I purchased another coral porter weed online. One thing confused me the label said pink porter weed and that it's grows 2.5 feet tall and 2.5 feet wide. I thought the coral one could grow 5 feet tall and 4 feet wide. Are there more than one variety of the coral porterweed? Also it has been 10 days and my plants from hirt s are not growing rapidly. The tutti fruitti that has one stem left has not grown any other stems yet. The red kudos does not look to be growing yet. Are agastaches slow growers. They are both in quart sized pots.
