How do I plant Pogostemon stellatus?

[Arrow1oo]

55 gallon planted, lightly stocked for now. I have root tabs and I dose thrive C fert.

Bought some pogostemon stellatus, not sure if it's the octopus kind or one of the more needy ones (hopefully not).

First time ever using stem plants as I usually go for rooted plants. How do I go about planting them, I've inserted a decent amount of stem into the gravel but the plants are naturally bending over, is this something I should try to fix?

Here's a pic:

I would let them settle in personally, just as they are.

I think I'll go with this, as long as they don't float up they'll anchor eventually right?

Yes, they will. Especially if they’re happy, they can drop roots in less than a week!
