The delicate scent of lavender is composed of terpenes such as linalool, linalyl acetate and lavanduol. In our gardens, lavender attracts bees and butterflies and thus help protecting our biodiversity (4/4)

If you travel through France during summer, you can experience large fields covered with blue-violet flowers – quite a stunning view. Commercially, the species is grown to produce essential oil used in perfume and aromatherapy, which is known to have a calming effect (3/4)

Lavender is an herbaceous perennial shrub-like plant, well-known for its blue-violet inflorescences and cultivated for its beauty and scent. Dried flowers of common lavender (also called true lavender) have a sweet and palatable taste and can be used in cooking and baking (2/4)

PLANT OF THE WEEK – The beautiful flower with a fantastic scent: Lavendula augustifolia (Common name: lavender) by @MetteSrensen18. Lavender is from the mint family Lamiaceae. The genus consists of over 40 species and is native to most of Europe, the Middle East and India (1/4)

Another impressive feature of the Venus flytrap is the nervous system it has. After the hairs are activated, an action potential (nerve impulse) runs down to a central nerve and the leaf is activated to close (4-4)

If you touch a Venus flytrap with a stick or your finger it will not close. The leaf has a kind of short-term memory. The hairs on the leave must be touched twice in a short timespan to close. This is to prevent the leaf from closing if touched by raindrops, wind etc. (3-4)

The flytrap excretes a fragrance that attracts flies. A converted leaf with stiff hairs closes quickly around the fly. The more the fly moves the tighter this trap. Enzymes are excreted that dissolve the fly from the inside– a claustrophobic and painful slow death (2-4)

Bees with orange pollen on their hind legs could very well have visited a horse chestnut. By the way, do not confuse the horse chestnut with the sweet chestnut (castanea sativa), as it’s nuts are not edible but slightly poisonous (3-3)

Bees are attracted by the yellow dots and they will pollinate the flowers. After pollination, the colour changes to red, a colour that insects are not able to see and bees will not waste energy on these flowers (2-3)

PLANT OF THE WEEK – The tree that uses colour-signalling for pollination: Aesculus hippocastanum (common name: horse chestnut) by Eva Rosenqvist. Read the next post if you want to know why some of the white flowers have a yellow and some have a red dot (1-3)

Echinacea has been used as a "cure-all" herb to treat infections, wounds and influenza. Although not scientifically confirmed, it is known to stimulate the immune system. In gardens, purple coneflower attracts bees and butterflies and thus help protecting our biodiversity (2-2)

PLANT OF THE WEEK – the “cure-all” Echinacea purpurea (common name: purple coneflower) by @MetteSrensen18 @KU_PLEN. Purple coneflower is a flowering perennial from the daisy family. The large flowers light up the garden & the spines are decorative in dried flower bouquets (1-2)

The species is critically endangered in its native habitat, however its popularity will ensure its survival. While usually planted in parks and gardens, it is also suitable as an urban street tree as it is very tolerant to air pollution (6-6)

Metasequoia was named ‘dawn redwood’ – as old as the dawn of time. The Danish name “vandgran” (water spruce, a directtranslation of the Chinese name), is misleading as it is neither a spruce nor particularly moisture-demanding (5-6)

Since then, fossils of Metasequoia dating back more than 50 Myr have been found in Canada and Greenland. The abundance of fossils indicates that Metasequoia was a dominating element in the forests of the northern hemisphere (4-6)

The discovery of the dawn redwood in the early 1940s is a story in itself. In 1941, conifer fossils from an extinct genus were found in Japan. In China, an unknown tree species was found, which later was later classified as the extinct Metasequoia (3-6)

Dawn redwood is a deciduous conifer growing to more than 30 m high with a remarkable spongy and peeling bark. The rather soft needles are a light green until turning a warm bronze in the autumn (2-6)

The picture shows an African baobab, photographed outside Hoedspruit in South Africa. In the background to the left, a more than 2000-year-old tree has collapsed, the central trunk is degraded but the root and several side branches are still alive, growing along the ground.
