This little silver foliage speedwell is one that I haven't tossed yet .. I have had others that fall prey to the dreaded powdery mildew and look sick .. not nice ! But the silver foliage and the hardy nature of this little gem has kept it at home in my garden. It has lovely blue spikes and even when they are nipped off the foliage still is an attractive feature !
