Where to find venomous tentacula in Hogwarts Legacy
Professor Garlick's Assignment 1 will see you needing to find and use venomous tentacula on an enemy, as well as using a Mandrake on multiple enemies at once. While there is a shop in Hogsmeade that sells both the plant and seed, there is another option to quickly finding what you need.
Depending on how much time has passed, the greenhouse furthest from the Greenhouse floo flame in Hogwarts is full of venomous tentacula you can pick, and that eventually grow back after being picked. I can't be sure exactly when they appear in relation to getting the initial assignment but it was these plants I used to complete it.
To find them head to the greenhouse furthest away from the floo flame, and go into the door on the right. Down the stairs you'll see six regrowing pants you can pick to top up your supplies.
Where is Dogweed and Deathcap in Hogwarts Legacy
You can buy both venomous tentacula plants and seeds from Dogweed and Deathcap in Hogwarts Legacy. You'll find the shop just up the northern end of Hogsmeade:
The plants you can just use and buy, like the ones you can find in the greenhouse, while the seeds will require access to the Hogwarts Legacy Room of Requirement and a Hogwarts Legacy large pot to grow it in. if you don't have a large pot you'll need to buy the requisite spellcraft from Tombs and Scrolls. However, given the six you can keep picking in the Hogwarts greenhouse you might want to just take those and save your space in the Room of Requirement.
