Picked one of these up May 7 and left in original 5 inch pot for 10 days.
Plant has already grown 2 inches in height and the white flowers are in full bloom.
Definitely a vertical plant as mine is already about 12" tall.
At time of purchase, the foliage (especially lower leaves) were more a yellow color but have since evened out with the remaining foliage, which is a pale green.
The branches on this guy are thick and sturdy, enabling it to withstand the often higher than average winds my deck receives in spring.
While the plant flowers well, the flowers are located only at the top of each branch/stem so I would recommend planting in a large pot with other mounding annuals.
Very unique offering and I look forward to watching this guy reach the advertised height of 4 feet!
