Washingtonia Filifera Palmae Desert fan Palm Indoor House Plant

One of only two species of washingtonia, this palm is a tall, handsome plant with spiny leafstalks some 18in/46cm long supporting grayish green fan-shaped leaves up to 2ft/60cm wide. 

Washingtonia Filifera Palmae


The leaves are split about halfway down into many narrow segments, from the tips of which hang fine, dry, brown fibers.

In the wild, the tapered red-brown trunk is densely clothed in dead foliage, which is generally cut away on cultivated plants.

This fringe of dead leaves gives the plant its name of petticoat palm.

In their arid natural habitat, these palms are a sure sign of subterranean water, into which they send down long, deep roots. Since they thrive in hot, dry regions, the palms do well in centrally heated homes.

Washingtonia Filifera Palmae Desert fan Palm PLANT CARE


  • Bright light with plenty of direct sun. 
  • Warm or hot rooms, with a minimum of 50°F/10°C.
  • Water plentifully in the growing period, more sparingly in winter.  
  • Stand the pot on a tray of damp pebbles in very dry conditions. 
  • Apply a standard liquid fertilizer every 2 weeks in the growing period.

Tulipa Hybrids Liliaceae Indoor House Plant Guide

Tulipa Hybrids  Liliaceae Indoor House Plant Guide
Tulips are less commonly grown indoors than hyacinths or narcissi, but several varieties make good short-term pot plants. The early-flowering single and double types are best. 

Singles include scented yellow ‘Bellona’; red ‘Christmas Marvel’; salmon pink ‘Apricot Beauty’; and ‘Flair,’ which is golden yellow with red feathering. Good doubles include orange-yellow ‘Marechal Niel’; white ‘Schoonoord’; and rose pink ‘Peach Blossom.’

Also attractive are varieties of the low- growing Tulipa greigii, with mottled foliage, and T. Kaufmann IANA, the water-lily tulip, with wide, open blooms.

Treat tulip bulbs like those of hyacinth and narcissus and give them a cool, dark period after planting so they will develop an adequate rooting system. Plunge the pot in the ground outdoors under a covering of peat moss or enclose it in a black plastic bag and stand it in a cool place.

FACT FILE

ORIGIN Turkey; East Asia; hybrid.

HEIGHT To 2ft/60cm, depending on variety.

POTTING MIX Peat-moss-based or bulb medium.

REPOTTING Set bulbs close together in a pot in fall, with their noses just covered.

PROPAGATION Not practical for the amateur. Seedlings take 5-7 years to flower. Mature bulbs increase slowly by offsets.

KEEPING PLANTS Plant bulbs outdoors once flowering is over; it is not worth growing them for indoor use again.

PLANT CARE

  • Give bulbs a cool, dark period of about 10 weeks after planting; bring them into the light when they have about 2in/5cm of top growth. 
  • Keep in a bright location during flowering.
  • About 40 F/4 C for 10 weeks after planting; increasing gradually to about 55°F/13°C for flowering.
  • Keep the medium just moist at all times.
  • Give a balanced liquid feed every 2 weeks.

PUNICA GRANATUM Punicaceae Dwarf Pomegranate Indoor Plant

This compact and shrubby plant, with masses of l-in/2.5-cm-long evergreen leaves, is not difficult to care for. The tubular scarlet flowers, borne in summer, hang from the plant rather like those of fuchsia, but they are not as plentiful. 


 PUNICA GRANATUM Punicaceae Dwarf Pomegranate


If the blooms are pollinated with a soft brush, there is a good chance that small orange- red fruits will develop; these are not edible, but are interesting and attractive to look at.

House Plant Propagation Guide -Indoor Plant Propagation Techniques 2017

Most houseplants are bought as young or established plants from garden centers and nurseries. Even so, it is advisable to have a supply of young plants ready to replace the originals once they are past their prime.


House Plant Propagation technique 2017

You may also wish to have several specimens of a particular plant around the house, or to have spare plants to give to friends. If this is so, you needn’t buy more plants—it is quite easy to increase your stock of many specimens by a variety of means.


No specialised equipment is needed for propagating the easier species, although a seed tray with a clear plastic lid is cheap to buy and always worth having. 


A propagator with bottom heat will certainly help you to increase your stock of some of the more difficult subjects. Cuttings Probably the method most often used to increase houseplants is to take cuttings. 

House Plant Propagation technique 2017
A cutting is taken from the parent plant and encouraged to make its own roots (or sometimes shoots). Two types are used to propagate houseplants: stem cuttings and leaf cuttings.

Stem cuttings.

These are generally taken in spring or early summer. Snap a healthy young shoot, preferably without flower buds, from the parent plant. If it will not snap cleanly, use a sharp knife and cut just above a node.

The length of the cutting will vary, but it should have at least three or four pairs of leaves or leaf nodes (joints) between the tip and the base.
House Plant Propagation Guide 2017
Use a sharp knife to trim the base of the cutting to just below a node and remove the bottom leaves to give a clear portion of stem. Rooting powder is recommended for some species, athough most do just as well without it. If it is used, a light dusting of powder on the base of the stem is all that is needed.

Fill a shallow pot or seed tray with moist rooting medium and press it until it is firm. Scatter a thin layer of sharp sand on top. With a pencil or dibble, make holes in the medium for the cuttings, and insert them into it, making sure the base of the cutting is in good contact with the medium. Firm the medium lightly.

