Ruby Tear Drops Colorado Blue Spruce is a stunning blue dwarf Colorado spruce. Drama unfolds in spring when dozens of ruby-red cones emerge from each branch tip, even on young plants! Cone color lasts for over 2 months! Add its low, globose growth habit and this is a spring-summer showstopper. Excellent, deer resistant choice for small areas like rock, urban, or balcony gardens, in mixed borders, containers, or as foundation plantings. Does best in full sun and grows in most soil types and thrives in well-drained soils with moderate water needs once established.
