The plants are, in order from left to right:
Kumquat (Type of citrus fruit)
Chili pepper plants
Ginger and clementine (citrus) in the same pot.
Date palm (Deglet Noor)
Some kind of chili but I've forgotten what type.
Jalapeno. But the jalapenos have no heat, so they're basically just smaller bell peppers, which is slightly dissapointing. Good on cheese sandwiches though.
From left to right:
Some kind of chili
Some kind of Citrus. Maybe another kumquat.
Also, as a bonus picture. Here's what it looks like when I run my phase-modulated soundwave generated by code in an Arduino through a digital-to-analog-converter and into my oscilloscope.
