Tree Peonies Putting on a Show

There are three main types of peonies, herbaceous peonies, tree peonies, and intersectional peonies. Herbaceous peonies die back in the winter. Tree peonies lose their leaves in the winter, but keep their woody branches. And intersectional peonies are hybrid crosses of the first two and these peonies die back just like herbaceous peonies. In general, the flowers on the herbaceous peonies are smaller than those of the intersectional and tree forms, while the foliage is similar.

Tree peonies, with their large flowers and attractive upright mounded habit, make for a stunning focal point in almost any garden. They thrive in full sun or in part shade. We have one in our hosta ravine that is receiving mostly shade, and it is looking outstanding. They aren’t too fussy about a specific soil type either, but moist and well drained is preferred. Tree Peonies take some time to mature, but once they really start to put on some size, you’ll be thrilled that you had the foresight to get one into your garden. This year has already seen many of our tree peonies produce an abundance of gorgeous flowers and we are eagerly awaiting the blooms of all the others.

Pruning Hydrangeas and Other Shrubs

Hydrangea paniculata 'Vanilla Strawberry'

We hope to see you Saturday morning at 10 am for this free workshop. Spring is the time to prune most hydrangeas. However, different families or groups of hydrangeas have their own pruning requirements, so it pays to know which type of hydrangea you have. Rich and Dave Hornbaker will demonstrate proper pruning techniques for hydrangeas and other shrubs.

Great Hosta Combo

Which hostas look good together? The answer is of course subjective and will depend on a variety of criteria, including size, color, amount of sunlight, etc, but one combo that works well in most gardens is that of Halcyon, June, and First Frost. All three hostas, in their own right, are beautiful specimens. Both First Frost and June were named Hosta of the Year in 2001 and 2010.. Their growth rate can be a little slower than others, but these three hostas are as hardy as they come, and have nice thick, durable leaves that are still looking good well into late fall. Their colors work well with one another for good reason. Both June and First Frost are sports of Halcyon. Plant these three hostas in your garden and you will be glad you did.

Picks of the Week!

As we spend our days here at the nursery, we would love to talk to each and every customer that visits.  But we know that isn’t always possible.  The Picks of the Week will be a great opportunity for us to share with you our suggestions for good, reliable plants we think you should know about. We hope it’s the next, best thing to speaking to you in person!

Amelanchier 'Autumn Brilliance' in brilliant fall color

My pick of the week is Amelanchier x grandiflora ‘Autumn Brilliance’, the common name for which is Apple Serviceberry.  I especially like it in its multi-stemmed form, although we also carry a single stem tree form.  ‘Autumn Brilliance’ forms a small tree around 20-25’ tall and wide.  Delicate white flowers appear in fleecy racemes in early spring.  The small leaves allow filtered light to penetrate through to the ground, and then turn a wonderful mix of red, brick and orange in the fall.  The little fruits are loved by birds, which will clean the tree of fruit very quickly in the fall.  Even the shiny, speckled bark is interesting.  Serviceberry can grow in full sun or part shade, is very hardy in this area, and is virtually trouble free.    –Rich Hornbaker

Taxodium distichum 'Peve Minaret'

My pick of the week is Taxodium distichum ‘Peve Minaret’ – Dwarf Bald Cypress.  If I could have a pick of the year, this might be it. It just seems to scream, “Hug me! I’m awesome!”  I have always loved Bald Cypress trees. Old growth Bald Cypress, whether they are in the swamps of Florida or at the arboretum down at U of I, are magnificent specimens. They have a unique, prehistoric look to them that demands attention. To be able to shrink that magnificence into a cute, little, huggable dwarf form that fits well into almost any residential landscape is something that should be celebrated. This dwarf Bald Cypress is one tough little tree, too. It tolerates wet, clay, poorly drained soils, which makes it one of very few specimens that do so. Use it as a patio tree or along side a foundation for some vertical interest. Its needles turn a rusty orange in autumn before they fall, which gives it some seasonal interest as well.    –Dave Hornbaker

Euphorbia ‘Bonfire’

My pick of the week Euphorbia ‘Bonfire,’ a newer variety of Cushion Spurge, is one of the most colorful sunny perennials I’ve seen.  In late spring, glowing yellow bracts (the leaves surrounding the insignificant true flowers) are as eye catching as any bloom.  And the foliage is just as colorful, too!  The top growth is a combination of deep purple, red and orange while the new undergrowth is green, and then the whole mound deepens to burgundy and then becomes a rich red in the fall.  Grows to 12”-18” with a spread of 30” and will grow in full to partial sun.  This picture shows one in my yard on the north side of the house.  The foliage color is best in a sunnier location.   -Molly Hornbaker Blogg

Frost Damage on Hostas

Last week, we noticed that a majority of our potted hostas out in retail had significant frost damage. We think the extent of the damage was worsened by the timing on our irrigation system. Sprinklers run from midnight to 6:00 AM, one section at a time, for 30 minutes. Some hostas were worse off than others. The hostas that were given more time to dry off before the coldest hours of the morning fared better than the ones that were watered right before the temperature dipped below freezing.  It is important to keep the soil nice and moist when trying to prevent frost damage, but droplets of water on a leaf’s surface is something that should be avoided. Thankfully, the hostas back in our stock houses were still looking great, so operation ‘Hosta Swap’ was put into action. There were some varieties that only had a few leaves showing frost damage, so these were cleaned up by simply removing the damaged leaves. Most everything else needed much more attention. We cut the foliage all the way back on a majority of the hostas and replaced them with healthy ones. In a few weeks, the hostas we cut back will have sent out new leaves and will be ready to return to the sales bench!

The following are some tips to consider when trying to prevent frost damage on any plant:

  • Cover the plant. Things often used to cover plants include sheets, blankets, buckets, mulch, leaves, etc. If you are using a sheet or blanket, it is best to use some sort of supporting structure to avoid contact with the foliage.
  • Move container plants into the garage or onto the porch.
  • Keep the soil moist. A healthy plant is much more likely to survive a hard frost than an unhealthy plant. Keeping your plants well watered before a frost not only ensures you have a happy, healthy plant, but also creates humidity around your plant, which helps buffer a dramatic change in temperature.
  • Don’t prune or cut back frost damaged foliage until the danger of another frost has past. Pruning too early can stimulate new growth which is tender and even more susceptible frost damage.
