I grow every plant I use in my Design Blocks. If I can't ship to you, I'll source them from a grower I trust.
No pots, so no root binding. Every plant ships with free roots, ready to grow straight out into your soil.
Two sizes, in packs of 5 or 10. Start small in 3-inch cubes (I do), or a wrap for a head start.
It's still like ordering from me. Someone else does the growing.
I pick a substitute that does the same job in the Design Block. You see what changed and why.
