Blooming Griffinclaw was introduced to the game as a quest object in Version 7.8 August 1, 2006, unfortunately there is no message that can warn us about its appearance on the server.
His spawn time is randomly(can be 2 days in row) and spawn always after ss.
According to tibia fandom: you can take a sample of it every 20 hours, as long as you have an empty container in your hand and have not yet delivered one. If you try to harvest it again before 8 pm is over, you will receive the following message: "You just collected a fragile dish. At least wait for the rest of the plant to recover a little before gathering more."

The way is to check with your own character because a note from tibia famdom says the following: "Note that you must have started this search yourself to obtain the plant piece. You cannot use a different character."
It is only possible to collect one sample of this flower per day (per character).
Simplest route:

Blooming Griffinclaw it appear random time.
Remembering that a sample cannot be taken when it is dry.
I have a second level 80 character that I left camped on the spot and when the flower was blooming I went to get it with my character, Here is an example of a character from the world of Monza level 100.

Something interesting that I would like to share is that you can also find it when you want to kill Chief Deathbine in Port Hope, however when I entered the chief’s room they were in dry form, I believe it is not possible to collect them.
Image was from tibia royal but the fansite no longer exists anymore so the link doesn't work.
