this point that the reader can become confused by virtue of the fact that gardeners still continue to refer 10 pelargoniums as geraniums despite botanists changing the name of the genus well over a hundred years ago. We therefore have two very different types of plants both being referred to by the same name, which can...
