The Hosta blue cadet size will grow to be about 16 to 18 inches tall at maturity extending a spread of 3 feet wide.

Grow across the United States in USDA growing zones 3-9. This hosta variety is an extremely cold hardy perennial that is easy to grow and low maintenance.

Spread a layer of mulch or organic matter in early spring to help retain moisture and encourage hosta flowers. An annual application of slow release fertilizer at the top of the root ball will benefit this type of hosta. You can divide hostas in late winter or early spring when they outgrow their planting site. Hostas are one of the only plants to withstand transplant shock, even hosta’s blue flowers are not affected.

Shipping information

Once your Hosta Blue Cadet Shrub order is placed, we will ship your plant(s) within seven business days year round unless during the checkout process you request otherwise in the space provided to do so.

Perfect Plants’ shipping specialists carefully package your plants using a proven packaging method that ensures your plants arrive healthy, colorfully alive and ready to flourish. We’ve coined the term ‘upside down box test’ and we do just that; we carefully package so that regardless of the direction your box is handled, it will not harm your precious plant that’s inside.

No shipping process is without a problem from time to time. On rare occasions some plants may experience some of the following during their transit: drooping, minor leaf-loss and/or minimal yellowing/discoloration, minor limb damage, etc. These instances are quite rare, but can happen when shipping plants in boxes.

Plants normally recover within a few weeks after planting. If a damaged box has injured your plant on the inside, please notify us within 5 days of receiving you package(s) by emailing us a photograph of the damage.

We always do our very best to ensure that your plants are packed and shipped in the safest, gentlest and most effective way possible.

Will my plants and trees look like the photographs?

Absolutely! Unlike other online nurseries, our photos are of actual plants and trees we’ve grown here, on our family operated nursery.

Your plants and trees may however not ship with flowers on them, like the photographs. This all depends on the time of year you buy your plant or tree. Crape Myrtle trees, for example, only bloom during the summer months, so if you purchase one during the spring or fall, they would ship without flowers. Once planted, your plants will grow and thrive giving you flowers for many years to come!

Pot Sizes

Pot sizes (commonly referred to in gallons) are shipped in the same size nursery trade pots which may vary in actual volume. Some plants may have been at the approximate pot size listed, but require excess dirt to be removed so that you will not be paying any additional shipping costs. This doesn’t happen very often though.

Shipping Fees

Our shipping charges are based on the value of your order and the destination it is being shipped. Please see the chart on the Shipping Info page to get an exact amount. We frequently have a free shipping promotion to help you save!



This low maintenance Hosta does best in full shade to partial sun. It does well with an average, well-drained soil that is moist but not soggy. This hardy plant does well in the winter, but spent flower shoots and any damaged leaves should be removed routinely.

The Blue Cadet Hosta should be planted 3-4 feet apart from other plants.


Dig a hole approximately twice as wide as your new plant’s root ball and deep enough so that the top of the root ball is equal with the ground level.

Loosen the root ball using a small garden spade or by hand. Breaking smaller outer roots can encourage growth into the new soil, but take care to not damage large primary roots.

Place the plant in the hole and ensure that it is situated evenly upright. Use the excavated soil to fill in around the root ball, using your foot to pack it in firmly. Thoroughly soak with a hose as you fill in the dirt. Take great care to not leave any gaps or air spaces around the root ball as this could kill the plant.

A 2-4 inch layer of mulch is strongly recommended to help retain moisture and discourage weed growth. Apply mulch over the entire planting area but keep away from the stems or trunk by a few inches. Ensure that the plant and surrounding soil is completely soaked with water.

To ensure the proper nutrients are available for the life of your Blue Cadet Hosta, our proprietary Perfect Plants Special Blend Soil and a once yearly application of Nutricote Total 360 Fertilizer are great considerations for your new plants!

A great shrub for shady locations. Planted under my oak trees and fits perfectly. Took a whole year for them to establish and start growing but now the hostas are looking gorgeous!

Phyllis B.

Perfect for my shade garden!

I am a lazy gardener. Perennials are great because I don't have to do too much maintenance. These hostas have been growing nicely :)


Great value. Easy purchase.
