Spring is one of the four conventional temperate seasons, following winter and preceding summer. When it is spring in the Northern Hemisphere, it will be autumn in the Southern Hemisphere. At the spring equinox, days are approximately 12 hours long with day length increasing as the season progresses. Spring and "springtime" refer to the season, and also to ideas of rebirth, rejuvenation, renewal, resurrection and regrowth. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, monsoonal or cyclonic. Often the cultures have locally defined names for seasons which have little equivalence to the terms originating in Europe.
Campanula is one of several genera in the family Campanulaceae with the common name bellflower. It takes both its common and its scientific name from its bell-shaped flowers—campanula is Latin for "little bell".
Felicia alba is a species of flowering plant in the family Asteraceae. It is endemic to Namibia. Its habitat is sometimes degraded by livestock and agricultural crops, but its population is generally stable.
Lavandula angustifolia, formerly L. officinalis, is a flowering plant in the family Lamiaceae, native to the western Mediterranean.
Clematis is a genus of about 300 species within the buttercup family Ranunculaceae. Their garden hybrids have been popular among gardeners, beginning with Clematis × jackmanii, a garden standby since 1862; more hybrid cultivars are being produced constantly. They are mainly of Chinese and Japanese origin. Most species are known as clematis in English, while some are also known as traveller's joy, a name invented for the sole British native, C. vitalba, by the herbalist John Gerard; virgin's bower for C. viticella; old man's beard, applied to several with prominent seedheads; leather flower for those with fleshy petals; or vase vine for the North American Clematis viorna.
