Guess what some of the most popular hostas are? The blue ones — and the bigger they are, the more gardeners love them. Blue hostas come in a variety of sizes, from dainty miniatures, like Hosta ‘Blue Mouse Ears,’ to medium Hosta ‘Big Daddy,’ to giant Hosta ‘Blue Angel’. It’s easy to see why blue hostas are popular. Blue is an elusive hue in the garden, and one most gardeners crave. Blue hostas deliver shades of blue — steel blue, silvery blue and blue green — in a carefree plant.

Hosta ‘Blue Angel’ is one of the classic blue hostas that leans toward a larger-than-life size. Plants eventually form mounds that measure up to 6 feet across with leaves standing atop stems to 3 feet tall. The blue-green leaves complement white flowers that appear in summer. Use ‘Blue Angel’ hosta in a traditional shade garden, or include it in a shady foundation planting bed.

Hosta ‘Big Daddy’ is another classic blue hosta that puts on some size in the garden. Plants grow 12 to 24 inches tall and spread 24 to 36 inches across. Thick leaves boast strong slug resistance, along with a richly textured surface. The blue color remains strongest when ‘Big Daddy’ hosta is in shady conditions, although the blue fades to green as summer wears on.

On the other end of the size spectrum is the deep blue miniature ‘Blue Mouse Ears.’ This dainty plant makes an eye-catching edging along shady beds and also adapts well to container growing. ‘Blue Mouse Ears’ hosta forms a tidy mound that’s 8 inches high by 12 inches wide. The leaves are thick and almost rubbery, which makes this a strong slug-resistant hosta. Lavender flowers appear in midsummer.

Other popular blue hostas include Hosta ‘Blue Cadet,’ Hosta ‘Bressingham Blue’ and Hosta ‘Fragrant Blue.’ ‘Blue Cadet’ hosta is a medium size hosta, growing 15 inches tall by nearly 3 feet wide. It’s a go-to hosta for using as a border plant, either incorporated into a planting area or edging it. Plants open lavender flowers in midsummer. ‘Blue Cadet’ hosta leaves tend to fade to green in midsummer, even in cooler northern regions.

Another giant blue hosta is Hosta ‘Bressingham Blue,’ which creates a mound that’s 28 inches tall by 68 inches wide. It unfurls thick leaves with a corrugated texture. Those characteristics give it slug resistance. The blue color on this hosta can fade with sun exposure, so it’s best to site it in deep shade. Plants open white blooms in early summer.

For a strong blue color that doesn’t fade, plant Hosta ‘Fragrant Blue.’ This hosta produces new leaves all summer long, so the blue tones are deep and constant. Plants have a medium size, forming a mound 20 inches high and 4 feet across. Pale lavender flowers appear in late summer. Despite the name, the blossoms are barely fragrant.
