Hosta-Great for Shade  but Sometimes Holey!

If you’re looking for a great herbaceous perennial that has it “made in the shade”, there are numerous species and cultivars of Hosta to fill that need and enlighten the landscape.

Hostas are primarily grown for their diversity in leaf size, coloration, texture and shape, but the beauty of their flowers may also be a consideration when choosing a hosta. Flowers, sometimes fragrant, range in colors from white to shades of lavender and purple.

Our Plant Finder pages will introduce you to 101 hostas of various species and cultivars. To view, in the Advanced Search section of the Plant Finder, type "Hosta" into the genus box and then explore the results by using the “search” button at the bottom of the page.

While most hostas do well in the shady garden, another FAQ is whether there are any hostas that are tolerant of sun. The two linked answers will not only list some cultivars for you to consider, but contain some excellent growing tips as well.

Another FAQ is why hostas are sometimes holey, such as the ones in the picture.  There may be more than one answer to that question!

One Visual Guide on Hosta Problems will aid you in determining the cause of your holey hosta and introduce you to other insect, disease, and environmental conditions affecting this favorite perennial plant.

This week, try being the Plant Doctor and determine the cause of the holes in the pictured hosta. Here’s a little help-damage from animals such as rabbits and deer is exhibited by bite marks and left behind pieces of the plant.

Holes on the other hand, are most often caused by Slugs and Snails, Hail Damage, and/or other chewing insects. Oftentimes, if the damage is caused by an insect, the only way to know for sure is to catch the little critter in the act.

Now back to the holey hostas in the picture. After using the above resources from this website, what’s your diagnosis?
