I get at 3 of these each year and dump them in large pots with just about anything.
These plants trail wonderfully and grow a multitude of branches, each of a different length.
The flowers are larger and for most of the summer, blooms prolifically.
For some reason, it seems to need a recharge in mid summer. The plant is still strong but the blooms almost stop.
Then it comes back in later summer and goes strong through early fall.
Definitely not a "self-cleaning" plant and most deadheads on my plants need much help to remove.
Does need a bit more water than most other plants I have and they seem to be adversely impacted by long stretches of 90+ degree sunny days.
I admit to buying bacopa under other brand names and while one or two have even larger flowers, none perform better than the PW plants.
Bacopa is an absolute staple in any pot and I highly recommend.
