Poa sieberiana

Snow grass, Grey Tussock-grass, Small Blue Tussock-grass

Family: Poaceae

Poa sieberiana is a dense tussock grass with green to greyish green leaves which grow to about 50 cm long. There is also a blue variety var. cyanophylla.

Leaves are fine to very fine, 0.2–0.7 mm wide, straight or curved to flexuous, usually scabrous.

It has very attractive inflorescences (panicles) which rise well above the foliage, to about 1 metre tall, from spring through to summer with pale green to purple seed heads.

It is drought and frost tolerant, fast growing and very hardy and long lived.

It will grow in full sun or part shade in most soil conditions.

In the garden

Poa sieberiana is an attractive feature plant, ornamental grass ideal for landscaping and suitable as edging or border plant for beds or paths.

In the home garden the author pruned to remove spent seed heads (usually late winter) as this encouraged fresh new growth and found they looked their best if planted in clumps of odd numbers.

It has been and continues to be very popular in large native garden landscapes.


Division of tussock or from the numerous seedlings if conditions are right. Ripe seed can also be used.
