Thunbergia grandiflora is an evergreen vine in the family Acanthaceae. [3] It is native to China, India, Nepal, Bangladesh, Indochina and Myanmar and widely naturalised elsewhere. [2] [4] Common names include Bengal clockvine, Bengal trumpet, blue skyflower, blue thunbergia, blue trumpetvine, clockvine, skyflower and skyvine. [4]

Description

Plants may grow to about 20 metres in height and have a long root system with a deep tap root, that can be as large as a small car. [3] The stalked, opposite leaves, which have a rough surface, are quite variable in shape. They may be triangular or ovate and the margins may be toothed, lobed or entire. Length is up to 200 mm and width is up to 60 mm, [3] which are typically smaller than the very similar T. laurifolia .

The blue to mauve flowers are about 8 cm across with a 4 cm long tube that is pale yellow inside. [3] These are followed by pods containing seeds that are ejected several metres upon ripening. Plants also reproduce from segments that are washed down watercourses. [3]

Cultivation

With a minimum temperature of 10–13 °C (50–55 °F), this plant is cultivated as a houseplant in temperate regions, [5] and has gained the Royal Horticultural Society's Award of Garden Merit. [6] [7]

The species has become a serious environmental weed in Australia on disturbed land along watercourses and in the wet tropics where it smothers other vegetation. It is commonly seen north of Sydney where it has been cultivated for many years. [3]

<i>Baptisia australis</i> Species of legume

Baptisia australis, commonly known as blue wild indigo or blue false indigo, is a flowering plant in the family Fabaceae (legumes). It is a perennial herb native to much of central and eastern North America and is particularly common in the Midwest, but it has also been introduced well beyond its natural range. Naturally it can be found growing wild at the borders of woods, along streams or in open meadows. It often has difficulty seeding itself in its native areas due to parasitic weevils that enter the seed pods, making the number of viable seeds very low. The plant has low toxicity levels for humans.
