Brunnera macrophylla 'Jack Frost'

Plant details

Brunnera is an ideal plant to choose if you're looking for something a little more unusual for the spring garden. Throughout April and May, Brunnera 'Jack Frost' is covered with lots of small, bright blue flowers which look rather like forget-me-nots. These are complemented by the beautiful heart-shaped foliage which is a pale silver-grey with pronounced dark green veins.

To get the best results, grow Brunnera 'Jack Frost' in a moisture-retentive, humus-rich soil, where it will form lush attractive ground cover. It looks particularly striking planted in drifts in the woodland garden.

I got one of these last year (2011), and it's already a firm favourite of mine. I'm now on my second year with it and it's masses of piercing blue tiny flowers and silvery/green foliage really are a joy to behold.

I've got mine in a shady position as it prefers this and it basically looks after itself. I was a bit concerned at early spring though, as when I went to cut it down to ground level there was nothing there! But soon enough it started to grow again, and it's a remarkably fast grower I have to say - you can see the change daily.

Once the flowers have finished it's still a really nice plant to look at because of its interesting foliage. I had a bit of chomping on it from snails last year, but only minimal damage was done. It likes a drink as well so on hot days or dry periods it needs a nice glug to pep it up again.

I love this plant, if you have a shaded spot that needs something to liven it up then I really would recommend it.


I have several of these now, in various leaf colour varieties and think they are wonderful. However, you should not call them forgetmenots, the flower does look similar but it is a totally different group of plants. The don't have the potential to be come a nuisance in the way that myosotis can do. Brunneras appear to be quite hardy, I had two the year of the very long hard winter, 2010-11, and they both survived, rather to my surprise. They looks good for most of the year too, always a bonus, especially with a flowering plant.
