What is called dahalia flower in sanskrit language?

There is no specific Sanskrit word for "dahlia" flower. Sanskrit is an ancient language, and dahlias were introduced to India from Mexico in the 18th century.

However, you could describe a dahlia using descriptive Sanskrit terms:

* "कन्दमूलोद्भवा" (kandamūlodhbhavā) - literally "born from a tuber," referring to its tuberous roots.

* "बहुदलिका" (bahudalikā) - meaning "with many petals," describing its characteristic flower structure.

* "रङ्गवती" (raṅgavati) - meaning "colorful," highlighting the wide range of colors dahlias come in.

You could also use a generic term like "पुष्पम्" (puṣpam) which simply means "flower."
