No to running, It does outgrow small pots in a very short time, so just start big! The fruit is delicate, and is easily damaged by pests, so do your best to keep the buggers away!
The fruits are produced year round, so you can pretty much harvest through the entire period.
They grow to about an inch in length, some varieties much longer than they are wide. The fruits start growth slightly white and green, but progress to become a juicy red.
Yellow and Purple(ish) varieties are available too!
Due to the quick growth, these plants can easily be trained along the ground, or even as vines along a stake.
Sorry, but I misread your post the first time! I hope this better sums up what you wanted to know.
