Botaaniline kirjeldus
Lilltubakas on dekoratiivne õistaim, mis kuulub tubaka perekonda ja maavitsaliste sugukonda. Lilltubaka vars on püstine, harva harunev. Leht on ovaalne või elliptiline terve servaga teritunud tipuga lihtleht, mille alusel paiknevad hõlmakesed ümbritsevad vart. Lehed paiknevad vahelduvalt. Taime ülemises osas paiknevad lehed on elliptilised, terava tipuga. Kogu taim kaetud näärmetega, mis annavad selle pindadele kergelt kleepuva, sametja tekstuuri. [1-3]

Õisik on lihtne kobar. Õied on aktinomorfsed, kaheli õiekattega, viietised. Nii tupp- kui ka kroonlehed on alusel kokku kasvanud ja moodustavad kellukja pika putke. Tupplehtedest moodustunud putk on kroonlehtedest moodustunud putkest kolm korda lühem. Kroonlehed otstest teritunud, ümarad või pügaldunud (sõltuvalt kultivarist). Tolmukaid on 5, tolmukaniidid on pikad, kuid tolmukapead ei ulatu õiekroonist välja. Tipust neljaks jagunev emakasuue paikneb pisut kõrgemal kui tolmukad, et soodustada risttolmlemist. Õite värvus varieerub rohekast, valkjast kuni tumapunase ja lillani. Esineb palju kultivare, mille õite värvus ja suurus varieerub. Vili on küpsedes avanev neljaosaline kupar, milles on palju pisikesi seemneid. [1-3]

Levila
Lilltubakas ehk Jasmiini tubakas on pärit soojemast parasvöötmest Lõuna-Ameerikast ja teda kasvatatakse dekoratiivtaimena. Lilltubakal on palju kultivare. [4]

Toime ja  kasutamine
Taim sisaldab nikotiini, millel on organismi stimuleeriv toime. Nikotiin on ühtlasi tuntud ka insekitsiidina. Taim leiab laialdast kasutust iluaianduses. [5]

Botanical Description
Flowering tobacco is a decorative flowering plant that belongs to the tobacco genus and the nightshade family. The stem of flowering tobacco is upright and rarely branched. The leaves are simple, oval or elliptical with entire margins and pointed tips, with lobes at the base that wrap around the stem. The leaves are arranged alternately. The leaves in the upper part of the plant are elliptical with pointed tips. The entire plant is covered with glands, giving its surfaces a slightly sticky, velvety texture. [1-3]

The inflorescence is a simple raceme. The flowers are actinomorphic, with two whorls of floral parts, and pentamerous. Both the sepals and petals are fused at the base, forming a bell-shaped, elongated tube. The calyx tube is three times shorter than the corolla tube. The petals are pointed, rounded, or notched at the tips (depending on the cultivar). There are five stamens with long filaments, but the anthers do not extend beyond the corolla. The stigma, divided into four parts at the tip, is slightly higher than the stamens, promoting cross-pollination. The color of the flowers ranges from greenish, whitish to deep red and purple. There are numerous cultivars with varying flower colors and sizes. The fruit is a four-part capsule that opens upon maturity, containing many tiny seeds. [1-3]

Habitat
Flowering tobacco, also known as Jasmine tobacco, originates from the warmer temperate regions of South America and is cultivated as an ornamental plant. Flowering tobacco has many cultivars. [4]

Effects and Uses
The plant contains nicotine, which has a stimulating effect on the body. Nicotine is also known for its use as an insecticide. The plant is widely used in ornamental horticulture. [5]
