    Nursery contributed plant descriptions

    The all-season flowers of this tough little workhorse are a deeper, brighter blue than the usual pastel; so pretty between pavers, as a lawn substitute, in pots or walls; 6-12't x 24"w, may need shade in heat. S-PSh/M

    A steppable groundcover with tiny, green leaves and, in this form, dark blue, star flowers from late spring to frost. Great for filling in between pavers or over the sides of containers. Evergreen in mild winters. To only 2" or so tall spreading to 18-24" wide. Full sun in coastal climates but afternoon shade or dappled shade inland. Needs summer water. Frost hardy to -20F, USDA zone 5. (AKA: Laurentia fluviatilis, Lobelia fluviatilis, Pratia pedunculata and Pratia puberula!)
