Yeah I think the craze for chillies is growing like Craft Beer. Masters had an impressive range of seedlings too. I've seen ranges of Trinidad Scorpions, Bhut Jolokia's, Naga's and other exotics that I never thought would be sold to the general public.
Looking forward to seeing Chocolate Trinidads in my garden this season. Yellow Ricoto, multi colored Habanero, just for the novelty of different colours ha.
I cant remember which of the Bunnings stores I got the seedlings from but if you treat them well they do very well. Get the individual potted seedlings.
Just don't disturb the roots when you de-pot them and transplant them into a big pot or bed etc. They love Organics so lots of compost and worms are the key too.
An organic tip is to dig out the hole for the transplant then toss in a handful of worm castings gunk from your own little worm farm. It will have worms in it too. Then place the de-potted chilli plant in and level the dirt, sprinkle the surrounding surface with Dynamic Lifter pellets. Mulch on top. Just keep moist with little watering, not too much.
