What is it?

I've no idea Kat ,I don't recognise ,it hopefully someone else will be able to tell you ....

I don't know either, but it's rather attractive!

Hi Katarina, it looks like clover to me, {or shamrock}, but with a touch of chlorosis, usually caused by iron deficiency in soil which is lime rich, Derek.

Absolutely perfect answer, Derek. Thanks to you I checked the Slovak translation of shemrock and found there are several types of this plant, so it is probably one sort. Thank you very much. Are you professional in gardening? I mean, because you knew that thing about lime and iron.

Hi Katarina, I used to be a professional gardener, until I had to finish work, to lookafter my disabled wife, but now I am officially retired, lol, I was gardening from the age of 5 years, and thoroughly enjoyed every minute, Derek.

Nice to meet you.

Thank you katarina, and nice to meet you too, Derek.
