Growing Blue Hostas

Blue Hostas Sienna Hosta


Of all the many colours of hostas there are available today the blues remain a staple of every big collection. Eye popping waxy blue leaves always stand out in the garden, complimenting others around them whilst adding interest themselves. Growing blue hostas to the fullest of their capabilities is no always as straight forward as popping them in the ground and letting it do their thing.

Positioning is key when planting blue varieties as light levels and temperature can drastically change the quality and longevity of their colour. A cool, shady spot under a tree canopy is ideal. Blue hostas get their colour from the wax (bloom) on their leaves, this can be removed by heavy rain, bright sunlight and high temperatures which is why planting under a tree canopy will help the colour remain.

Blues come in all shapes and sizes from some of the larges varieties like 'Blue Angel' and 'Blue Mammoth' to some of the smallest like 'Blue Mouse Ears' and 'Bill Dress's Blue'. Here are some of our favourites.
