Gardeners' Notes:

Positive anelson On Sep 19, 2014, anelson from Birchwood, WI (Zone 3b) wrote:

This hosta is a very good grower - providing plants to divide. It is an attractive neat more-green-than-blue plant, and has nice deep lavender blooms.

Seattle WA -- I have grown Blue Cadet in 1 or 2gal containers for a number of years -- they are spectacular grouped together on my back patio. 2010-2011 Winter was especially cold for Seattle, but these hosta survived with no damage at all -- in the containers too.

These Blue Cadets are slug resistant ... but best to put down slug bait when crowns are budding and leaves just emerge. After leaves are at full size for the season, no further slug bait is needed.

Grows slowly and takes N. Texas heat in the shade.

A nice, compact, blue hosta. Blooms June-July in my garden.

This little soldier of a hosta is a cutie. Give him a little time, though, as he has not been a fast grower, at least for me. He has multiplied at a steady rate, but not taken off like a shot as many of the smaller hosta do.

Positive ifonly On May 26, 2006, ifonly from Brookfield, CT wrote:

This is a terrific blue hosta. It forms a tight mound of heart-shaped leaves, retains its blue color in my CT garden, and blooms its head off. Scapes are not too tall, and simply covered in blooms. Love the picture of Blue Cadet next to what looks to me like Francis Williams - I sense a move coming.

Positive darylmitchell On Jun 10, 2005, darylmitchell from Saskatoon, SK (Zone 3a) wrote:

Blue Cadet is a very nice small hosta. Mine is in constant shade of a northern exposure and still performs well. It forms a mound of blue-green foliage 12-18 inches wide. The lavender flowers emerge in mid-summer. It prefers moist soil.

Neutral smiln32 On Apr 16, 2004, smiln32 from Oklahoma City, OK (Zone 7a) wrote:

This little hosta grows very quickly and isn't picky about where it's put in the shade garden. It makes a thick mound in a season (two at the most) and is also easily divided.

Neutral louisenh On Apr 1, 2003, louisenh wrote:

Multiplies very quickly, blue retained all summer (in med shade at least), nice understory hosta for larger hostas, usually available cheap in bare-root boxes of 3-6 at discount retail outlets. Tough as nails. Just not the most interesting hosta.
