A flower stem guide is secured to a diametrical slot in the cover and projects inwardly into the liquid. The guide is triangular U-shaped unit defining a base wall in spaced relation to the opposite jar wall. The vertical edge of the guide sidewall projects inwardly. A guillotine cutting unit includes a cutting support blade secured to the lower inner end of the guide and a guillotine blade secured to a shaft journaled in the cover, with the guillotine blade abutting the edges of the U-shaped guide. The guillotine blade is resiliently supported on a shaft journaled in the cover for movement past the support blade to sever the stem under the protective liquid. The shaft is manually operated or connected to a small solenoid on the top of the cover.
