Perovskia Blue Spike
Russian Blue Sage. Much admired tall fragrant first year flowering heirloom with long feathery deep sky blue flower spikes and contrasting silver green foliage. If it comes from Russia, then it's incredibly hardy and able to withstand heat, drought, cold temperatures and being knocked about. Older stems become woody so give it a good hard pruning as required.
Maturity second season from transplant.
