Bred by Ozbreed, it is one of the longest flowering dianellas, sending up masses of baby blue flowers to about 55cm, and it takes drought and cold once established. In the southern states it is a mass planting workhorse; north of Sydney it is a plant for a well drained, cared for garden bed.\u003c\/p\u003e\n\n\u003ch2\u003eWhy you'll love it\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRich blue foliage.\u003c\/strong\u003e The leaf colour is a true blue grey rather than green, which lifts a native bed and pairs with silver and burgundy foliage.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne of the longest flowering dianellas.\u003c\/strong\u003e Baby blue flowers on fine stems come in flushes through spring and summer, with purple berries after them.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact and clumping.\u003c\/strong\u003e It stays at 50cm and does not run, so it holds its line along a path or in a drift.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrought and cold tolerant.\u003c\/strong\u003e Listed for Tasmania and the ACT as well as the mainland states, it handles frost and dry summers once established.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eYears between prunes.\u003c\/strong\u003e A cut back by half every three to five years is the only maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhere it works best\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eMass planting in the south.\u003c\/strong\u003e Plant 40cm apart in offset rows, which gives about six plants per square metre, and the clumps meet within two seasons to form a dense blue carpet.
