Eucalyptus blue grows fast and fills a vase or arrangement with soft, rounded gray-blue foliage that lasts well when cut. The fine texture plays beautifully against bolder flowers and holds its color as it dries.

Start it now in a 4" pot and you'll have harvestable stems by late autumn. Plant it out after the last hard freeze if you want to experiment with overwintering, though most folks treat it as a seasonal filler.
