(Perry D. Slocum 1948) This was one of the first introductions by Perry D. Slocum. The flowers are white with a brownish-yellow center. It is a floriferous variety and develops into a small colony of plants during the summer. It is also a heavy seeder and if you keep it in a heated tank you can even expect seedlings (they need warmer water to germinate than the plant needs to bloom). It is suitable also for small tanks or large barrels.
