Gardeners' Notes:

Positive coriaceous On Jan 25, 2014, coriaceous from ROSLINDALE, MA wrote:

Easy, tough, vigorous clump former. The blue-green foliage is elegantly twisted like a cowlick and does not go dormant in summer. Much hardier than indicated above, to z3-4. The species in China gets 18-24" tall, but the plant that goes about under this name in North American gardens does not get much taller than 8". It does not grow thickly enough to smother weeds.

Positive sanannie On Dec 2, 2006, sanannie from White Lake, ON (Zone 4b) wrote:

Attractive, blue-green, twisted foliage that grows in a small circular clump. Pretty pink umbels in late summer. Very easy to divide and a group of them make a nice edging to a small bed. I'm a fan of this little cutie.

My information says that this is hardy in zones 3-9.

This is a fun little plant with great foliage for an allium.
It does tolerate just about any soil or light condition, but seems to do best protected from afternoon sun.
In our Z5 location, it is a slow spreader. In three years we have not had to divide or thin it out yet.

I have grown "curly" or "twisted" chives (var. glaucum) in zone 3 of north-central Minnesota for 4 years. It is perfectly hardy here, although not a rampant spreader.

I have a version called "circle chives" that grows itself round into a circle. Tough, takes drought, stands division but leave in place if you want to see the full circle! Take from the edges when your friends want some. Like all alliums, flowers attract pollenators that sting; do not plant too close to steps or walkways.

Neutral smiln32 On Aug 31, 2001, smiln32 from Oklahoma City, OK (Zone 7a) wrote:

Easily grown in average, dry to medium wet, well-drained soil in full sun to part shade. Best in full sun, but appreciates some light afternoon shade in hot summer climates. Tolerates a wide range of soils. Drought tolerant. Although this allium is a true bulb on a rhizome, plants form dense clumps which are easily divided in either spring or autumn. Clumps will slowly spread and self-seeding often occurs. Deadhead flowers before seed sets to help control any unwanted spread.