Space the cuttings so their leaves do not touch and water the completed tray or pot, using a sprinkler head on the can. Put a plastic cover over the tray and place it in a warm (68°F/20°C), bright location out of direct sun.


The time the cuttings take to root will vary, but eventually they will start to look fresh and to grow from the center. Thev can then be potted up individually.

Leaf cuttings

Some fleshy-leafed plants can be propagated from their leaves. The new plants are produced from either the plant’s leaf­stalks or from the veins.

Saintpaulias, the African violets, for j instance, are generally increased from leaf stem cuttings. With a sharp knife or razor blade, cut off a fully opened, healthy leaf at the base of the leafstalk. 


Trim the stalk to l-lV2in/2.5-4cm long, dip the base in hormone rooting powder, | and insert it, at an angle, into moist I rooting medium close to the edge of a small pot; bury about two-thirds of the stalk. Firm the medium gently and then j place the pot in a warm location in light | shade. 

Keep the medium just moist, and plantlets will appear within about eight weeks. Once they have grown into I strong young plants that can be handled easily, remove them from the pot, tease the plants apart carefully, and pot them individually. Saintpaulias will also root quite easily in water.

Some plants—streptocarpuses and begonias, for example—can be propaga­ted by leaf vein cuttings, which are taken in one of two ways.

House Plant Propagation Guide -Indoor Plant Propagation Techniques
Remove a healthy, fully formed leaf 1 cleanly from the parent plant. Cut the ‘ leaf horizontally into three or four sections, or split it lengthwise straight up the center of the midrib. Use a razor blade or sharp knife to make the cuts. 


If you cut the leaf into horizontal sections, make sure you know which is the top and which the base (the part nearest the leafstalk) of each section.


Dust the bases or the split midribs with rooting powder and insert them to about one-third of their depth in moist rooting medium in a pot or seed tray. Plantlets will be produced in the same way as with leaf stem cuttings.

Offsets

House Plant Propagation Guide -Indoor Plant Propagation Techniques

Several plants naturally produce small plantlets around the outer edge, which can be carefully removed and potted. 

This is an easy way to propagate succulents such as echeverias, bromeliads, some cacti, and bulbous plants. Wait until the offsets are a reasonable size and can be handled easily; remove the plant from its pot, then carefully

separate the offsets from the parent plant; you may need to use a sharp knife to cut through the rootstock. Keep as many roots on the offset as possible. 

If there are none, keep the newly potted offset in a warm, humid atmosphere and treat it like a cutting. Roots should form within a few weeks.

Buddleja madagascariensis Indoor Plant care Guide

The name of this plant is now correctly spelt Buddleja, but it is still generally known as Buddleia. It is a showy evergreen pot plant for a large, bright sunny room or a border plant for a greenhouse. Vigorous, with an upright habit, it can easily reach 6-10ft/1.8-3m or more in height.
Buddleja madagascariensis



It has 5-in/13-cm-long lance-shaped dark green leaves whose undersides are covered with a downy white felt. The small, bright yellow-orange flowers are borne in slender, pyramid-shaped clusters between late fall and spring. 

Unlike other buddleias, which have fruits like dry capsules, the flowers are followed by fleshy, berrylike purple-blue fruits.

PLANT CARE

  • Full sun or partial shade. 
  • Minimum temperature of 45°F/7°C in winter. 
  • Water moderately all year-round. 
  • Do not overwater, but do not allow the plant to wilt, since that can cause serious leaf loss. 
  • Feed every 2 weeks from spring to late fall with a dilute standard fertilizer.

Calliandra Haematocephala (inaequilatera) Powder Puff Plant

The ball-like flowers of this plant, which blooms in winter, are made up entirely of stamens, and the bright red 3-in/8-cm-wide “powder puffs” last for almost two months. The dark green foliage is divided into leaflets, each of which is about 2in/5cm long. 

Calliandra Haematocephala Powder Puff Plant image


In time the plant will develop into a bushy tree, but it will tolerate hard pruning, so can be kept to 2-3ft/60-90cm by cutting it back in spring. It can even be used as a subject for bonsai.

Calliandra needs moist air, bright light, and warmth, three conditions generally found in a sunroom rather than in a living room. But if these requirements can be met, it will do well in the house. Calliandra tweedii has smaller red flowers and its leaves are feathery.

Carica Papaya Caricaceae PAPAYA Indoor Plant

Widely grown in tropical countries for its fruit, the papaya makes an unusual ornamental foliage plant. The straight stem is usually unbranched and is topped by a cluster of long-stalked, deeply lobed leaves, which may reach up to 2ft/60cm wide on large plants.

 Carica Papaya Caricaceae


The fragrant trumpet-shaped flowers, borne in summer, are cream or yellow and up to lin/2.5cm long. Male and female plants in close proximity are required if fruit production is the aim, although bisexual plants that have both male and female flowers, such as Carica papaya ‘Solo,’ have been bred. When the papaya is grown as a houseplant, pollination by hand may be necessary.

 Carica Papaya Caricaceae PAPAYA indoor plant image

The 5-12-in/13-30-cm-long melonlike fruits are borne directly on the trunk, in the leaf axils. They are green and turn yellow or orange when ripe. The firm, fragrant flesh is yellow to pinkish orange.
