About Blue Mouse Ears Hosta

Hosta 'Blue Mouse Ears' · also called Blue Mouse Ears hosta, miniature blue hosta · flowering

Hosta 'Blue Mouse Ears' is a popular award-winning miniature hosta forming a tight mound of thick, rounded blue-grey leaves shaped like little mouse ears. In summer it sends up short scapes of lavender bell flowers. Slug-resistant for a hosta and ideal for shady containers, edging and troughs, it was an American Hosta Growers Hosta of the Year.

Plant type: flowering

Watch for — Loss of blue colour: The blue is a waxy bloom that wears off in heat, sun and overhead watering. Grow in cooler shade and water at the base to preserve it.

The reasons blue mouse ears hosta isn't blooming

Almost every non-blooming blue mouse ears hosta traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding blue mouse ears hosta a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get blue mouse ears hosta to flower

Maximise sun. Give blue mouse ears hosta the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for blue mouse ears hosta and get the feeding right with the blue mouse ears hosta fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Blue Mouse Ears Hosta flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.
