Blárunni (Plumbago capensis) er á stundum ræktaður hér innan húss sem klifurrunni; hann er með ljósblá, pípulaga blóm í klasa á enda klifurstöngla. Blárunni var fyrrum tugginn til þess að lina tannpínu, enda er nafn hans á frönsku dentalaire, en hann örvar munnvatnsrennsli vegna þess hve beiskur hann er. Flestar tegundir innan gullintoppuættar (Plumbaginaceae) eru fjölærar, lágvaxnar jurtir, en þó eru nokkrar einærar og fáar klifurtegundir og runnar. Þær vaxa dreifðar um heiminn í flestum loftslagsbeltum frá miðbaugi til heimsskauta, en halda sig einna helzt á saltríkum steppum, sjávarfitjum og við hafsstrendur. Megin útbreiðslusvæði tegunda er þó við Miðjarðarhaf og í Asíu. Oftast eru blöð stofnstæð, þráðmjó eða spaðalaga og heilrend. Neðst á blöðum eru oft kalkkirtlar og þannig losar plantan sig við ofurmagn steinefna. Kirtlarnir gera tegundum kleift að lifa við háan saltstyrk. Lesa meira: [ Ссылка ]

Ceratostigma plumbaginoides is grown as an ornamental plant in temperate climates, valued for its late season colour. It is hardy down to −10 °C, but prefers a sunny, sheltered position in moist, well-drained soil. As it can become invasive, it is particularly suited to growing in a pot, or crevices in a dry stone wall. See more: [ Ссылка ]

The slender red stems of this low spreading, woody perennial are clothed in bright green leaves, which take on spectacular red shades in autumn before they fall. They are mainly grown however for their vivid blue flowers, which form in small clusters from late summer to mid-autumn. A superb plant for adding late colour to the front of the border, it will become drougt tolerant once established. See more: [ Ссылка ]

The generic name, Plumbago - derived from the Latin words plumbum ("lead") and agere ("to resemble"), was first used by Pliny the Elder for a plant known as μολυβδαινα (molybdaina) to Pedanius Dioscorides This may have referred to its lead-blue flower colour[citation needed], the ability of the sap to create lead-colored stains on skin, or Pliny's belief that the plant was a cure for lead poisoning.
