Katakana spelling is common for plant names; usually written in kana.
Kanji spelling is rare and mainly found in botanical contexts; learners should use kana.
ペチュニア is the direct loanword from English, while ツクバネアサガオ is the native Japanese name. Both refer to the same plant, but ペチュニア is more common in everyday conversation.
The name ツクバネアサガオ literally means 'shuttlecock morning glory', from 衝羽根 (つくばね, shuttlecock) and 朝顔 (あさがお, morning glory), referring to the shape of the flower. The exact historical derivation is uncertain.
