By the time we moved here six years ago, I was able to get five plants out of the two I had bought. But like Pippy Longstocking, they just grew and grew! Several years ago DIL M graciously took them off my hands and, WOW!, were they ever gaw-gee-ious!
hydrangeas...they are blue or pink according to the type of soil they're planted in...alkaline (sweet) gives pink flowers - acid gives blue flowers. So one shrub can be pink/blue or any thing in between. If you want pink flowers, treat 'em with lime in the spring - if you want blue, treat 'em with aluminum sulfate. Son L had some that were a fabulous deep, deep purple...he moved them, and sure enough, they turned a different color.
This kind of hydrangea does not get trimmed back at all because they produce buds for the following years bloom. I wait until the end of May to trim the dead stuff off - by then, one can see what is growing and what is not.
I L.O.V.E. me my Lime Lights! They certainly live up to their description, plus! They grow fast, bloom like mad and are a conversation piece. This year they really suffered from the hot, dry summer and look like this...
...instead of this.
(last summer's bloom)
Aren't the gorgeous? I kid you not...there were 8x12" single cluster bloom after bloom! After the first killing frost I merely snap the blooms off and put 'em on the burn pile - the shrub looks much cleaner that way. They can also be used in outdoor decorations.
Last year I used them this way for Christmas at the front door...
I placed a four-foot garden trellis in a pot, filled the trellis up inside with the dried lime light flower heads, twined a fifty light strand of lights around it and poked rose hips here and there, then twined a woody vine around the bottom. It really was lovely! The birds thought so to as they kept eating the hips. :)
