  • Start a Lavender Farm, Produce Lavender Products, Start a business or build a career with lavender
  • A very practical course read, propagate, grow, harvest, make lavender products, research, all guided by expert tutors.

Lavender can be grown in most temperate and sub tropical climates; but you so need the right species for the right place; and if you want plants to live long; they need to be treated a particular way.

For the best commercial results, it may be better to have a temperate climate, relatively low humidity, and well drained alkaline soils.

LAVENDER TYPES AND CLASSIFICATION

Lavender is perhaps one of the most popular herbs grown worldwide. Thousands of acres of lavender are grown commercially, particularly in Europe, for lavender oil which is mainly used in cosmetics and soaps. The plants are ideal for hedges, garden shrubs and topiary. Dried flowers are used in potpourri, sachets, and other crafts. Dried flowers are also, sometimes used in cooking (eg. to flavour bread or biscuits).

Lavenders are in the genus Lavandula - there are approximately 30 species of lavender, many subspecies and numerous cultivars.

Lavender species are divided into the following 6 sections: Spica (also known as Lavandula), Stoechas, Dentata, Pterostoechas, Chaetostachys and Subnuda.
The first four sections are those most used in horticulture generally.

Spica (also referred to as Lavandula section)
Cultivars in this section are shrubs usually growing to 36” or more but also includes some dwarf varieties. The former name ‘spica’ refers to the spike-like nature of the flower heads.

Lavandula angustifolia syn L.vera, L.spica, L.officinalis (English lavender). A shrub to 1 metre tall; leaves linear lanceolate to linear oblanceolate to 5cm long to 6mm wide, whitish when young, becoming green; flowers approximately 1cm long usually purple.
• Lavandula alba   no botanical standing.  This is a white flowering variety of L. angustifolia.
• L. angustifolia ssp. angustifolia.
• L. angustifolia ssp. Pyrenaica
• Lavandula lanata
• Lavandula latifolia syn L. spica

There are many hybrids within this section.
L. X intermedia (hedge lavender) is a known cross between L. angustifolia and L. latifolia. This sub group within the spica section has many cultivars; the name Lavandin applies to these cultivars.

Note: When the parentage of a cross is known; you should always name place the cross breed name before the cultivar name ie. L X intermedia ‘Grey Hedge’. This is not the case when the parentage or one of the parents is unknown.
Lavandula X intermedia and L. angustifolia are the only two species recommended for culinary purposes.

Stoechas
Plants grow to around 90cm. and have broad round fertile bracts.
• Lavandula stoechas ssp. stoechas (Spanish/Italian lavender)
• L. stoechas ssp stoechas ‘alba’,
• L stoechas ssp. pendunculata - syn. L. stoechas ssp. cariensis,
• L stoechas ssp. sampaiana – a shrub to 1 metre tall; leaves linear to oblong – lanceolate; flowers usually purple.
• L. viridis 1m green/cream flowers, narrow green leaves

Dentata (sometimes included in Stoechas)
Plants have toothed leaf margins, inflorescence have reduced sterile bracts compared with stoechas. Spikes are elongated and sterile bracts appear about 1/3rd of the way down the spike.
• Lavandula dentata (French lavender) - a shrub between 30cm and 1 metre; Grey green linear oblong leaves crenately toothed to pectinate pinnatifid; purple flowers.
• L. dentata var. candicans

Pterostoechas
This less commonly grown group is distinguished by "winged flower spikes".
Shrubs have heavily branched stems. The flower spike is compact and usually without stems.
• Lavandula multifida – a shrub to 70cm, grey tomentose, leaves pinnately or 2 pinnately dissected, to 1.5 inches long; flowers blue violet.
• L. canariensis
• Lavandula pinnata – a shrub to 1 metre tall, leaves pinnate, to 5cm long; flowers lavender colour.
• L. pubescens
• L. abrotanoides

There are also some intersectional crosses i.e. Lavandula x allardii, L. x heterophylla.
Note: Lavandula X allardii  (Mitcham lavender) is thought to be across between L. latifolia and L. dentata.

Chaetostachys
This section, plants of which are not very common in cultivation, consists of herbaceous plants with branched peduncles and spikes. Stems and leaves are thick and do not resemble other species of lavender.
• L. bipinnata
• L. gibsonii.

Subnuda
A rarely cultivated section; Plants are herbaceous; the fertile bracts are alternate or spiral in arrangement. Adult plants are often devoid of leaves.
The following are the three most important species in this section.
• L. subnuda
• L. macra
• L. aristibracteata
