(Origanum majorana)

Marjoram grows as a mound type plant and are a perennial to around 12 inches tall.  Marjoram has glossy, pointed leaves that have a spicy taste and scent.  The plants are covered in summer with beautiful clusters of white or pink flowers. 

Plants are tender and do not survive in areas with heavy frosts.

Growing:  Except in frost free locations, sweet marjoram is best grown as an annual, started from seed indoors 6 weeks before outdoor planting.  Sow the seeds just below the soil surface. 

Marjoram tolerates poor soil, and prefers full sun and good drainage.  Space the plants at least 1 foot apart.

(Mentha species)

When it comes to growing herbs, few are as easy to propagate as mint.

The family of mints is large and easily identified by its characteristic square stems.  The leaves vary according to variety, but most are spear-shaped and serrated.  The two most common mints are  M. spicata (spearmint) and M.x piperita (peppermint), both are hardy perennials. 

They look similar, though peppermint has darker, glossy foliage and pink rather than white flower spikes, while spearmint has more rounded leaves. 

Mint plants grow to 3 feet tall and spread aggressively from stolon roots.

Growing:  Propagate by division and by root cuttings, since any section of root with a stem node will produce new feeder roots in moist soil.  Mint plants prefer full sun and humus rich, moisture retentive soil.   

NB: Growing herbs like mint is best done in a pot, away from over plants. If not contained, mints can be invasive and may represent a nuisance in the garden.  Space plants at least 3 feet apart. Luckily, Mints make excellent container plants grown in pots. 


(Tropaeolum majus)

Nasturtium flowers resemble pansies in that they have fairly flat faces, but grow in a wide variety of colour ranges that include bright orange, scarlet red, crimson, bright pink and apricot. 

The dark or bright green leaves are shaped like parasols and all parts of the plant including the seeds, leaves, stems and flowers are edible as a peppery flavoured garnish.

Growing:  Nasturtiums are a tender plant with large pea-sized white seeds which can be sown 1 inch deep directly into the garden.  

Nasturtiums can be frost effected where frosts are common.  The plants bloom best in full sun and also require good drainage. 

Dwarf varieties can be grown in the ground or in pots.

Uses:  Cooking, mostly salads.

(Origanum Vulgare)

Origanum Vulgare is the traditioanl oregano used in herb gardens because of its hardiness, attractive purple flowers and smooth, spear shaped leaves. 

Its flavour is not as intense as sweet marjoram or some of the more tender hybrid oreganos such as O.x marjoricum, commonly called Italian oregano. 

There are also some beautiful Oreganos which have landscape value such as O.vulgare “Aureum” a low spreading plant with botton like leaves that makes a beautiful edging or container plant.

Growing:  Oregano can be effected by frosts, so find a sunny position in the garden.  They are a perennial plant. 

Hybrid oreganos can only be propagated by cuttings.  Others can be grown by seed planted directly into the garden. 

Oregano plants will tolerate poor soils, but require good drainage. 

Uses:  Commonly used in Italian dishes.

Many people start off growing herbs with parsley seeds.

Parsley is a hardy perennial plant that grows to a height of around 30cm tall.  It can be cut back regularly to produce new foliage which is extensively used in cooking.  There are two common varieties a plain leaf and a curly leaf variety.

It is a shame that when people think of growing herbs, so few consider saffron.

The finest Saffron grows in Spain and Kashmir.  It is, by some distance, the world’s most expensive spice. 

A type of autumn blooming crocus, plants are grown from bulbs, which produce spiky green leaves in summer and flowers on bare stems in autumn. 

At the center of each cup shaped bloom is a pair of long reddish filaments.  These are removed by tweezers and dried in batches on screens to make a bitter flavoring valued in certain gourmet dishes.  The filaments are also the source of a deep yellow dye. 

Growing:  Saffron crocus prefers areas with longs summers.  The bulbs are usually available from mail-order sources in autumn. 

The bulbs can be grown in the garden or in pots.  Saffron requires a fertile well drained soil.

(Satureja montana)

Growing herbs like Savory s less daunting than exotic Saffron.

Although there are two kinds of savory grown in herb gardens (winter savory and summer savory), it is the summer savory that is the most pungent and useful as a seasoning. 

Unfortunately, it is not a very attractive plant, growing loose, upright stems up to 3 feet tall, with slender leaves.  Winter savory, especially the dwarf form, ‘Repens’ is more ornamental in appearance. 

It forms an attractive cushion just 6 inches tall and is covered with masses of white flowers in late summer. 

Both winter and summer Savory are hardy perennials.   

Growing:  Propagated Savory either by seed, division, or cuttings.  Seed can be planted in punnets and gown on to seedling stage. 

Plant Savory in full sun into a well drained soil, spacing the plants at least 12 inches apart.

Uses:  Seasoning in cooking.

Common sage is a clump forming hardy perennial with woody stems and decorative, gray green, lance-shaped leaves that appear to be blisted.

The leaves have a strong, camphor-like flavour.  In early summer, the plants produce spires of decorative blue flowers.

Growing:  Propagate sage from stem cutting and division.   Although it is perennial, plants rarely live beyond a third season, when they become brittle and fall apart.

They prefer full sun and well-drained soil.  Space plants at least 12 inches apart.  The variegated forms are especially good to group together in containers.

Uses:  Sage is a popular seasoning for poultry stuffing, sausages, stews, herbal sauces, hams and fish.  Store leaves dried in a screw-top jar.


(Rumex acetosa)

Sorrel is a hardy perennial growing in a clump of long broad wavy leaves that can be harvested as an edible green for most of the year, even during winter months.  In mid-summer the plants produce clusters of reddish flowers, which are followed by brown flaky seeds that persist on the stems a long time.

(Nasturtium officinale)

Watercress produces rosettes of succulent, heart shaped, glossy green, vitamin rich leaves and clusters of tiny white flowers. 

During winter and cool spring and autumn months the rosettes stay tight and low to the ground, but in hot weather they elongate and go to seed.  However, there is barely a day of the year that you cannot harvest fresh watercress as an edible salad green.

Growing:  Contrary to popular belief water cress does not need water in which to grow.  Although it thrives in shallow running streams, with its roots permanently covered in water, watercress will grow in any humus loam soil, mulched to retain moisture.  

Though watercress is easily grown from seed, direct sown into the garden during cool weather and lightly covered with soil, it is most easily propagated by dividing up an existing clump and transplanting it to a sunny location. 

Watercress also grows well in pots, especially if the base of the pots rests in water.

Uses:  Cooking, mostly salads.
