Gardeners' Notes:

Positive Caladria On May 7, 2012, Caladria from Greensburg, PA wrote:

This plant really got me started. I won it as a small centerpiece at a friend's shower. I potted it and put it on my porch where it received only a little morning sun. It thrived and grew to about 16 inches in diameter. I had to re-pot it once because it had outgrown its first pot, and it bloomed with bright pink blooms until frost. I tried to bring it indoors but it did terribly and died within a month.

I can't describe how much I loved this plant. It required babying in the form of watering well once a day. If it started to dry out even a little, the leaves and blooms would droop. The first time this happened I panicked, but an hour after I watered it, it was like nothing had happened. It became the centerpiece of my porch and inspired me to grow other flowers. I will definitely be picking up a few of these this spring and look forward to other colors.
