i bought some Lamium maculatum last year, both pink pewter and white Nancy, having seen some at my kids school and doing some research online. My reading led me to believe it could spread like crazy..exactly what I wanted as groundcover in between my young hydrangeas. The Lamium was all planted end of last summer, some 9" pots some larger.
now spring has sprung, the Lamium looks v healthy, with distinctly larger lighter leaves, however it stays in the clumps it was planted in. ive Buried some stems in the hope of encouraging it to spread but so far nothing. Just wondered if anyone else had a spreader, or have I been misled?
