Uses of 'gustar'

[evanify]

I recently learned from my teacher that when I say I like 'verbs', I use gustar like this

Me gusta cantar y bailar.

I also learned that 'gusta' doesn't become 'gustan' even when it's like this,

Me gusta la flor y cantar.

Then what about this sentence? Which one is correct?
1. Me gusta las flores y cantar.
2. Me gustan las flores y cantar.

The second one is correct because the first noun encountered is plural.
