Lavander



The Lavenders Lavandula are a genus of 39 species of flowering plants in the mint family, Lamiaceae, native to the Mediterranean region south to tropical Africa and to the southeast regions of India. The genus includes annuals, herbaceous plants, subshrubs, and small shrubs. The native range extends across the Canary Islands, North and East Africa, south Europe and the Mediterranean, Arabia, and India. Because the cultivated forms are planted in gardens world-wide, they are occasionally found growing wild, as garden escapees, well beyond their natural range. Because Lavender cross-pollinates easily, however, there are countless variations within the species.



The most common "true" species in cultivation is the Common Lavender Lavandula angustifolia (formerly L. officinalis). A wide range of cultivars can be found. Other commonly grown ornamental species are L. stoechas, L. dentata, and L. multifida.

Lavandula x intermedia or "Lavendin" is the most cultivated species for commercial use, since its flowers are bigger and the plants are easier to harvest, but Lavendin oil is regarded to be of a lower quality.



Lavenders are widely grown in gardens. Flower spikes are used for dried flower arrangements. The fragrant, pale purple flowers and flower buds are used in potpourris. Dried and sealed in pouches, they are placed among stored items of clothing to give a fresh fragrance and as a deterrent to moths.

The plant is also grown commercially for extraction of lavender oil from the flowers. This oil is used as an antiseptic and for aromatherapy. Lavender is also used extensively as herbal filler inside sachets used to freshen linens and discourage moths from closets and drawers. Dried lavender flowers have become recently popular used as confetti for tossing after a wedding.




The ancient Greeks called the lavender herb nardus, after the Syrian city of Naarda. It was also commonly called nard.

Lavender was one of the holy herbs used in the biblical Temple to prepare the holy essence, and Nard is mentioned in the Song of Solomon (4,14)

nard and saffron, calamus and cinnamon,
with every kind of incense tree,
with myrrh and aloes,
and all the finest spices.



During Roman times, flowers were sold for 100 denarii per pound, which was about the same as a month's wages for a farm labourer, or fifty haircuts from the local barber. Lavender was commonly used in Roman baths to scent the water, and it was thought to restore the skin. Its late Latin name was lavandārius, from lavanda (things to be washed), from the verb lavāre (to wash). When the Roman Empire conquered southern Britain, the Romans introduced lavender.

Daylilly



Daylily is the common name of the species, hybrids and cultivars of the genus Hemerocallis (pronounced /ˌhɛmɨroʊˈkælɪs/). These flowers of this plants are highly diverse in colour and form, often resulting from hybridization by gardening enthusiasts, the thousands of registered cultivars are appreciated and studied by international Hemerocallis societies. Once considered part of the Liliaceae family, such as Lilium (true lilies), the genus name was given to the family Hemerocallidaceae in later circumscriptions.



These plants are perennial. The name Hemerocallis comes from the Greek words ἡμέρα (hēmera) "day" and καλός (kalos) "beautiful". The flowers of most species open at sunrise and wither at sunset, possibly replaced by another one on the same stem the next day. Some species are night-blooming. Daylilies are not commonly used as cut flowers for formal flower arranging, yet they make good cut flowers otherwise as new flowers continue to open on cut stems over several days.



Originally native from Europe to China, Korea, and Japan, their large showy flowers have made them popular worldwide. There are over 60,000 registered cultivars. Only a few cultivars are scented. Some cultivars rebloom later in the season, particularly if their developing seedpods are removed.



Daylilies occur as a clump including leaves, the crown, and the roots. The long, often linear lanceolate leaves are grouped into opposite flat fans with leaves arching out to both sides. The crown of a daylily is the small white portion between the leaves and the roots, an essential part of the fan. Along the flower stem or scape, small leafy "proliferations" may form at nodes or in bracts. These proliferations form roots when planted and are the exact clones of the parent plant. Some daylilies show elongated widenings along the roots, made by the plant mostly for water storage and an indication of good health.



The flower consists of three petals and three sepals, collectively called tepals, each with a midrib in the same or in a contrasting color. The centermost section of the flower, called the throat, has usually a different and contrasting color. There are six (sometimes seven) stamens, each with a two-lobed anther. After pollination, the flower forms a pod.



The common Daylily is currently awaiting listing as a noxious weed. While sometimes planted due to their ease of growth and the fact that they produce a flower, non-clumping varities of daylily can quickly overrun a garden. Once established, it is difficult to remove runner daylilies from the yard.
