The reddish, branched stems measure three to six millimeters in diameter. Cilia cover the internodes.
The lanceolate leaves are longer than those of iresine herbstii 'Purple Lady The dark leaf blades - ranging in color from wine-red to raspberry - arecriss-crossed with carmine-red veins.
In summer, when growing conditions are optimal, small creamy-white flowers enhance the foliage.
Fruits, membranous capsules, are even rarer when grown indoors. They contain the seeds that enable the plant to multiply.
Iresine herbstii 'Acuminata' is non-toxic. You can grow it without putting young children or pets at risk.
Our maintenance tips
There's a simple trick to finding out if your Iresine herbstii 'Acuminata' is thirsty. Look at its foliage. If the plant sags and looks limp, it needs water. Once watered, it will regain its upright habit.
Watering
Wait until the surface of the soil has dried by two or three centimetres before watering again.
Pour in water at room temperature. The substrate should be moist but not soggy. Drain any water that collects in the cup or planter.
Spray
Spraying foliage with non-calcareous water (e.g. Mineral water or rainwater) helps to maintain humidity levels.
Repotting
Every spring, repot your Iresine herbstii 'Acuminata' to give it more space.
Obtain a pierced pot with a slightly larger diameter than the previous one (two centimetres larger, for example). You can line the bottom with a bed of clay balls to optimize drainage.
Iresine herbstii 'Acuminata need a rich, aerated substrate. Mix perlite (approx. 10%) with potting soil for green plants. Pour in a layer of soil.
Plant your Iresine herbstii 'Acuminata' in the center of the pot. Add potting soil and tamp lightly. Water with room-temperature water to encourage rooting and remove air bubbles.
Fertilization
To promote the growth of your Iresine herbstii 'Acuminata', apply fertilizer in spring and summer.
Apply a special green plant fertilizer every three weeks to stimulate foliage growth.
Prune
Pruning before wintering helps the plant regenerate.
Do a winter pruning to force the plant into dormancy. Shorten stems with clean, sharp pruning shears. Remove about half the year's growth.
Pinch
Pinch your Iresine herbstii 'Acuminata' during its growing season.
Use your fingers to pinch the tips of the branches. This forces the plant to create new branches and helps maintain a compact habit.
Plantation
When the risk of frost has passed, it's time to plant.
Place your Iresine herbstii 'Acuminata' in part shade or full sun. Make sure, however, that the plant does not face due south. The midday sun could burn its foliage.
Dig a hole slightly larger than the root ball. Put some compost in the bottom. Plant your plant. Mix your garden soil with the heather soil and use this mixture to fill the hole.
Make a layer of organic mulch at least five centimetres thick. It will help keep the soil cool and reduce watering during the summer.
Cutting
Cutting is carried out during the strong growth phase, generally in spring and early summer.
Using your pre-cleaned scissors, remove a ten- to fifteen-centimeter stem (about three nodes). Remove the leaf at the base of your cutting.
Pour potting soil into a bucket. Plant your cutting in the center.
Cover with a transparent bag or place in a mini greenhouse. Propagation works best under cover. Set up in a bright room with a temperature of at least 20°.
Mist the substrate to keep it moist, and aerate for a few minutes a day.
