What to plant around hostas

'Blue Mouse Ears' is a small, rounded-leaf choice; 'Sum and Substance' belongs to the giant group. 'Halcyon' offers medium-sized, blue-green foliage. Check the label for the exact variety's mature spread rather than spacing every hosta alike. If an inherited hosta has no name, wait until its leaves have expanded before deciding what fits beside it.^{3Source 3Hosta 'Blue Mouse Ears'NC State Extension,2Source 2HostaNC State Extension}

Measure from the plant's center when laying out its future width. For a variety expected to spread 3 feet, mark a circle reaching 18 inches from the center in every direction. Add the clearance you want beside a walk, then choose companions for the space outside that outline.

Shade doesn't guarantee moist soil. Under a tree or roof overhang, check moisture before copying this combination. Hostas generally grow best with filtered light and moist, well-drained soil; adding thirstier neighbors won't solve a dry bed. Don't cut major tree roots or raise the soil over them to make room for companions.^{1Source 1HostasUniversity of Minnesota Extension}

A bed can also be shady at breakfast and sunny all afternoon. Record its direct sun before buying more shade plants. For a different climate, take the desired roles—broad mound, finer foliage, early flowers—to a local nursery or Extension service. Check the replacement varieties' growing conditions and mature sizes.

Hostas die back in winter, and Japanese painted fern is deciduous too. Adding more of either won't give you winter screening. Keep an existing suitable evergreen behind the border, or let a well-shaped path and bed edge give the winter view its structure. Choose any new evergreen for the space and local conditions, not just to fill a winter photo.^{2Source 2HostaNC State Extension,4Source 4Japanese painted fernNC State Extension}

Deer and slugs can damage hosta foliage. Companion planting doesn't make the hostas deer-proof. If browsing is already severe, settle on workable protection or choose different focal plants before expanding the bed. Hostas are also toxic to dogs, cats and horses if eaten; choose other plants where animals are likely to chew them.^{1Source 1HostasUniversity of Minnesota Extension,3Source 3Hosta 'Blue Mouse Ears'NC State Extension}

Once you know what can stay, photograph the whole border with the path visible. Gardenful can help you picture a fuller planting idea around the hostas you want to keep, with suggested plants and quantities to explore. Compare the idea with your measured space before choosing what to buy.
