On the cover: Variegated plants tend to polarize; you either love or hate 'em. Regardless, the red lollipop Gyymnocalycium 'Hibotan' has drawn many to the hobby. The seedling on the cover, grown and photographed by Pavaphon Supanantananont, shows what can be done with such parents. As the characteristics are likely not stable, the image serves as a fine record of its transient beauty.
