Irritating Plant of the Month March 2017 - the Hyacinths

I nearly could not think of a plant that was irritating me this month.  I almost decided to give this month a miss (my blog, my rules), but then when I thought about it I thought of a plant I could name and shame, except possibly not so much of the shame really, more of a mild tutting at.
I present to you......
.... the hyacinths I planted in the Wild Garden a couple of years ago.  This one is Peter Stuyvesant, rather fab isn't it?  I actually cannot bear hyacinths indoors, I find the smell suffocating; but when visiting Evenley Wood back in 2014 I was reminded how I love them outdoors.  I used to have some in my garden at Nottingham and it was a nice memory to return to.  So I duly purchased some hyacinths to plant the next autumn and they flowered reasonably well the following spring....
.... and then disappeared.  I thought they were dead.  I looked for them but nothing appeared so I mourned them briefly and moved on.
This year, pop, there they are.  Not all the ones I planted have reappeared but a few have.  Enough to encourage me to buy some more.  At least this time I will know not to give up hope in year 2, they clearly like a sulk.
So why are they irritating if they have flowered this year?  Well where were they last year?  That is why they are being tutted at but also gently encouraged as I am very pleased to see them.
What plants are currently irritating you with their behavior in your gardens?  Do let me know.
