Fred, I put L. Clockwork Orange in a 7 gallon pot because I was out of 5 gallons. It's really tall in that pot. I never even considered that using the bigger pots would put the height up so much but it raises them up about 6 inches higher than the 5 gallon pots. She has been so very pretty. She just nearly has a ruffle all the way around that is narrow but it looks so good being narrow. It highlights the rest of the petal instead of taking so much attention to the edge. I'm fast becoming a serious fan of her. She is on her fourth rebloom scape. I've never had rebloom like this and I love it.
I am curious about something. Does your plants of LCO have little seed pods? Mine are really small. They appear to be good, I haven't harvested any yet, just small. In fact, they look like a little bity fat pumpkin that has been squished down. The ribs are very defined. Man, they are hard to describe. I'll just have to get a picture of them later. Come to thank of it, I've got several other plants that have pods like this. Halloween Trick, my seedling "Elizabeth Salter x unknown" this one is an orange also. That's the ones that I can think of right now.
