A few years ago, I gave my wife an Alice-in-Wonderland present: a rose bush with red and white roses.*
After a year or so, the white roses predominated, and we saw only the occasional red rose, then just some pink flecks on the white roses from time to time.
Then last year some shoots started zooming up. I installed a garden arch to support them, and they've been quite vigorous in the rains of the recent season, growing more than double the height of the previous years.
And then: a solitary red rose in the middle of the trellis, isolated high above the bush of white roses. Quite a sight. The photo below is an indication, but doesn't do it sufficient justice.
