Bunny Tails grows as a compact ornamental grass growing up to 20 inches high and about 1 foot wide. The blades are soft and about 1.5 foot in length. The ornamental value of this lovely grass is because of its fluffy, white oval flowers that start appearing in early summer. Bunny tails flowers assume tan color as they enter the fall season arrives. The flowers start to dry out at this time. You can keep them on the grass for winter interest. Stalks with dried fluffy flowers can also be removed and used in dry flower arrangement.

Unusual Caudiciform Plants – Fat Plants

Caudiciform plants is a large group of plants that form caudex – a fat stem or root. The caudex in most Caudiciform plants is prominent and gives these plants a uniquely unusual shape and character.

Caudiciform plants make excellent specimen plants. Take the example of Adenium obesum, Beaucarnea gracilis, Cycas revoluta, most Cyphostemmas, and Dioscorea elephantipes. Like other Caudiciform plants, these attractive plants form caudex to store water and food so that they can survive long spells of drought therefore these are generally low-maintenance plants.

How to take care of Caudiciform Plants / Fat Plants

Caudiciform plants do not require much maintenance. Because they are able to store water for dry periods, you do not need to water them regularly. During the months of active growth, water sufficiently only when the soil is completely dry. Avoid watering when the plant is hibernating.

Grow your plants is a well-drained soil and feed them when they show active sign of growth. With a little experience with caudex forming plants, you will understand that most of these plants quick adopt to the surrounding climate. You can grow them outdoors as specimen plants, indoor on a window sill, or in a greenhouse (if you live in a colder region). Generally, they prefer dry conditions and good exposure to the sunlight.

Types of Caudiciform Plants / Fat Plants

Caudiciform plants come in all sizes. Some grow into tall trees, some have shrubby growth, some of them are vines and some of them are small succulents. The size, location, and shape of caudex in most plants vary greatly. Therefore, these caudex forming plants are further grouped in four categories.

  • Phanerophytes: These Caudiciform plants form succulent base which appears prominently above the soil level. Most Adenias, Beaucarneas, and some Pachypodiums are good examples of Phanerophytes.
  • Chamaephytes are Caudiciform plants that form caudex at their base. The caudex in these plants may or may not be prominently visible. Dioscoreas belong to this group of caudex forming plants.
  • The caudex in Hemicryptophytes is usually formed below the ground but the growth is usually above the soil level.
  • Geophytes are caudex forming plants that form both their caudex and the growing point underground. Ibervillea is a good representative of this group.

Ornamental Shrub: Cotinus coggygria

Cotinus coggygria 'Royal Purple'
Cotinus coggygria or Purple Smoke tree as it commonly known is a wonderful ornamental shrub. I love it for its colors, and ability to grow in almost any soil and survive drought or a little neglect.

Cotinus coggygria is recognized by its purple leaves that change many colors throughout the fall season. While the season changes from summer to fall, you can spot purple, red-orange and scarlet colors in foliage. The beauty of this wonderful shrub is enhanced when its flowers pop to produce plum-like clusters of seeds. These plumes give this beautiful shrub a hazy look (and of course the common name, Purple Smoke Tree) that adds charm to its colorful foliage.

The Ultimate Guide to Designing Beautiful Xeriscapes

Though the word sounds complicated, Xeriscaping is a simple and practical technique of designing water-efficient landscapes. Xeriscaping involves preparation of soil, selection of plants and design of landscape layout to minimize the use of water.

In a nutshell, an efficient xeriscape is a low-maintenance, high impact and water-wise landscape.

Useful Tips for Designing Efficient Xeriscapes

Following are some basic pointers to designing an effective xeriscape:

Improve Soil

Soil is the first thing you should analyze when planning a xeriscape. Make sure that the soil is able to retain moisture by adding organic matter to the soil. See: Tips to improve sandy soil organically

Select the right plants

Select native plants; they are low on maintenance and do not usually need frequent watering. There is a wide variety of drought-tolerant plants that can be used in xeriscapes. See: 100+ xeriscape plants.

Design effective layouts

Design your xeriscape layout to ensure minimum waste of water. You can use terraced layout, pathways, and slopes to ensure that water can easily flow through your garden and irrigate most parts of the xeriscape.

Use planting techniques

Be creative when planting. Plants with similar requirements can be grouped together to ensure efficient use of water. Plant xerophytes on slopes.

Irrigate efficiently

Irrigate in evening or early morning to reduce evaporation. Contain rainwater for irrigating your xeriscape. Replace sprinkler system with drip irrigation system.

Mulch the bare soil

Use a lot of mulch. Topping up the bare soil with two to four inches of mulch prevents water evaporation, maintains an even, cool soil temperature and prevents the germination of weed seeds. The best time to apply mulch is in late spring after the soil has warmed, but before summer’s heat begins. A late autumn mulching helps avoid the alternate freezing and thawing of soil.

Suitable Plants for Xeriscapes

Selection of plants greatly depends on your climate. I have listed about 100 drought-tolerant plants along with their culture, growth requirements and USD zones here. You can also browse the following list of popular plants that can be used in most xeriscapes.

This lovely bush is characterized by knotted stem that bears large foliage of olive-green color. Each leaf is covered by velvety brown ‘hair’ underneath that make its felt-like surface. These succulent leaves assume triangular shape with crumpled edges. Because of their shape and furry shape, Kalanchoe beharensis is also known as Feltbush or Velvet Elephant Ear.

How to Grow Kalanchoe beharensis

Kalanchoe beharensis is native to Madagascar where it grows in warm and humid climate therefore it should be provided similar conditions to thrive well. In cold climates, it requires protection from frost and long spells of freeze. If you are growing it in areas that get a lot of frost, it is advised to move your plant in a greenhouse, or to a spot where it gets sufficient light but protection from frost and extremely cold conditions in winter.

Kalanchoe beharensis can be propagated from stem or leaf cutting. A mature plant can transform from a bush to a small succulent tree of 4 to 5 meters. Generally it is an easy plant to grown and maintain. Whether grown in a planter or ground, make sure that you water it only when the soil is completely dry.

Alliums: The Ornamental Onions

Alliums, commonly known as Ornamental Onions, are popular perennials among gardeners because of their graceful flowers and ability to grow in many different conditions. Most Alliums are characterized by their tall flower stalks (up to 3 feet) that stand like sentries with big, round flower heads (up to 5 inches). Their prominent flower heads make Alliums very useful for providing a nice and attractive background to low-growing bloomers in flower beds.

Allium globemaster

Growing Alliums should not be a big challenge even for beginners. They are drought-tolerant, resistant to pests, and low on maintenance. They also come in a wide range of variety in terms of heights, blooming period, and form and color of flowers. Alliums are grown from bulbs planted in the fall. Bulbs should be planted at a depth of four times the diameters of bulb. Alliums generally prefer a rich and well-drained soil under sunny conditions. If you are growing them in poor soil, feed them with a general fertilizer in early spring or top up the soil with a layer of compost [Also read: How to prepare your own compost].

Most varieties start blooming from late summer to early summer. Flowers, especially of late blooming verities, last longer. Both fresh and dry flowers make excellent addition to flower arrangements. As end of season approaches, leaves start straggling and should be cut back, if required. Once flowering is over, bulbs can be lifted and stored for the next harvest.

Popular varieties of Allium include:

Allium ‘Purple Sensation’ produces large (3 inches or more) purple flowers on tall (up to 3 feet) stalks.
