Kim, These are large growing phrags. The Patti MacHale is the smallest out of the trio - about 21 inches wide and tops about 15in. Leaves are thin in size.
The Phrag. Urgandiae is 2ft wide about the same height as the first. Thicker leaves sword like.
Phrag Grande is the largest 2f by 5in wide, tops to 17inches. Wide thick leaves, make room for this baby
Even though they are large growers, they are also very easy to grow. Not fussy about water quality as far as low ph and low calcium levels. I take my water right from the tap
Hank, No magic bullet here really. I give them catt lighting - 4tubes at 4ft length - T8 tubes. I feed 2x a month all year around. I keep these very moist in 70%chilean moss I add some filler of large perlite and bark.
The grande has been repotted 2wice in the last 9 months and it needs it again badly. The next pot size will be 8inches then time to divide.
BTW - This will be the first bloom for this grande
