Go BACK my Lord, there's TWO of them.

As a "Hammer of the Scots" joke punch-line ends.
Last year there was "but one", unlike the Four Marys.
The Trilliums seem to be thriving. 
I took a closer shot this year, on account of the Kavalergaard having migrated "round the back" to more favourable climes. 
Out back, where I moved the Iris Kavalergaard it/they, also, now seems to have multiplied. It will, probably, get a look in too.

Retrospectively:- 
It's interesting that last year they weren't open by the 15th Apr.
This year both are open a touch over a week earlier.
