Ruby Storm has been in my garden since 2016, has bloomed prolifically every summer. I have not accurately tracked first/last bloom though it seems to begin blooming in late June and continues until late July. Height is a little taller than the registered 26". Though I've never counted buds, it is clear the plant produces abundant blooms. It has formed a large clump which is now in need of division.
Added: This is absolutely one of my favorite daylilies! Love the colors, they don't fade in the sun. Scapes stand up well and have never required staking.
