最常見的牽牛花顏色是桃紅色、藍色、白色和紫色等。牽牛花的顏色十分豐富,有藍色、桃紅色、紫色、白色、黃色、紫紅色、緋紅色、粉紅色等等。其花呈漏斗狀,看上去像是一個喇叭,所以又稱為喇叭花。種植牽牛花一般在春天播種,開花時間通常在夏季。

  牽牛花的順應性較強,喜陽光充足,亦可耐半遮蔭。喜暖和涼快,亦可耐暑熱高溫,但不耐寒,怕霜凍。喜肥美疏松土堆,能耐水濕和干旱,較耐鹽堿。種子發芽適合溫度18-23℃,幼苗在10℃以上氣溫即可生長。

  作為一年生草本植物,牽牛花一般只在春季播種,播種40天就可以開花,它的花期比較長,最長可達100天左右,因此可以持續觀賞,而且由于可以變色,所以十分的美觀。

  牽牛在中國除西北和東北的一些省外,大部分地區都有分布。本種原產熱帶美洲,現已廣植于熱帶和亞熱帶地區。
