Caesia parviflora

Caesia parviflora is known as blue grass lily. It is a perennial in the Asphodelaceae family. It is native to the east and southeast of Australia. Kew lists it as a plant of subtropical climates. It grows in a range of open habitats. The account gives a height of 1 foot [0.3 metres]. It gives no mature spread and does not describe the leaves.

The roots are a little fleshy. Plants For A Future lists them as edible. It gives them a low food-use rating, based on scant details. It does not say how to prepare them or how much to eat. It lists no known hazards, but this does not prove safety. There is no specific evidence here on risks to pets. The source lists no known uses as medicine. It lists no other known practical uses either.

The flowers have both male and female organs. The evidence gives no flower colour, shape, or bloom season. It gives no details on fruit or pollinators either. These gaps limit what we can say about seasonal interest. Plants For A Future suggests beds and sunny woodland edges. Its low height helps guide the choice of planting spot. The source does not report pest or disease problems.

Plants For A Future says this species needs light, not shade. It lists sand, loam, and clay as suitable soils. The soil should drain well but hold some moisture. The listed pH range runs from slightly acid to slightly alkaline. Its growing notes suggest sun and shelter from winter weather. Reports from Australian gardens record survival down to 19°F [−7°C]. This does not prove it can withstand British garden winters. Cooler summers may change the outcome, as may longer, wetter winters. The source does not settle how hardy it is in Britain.

Plants For A Future lists seed and division as ways to grow more plants. Its seed advice is tentative. It does not draw on detailed trials of this species. It suggests sowing fresh seed in a warm greenhouse. It suggests spring sowing for stored seed. Young plants would stay in their seed pot through year one. The method then calls for one more year under glass. Planting out would follow in early summer. The database does not flag this species as weedy.
