Product Description
Brunnera macrophylla 'Jack Frost' PP13859 (20)ct Flat
Common Name: Heartleaf Brunnera, Siberian Bugloss
The gold standard in Brunnera, and a must-have for shade gardens.
A sight to behold! The leaves of 'Jack Frost' are intricately detailed with a crackle-like finish. Though the leaves are dark green, they have a heavily frosted overlay which allows only the green veining to show through. From mid to late spring, baby blue, forget-me-not type blossoms are held in clusters several inches above the shimmering foliage. The effect is breathtaking.
Tip for southern growers and gardeners: 'Jack Frost' tolerates heat better than the older brunnera cultivars.
Brunneras are classic perennials that are treasured for their shade tolerance and lovely blooms. They make a fantastic groundcover, though the variegated forms may be slower to spread than the species. Try growing them in containers too so they will be close at hand when you want to snip a few blooms for a spring bouquet.
Brunnera is a woodland plant that should be grown in full shade and consistently moist soil in southern regions. In the north, morning sun is acceptable as long as the soil remains moist. They will grow the fastest and strongest in rich soil.
Little care is needed once Brunnera is established. Cut back the old foliage in the spring rather than in the fall; it will help to protect the crown during the winter. A winter mulch is also recommended.

Other Details
The most important part of the plant is its root system. Healthy roots are the foundation of a healthy, vibrant plant. The type of plug container used is based on the specific needs of the plants. Perennials offered as bare root traditionally perform better when planted as bare root.Planted in a specialized mix, potted plants have well established root systems. Top growth stage will vary depending on the current life cycle and time of year when shipped. In Winter and early Spring dormant plants may be shipped. Dormant plants may be planted right away, even before the last frost date.
Most bare root varieties are field grown for at least one season, though Hemerocallis and Hosta are grown for two seasons. The bulk of the soil is removed during the harvesting process and the tops of most varieties are trimmed back to the crown. They are graded, packed in shredded aspen or sphagnum moss and stored in freezers until ready to be shipped.
See our Container Sizes and Bare Root Perennials pages for more information.
Plant information and care is provided in the Overview section, Plant Genus Page and general information is provided in the Planting Care & Guides. Additional questions can be asked on each Plant page.
Plant Spacing: Using the maximum mature spread or width of a plant to guide spacing, ensures space to grow to full size. To fill an area sooner, plant them closer together. Just remember, future thinning or transplanting may be needed.
Water: Keep a close eye on newly planted perennials, especially throughout the first growing year. Most early plant loss is due to too much or too little water!

Small but healthy Jack Frost Brunnera
Ordered flat of 20 Jack Frost Brunnera plants. Plastic tags arrived first, somewhat concerning that this was perhaps all I was to get, but plants did arrive well packed in a box about a week later. Plants were a bit small, but all were healthy. Have been in the ground about one week. Let's hope all survive! Would have given five stars if communication had been better -- i.e. you will receive plant tags first, followed by the actual plants. Also, noting plant size (2" square pot size for each in multipack of 20) would have been nice as well.

Great Results Year after Year
This is my second batch of Jack Frost's from Blooming Designs. The first batch, from 2 years ago, is doing so well I had to have more. I love the flowers and the foliage.
