Growing tasRed dianella

Light. The South Australian Plant Selector+ gives part shade to full shade. A grower's information sheet gives full sun to heavy shade, but says that in Sydney it suits only shaded positions, while in a climate like the Blue Mountains it can take full sun.

Soil and water. The Plant Selector+ ticks clay, loam and sand, acid to alkaline, and minimal supplementary watering.

Climate. The Plant Selector+ ticks drought and moderate frost, and the grower's sheet calls it drought tolerant and cold hardy. No reference read gives a frost figure in degrees.

Care. The Plant Selector+ says to avoid trimming it in drought or in the middle of summer. The grower's sheet calls it relatively pest free.

Colour. The grower's sheet says the red at the base shows in colder climates, and that the foliage changes from green to green with red tinges at certain times of the year.

Using tasRed dianella

For shade: the Plant Selector+ gives understorey planting, shaded borders and verges massed, or a single plant as an accent beside other strap-leaved kinds. The grower's sheet calls it dense and tidy, and says it has excellent erosion control capabilities. No reference read gives a planting distance.

It sits below the straight species in size: the Plant Selector+ gives TasRed 0.3 to 0.4 m high and wide, against 0.6 to 2 m high and 0.5 to 2 m across for Dianella tasmanica, and the grower's sheet gives 45 cm high and 50 cm wide.

What to check before you buy

TasRed is protected under the Plant Breeders Rights Act 1994: the grower's sheet says it may not be propagated without authority and is available only to licensed growers. It is listed as TasRed, usually with the code TR20 beside it. The grower's sheet notes it is produced from tissue culture and finished in 140 mm pots. The table above shows the sizes growers list. The Plant Selector+ entry for TasRed says Dianella tasmanica is now Dianella prunina; VicFlora still accepts Dianella tasmanica, so labels may carry either name. What to look for before stock leaves the grower is in the guide to nursery plant quality.
