Thank you!
The plants I have to set out right now are mature plants, but two of them are ones I've had trouble with in the past. They're also much more mature than they would otherwise be for this time of year here, so I'm trying to weigh-in that consideration as well.
Yeah...I'm not so sure that my gravel beds will provide enough water holding ability come summer, but we're usually so very wet and cold the rest of the year that I'm going as free-draining as possible. We shall see.
My seedling test plants of Stachys lavandulifolia and Lewisia rediviva survived the winter at least, now to see if they'll survive the (spring and) summer! If those two in particular can survive, I'm thinking that my winter drainage and year-round air movement should be good enough for most.
Hope you get rain soon!
