Have never tried these plants, but when we needed an exotic for a show we read up all about them and set up a growing space with the right micro climate. If it says a certain temperature you really have to keep to it, no dipping at night or massive fluctuations. The right humidity and light levels are also essential, just putting them on the bathroom window sill is inviting disaster. I have made sprays from those automatic deodorising room spray gadgets. soldering a valve in the can and filling with water which will mist every five minutes if needed, a good heatmat that will warm the roots and growlight tubes from an aquarium.
This all sets you back a few quid and for me I could recoup from the customer. Pollination can be achieved with various devices, once we had a 'toy' from a sex shop with feathers stuck all over it that swung like a pendulum at a certain time in the night. It might be better for you to find an altenative herb than trying to explain to your neighbours what you are doing with a fluffy dildo in the middle of the night in the potting shed.
