Continuing a thread on flowering plants that don’t thrive where I live now (in Palo Alto CA) but do thrive where I lived before (in Columbus OH); the key is needing cold winters, with at least some freezing.
Earlier (6/20/13)I posted about lilac (Syringa) — for which the so-called (unrelated but physically somewhat similar) “California lilac” (Ceonothus) can stand in:
they are both ornamental flowering shrubs, and Ceonothus can fill much the same function in landscape gardening in Mediterranean or semi-tropical climates as Syringa, most species of which thrive only in places with decidedly chilly winters.
Then more recently (4/24/14) I took up forsythia:
We don’t see much forsythia in these parts, because they require a winter freeze to flourish. They do grow in California and elsewhere in the West, but only in areas with cold winters; the Sunset New Western Garden Book enumerates these.
Now it’s peonies.
