blossom
verb (used without object)
4. to flourish; develop (often followed by into or out):
a writer of commercial jingles who blossomed out into an important composer.
(Dictionary.com)
The writer is not simply talking about the conversations they had, but about the conversations that developed. The nuance is that blossom is something flowers do. In your example, the verb blossom is used figuratively and that usage could be considered poetic, or artistic.
The on-line Oxford Dictionary defines 'blossom' in meaning 1.1. as:
Mature or develop in a promising or healthy way Oxford - Blossom
So the speaker does not just mean that these two people had a conversation, but that the conversation went beyond trivial day-to-day matters and went into deeper, possibly more personal, areas. The use of the word 'blossom' indicates that the speaker, and possibly the person they were speaking to, considered that conversation to be healthy and productive, much as a healthy plant blossoms by producing new growth and flowers.
