It works well in the right place. We have a number of different types. Keeping an eye on it once a year is sufficient and removing the dying flower heads before they seed is easy.
I have grown a pinky lilac cutting of Prunella which I believe is of the same family. so that it doesn't get out of hand. My instinct is to plant it in a container. I like it because it is "cottagey" I suppose and it reminds me of wildflowers. Thanks for the warning Mr Grinch
I really like it as it is a very tough little plant, but... It can be a bit of a thig if just left unchecked.. I just dig it out if it appears in the wrong place....
Where would you plant this ? This wouldnt be any good around perenials maybe more woody taller plants like tree's, roses etc ??
Its tough and if planted well to start with, will make itself at home. In a larger scale rockery perhaps? Somewhere where others would turn their nose up at the offer.
We have it in a number of places. Open areas, amongst perennials etc. I've just had a quick look through some of my older photos (got about 70,000 of them so not too easy to get to the ones I might remember) and grabbed these. This was in early March in a fairly open bed with perennial plants in it. The leaves usually look better later. These are the flowers on a larger leafed version - late April
I've not found them a problem with the perennial shoots that I have but they will stop new seedlings from growing. That's why they're a good ground cover plant.
