Vanilla Hazelnut
Vanilla Hazelnut fragrance for your Rainbow vacuum cleaners and Thermax vacuums. Suitable for any vacuum cleaner that uses water as the filter instead of bags.
Vanilla is a flavouring derived from orchids in the genus Vanilla. The name came from the Spanish word “vainilla”, diminutive form of “vaina” (meaning “sheath“), which is in turn derived from Latin “vagina“. [1]

The main species harvested for vanillin is Vanilla planifolia. It is a native of Mexico, though it is now widely grown throughout the tropics. Madagascar is the world’s largest producer. Additional sources include Vanilla pompona and Vanilla tahitiensis (grown in Tahiti).
Vanilla is a vine: it grows by climbing over some existing tree, pole, or other support. It can be grown in a wood (on trees), in a plantation (on trees or poles), or in a “shader”, in increasing orders of productivity. Left alone, it will grow as high as possible on the support, with few flowers. Every year, growers fold the higher parts of the plant downwards so that the plant stays at heights accessible by a standing human. This also greatly stimulates flowering.
The part of the plant in which the distinctive flavoured compounds are found is the fruit, resulting from the pollination of the flower. One flower produces one fruit. Vanilla planifolia flowers are hermaphrodite: they carry both male (anther) and female (stigma) organs; however, to avoid self-pollenization (which would tend to result in genetic deficiencies), a membrane separates those organs. Such flowers may only be naturally pollinated by a specifically equipped bee found in Mexico. Growers have tried to bring this bee into other growing locales, to no avail. The only way to produce fruits is thus artificial pollination.
A simple and efficient artificial pollination method was introduced in 1841 by a 12 year-old slave named Edmond Albius on Réunion, then a French colony, in the Indian Ocean. This method is still used today. Using a bevelled sliver of bamboo[2], an agricultural worker folds back the membrane separating the anther and the stigma, then presses the anther on the stigma. The flower is then self-pollinated, and will produce a fruit. The vanilla flower lasts about one day, sometimes less, thus growers have to inspect their plantations every day for open flowers, a labor-intensive task.
The fruit (a seed pod), if left on the plant, will ripen and open at the end; it will then exhaust the distinctive vanilla smell. The fruit contains tiny black seeds, which, in
ripe fruits, carry the vanilla flavour. These black seeds are the tiny black specks found in dishes prepared with whole natural vanilla. Vanilla planifolia seeds will not germinate in normal soil; they need a certain symbiotic mushroom.
Growers reproduce the plant by cutting: they cut sections of the vine with six or more leaf nodes, which have a root opposite each leaf. The lower two leaves are removed and this portion is covered in loose soil at the base of the support tree or post. The remaining upper roots will cling to the support and often will eventually also grow down into the soil. Growth is rapid under good conditions.
HAZELNUT
The Common Hazel (Corylus avellana) is a species of hazel native to Europe and Asia. It is typically a shrub reaching 3-8 m tall, but can reach 15 m on occasion. The leaves are deciduous, rounded, 6-12 cm long and across, softly hairy on both surfaces, and with a double-serrate margin.
The flowers are produced very early in spring before the leaves and are monoecious, with single-sex catkins, the male pale yellow and 5-12 cm long, the female very small and largely concealed in the buds, with only the bright red 1-3 mm long styles visible. The fruit is a nut, produced in clusters of one to five together, each nut held in a short leafy involucre (’husk’) which encloses about three quarters of the nut. The nut is roughly spherical to oval, 15-25 mm long and 12-20 mm broad, yellow-brown with a pale scar at the base. 
The nut falls out of the involucre when ripe, about 7-8 months after pollination. It is readily distinguished from the closely related Filbert (Corylus maxima) by the short involucre; in the Filbert the nut is fully enclosed by a beak-like involucre longer than the nut.
Common Hazel is used by a number of species of Lepidoptera as a food plant.
The name of the species, avellana is derived from Avellino, a place in Italy.
