About soil condition, Hebe rakaiensis is an endemic species that is found only on the Rakai Plateau in central Otago, New Zealand. It is a member of the mint family and is a short-lived herbaceous perennial. The soil is well-drained and relatively infertile. Hebe rakaiensis is pollinated by bees and flies.
So, like the other plants, the Hebe rakaiensis needs sun light to grow. The plant grows best in partial to full sun, but can also tolerate partial shade. If the plant does not get enough sun, it will become leggy and its leaves will turn yellow.
The temperature condition of the Hebe rakaiensis plant is that it prefers warm weather and can withstand frosts down to -5ºC. It can also tolerate salt and wind, making it an ideal plant for coastal areas.
Ideal humidity condition for this plant is 50% and above, however it can still survive in lower humidity conditions as long as the air is not too dry. If the air is too dry, the leaves will start to turn brown and curl up.
Discussing fertilizer, this family of plant is not too needy, and actually does quite well in average to poor soils. They also have a moderate to high tolerance for salt. However, they do require good drainage, as the roots will rot in waterlogged soils. When planting, make sure the root ball is not sitting in water. Also, take care not to break any roots when transplanting.
Pruning is an important part of keeping your hebe rakaiensis plant healthy and looking its best. Regular pruning encourages new growth, which keeps the plant looking full and lush. It also helps to remove any dead or dying leaves and stems, which can help to prevent disease.
Propagation : Hebe rakaiensis is best propagated from semi-ripe cuttings taken in summer. Remove a well-developed shoot from the plant and cut it into 3-4 inch cuttings. Place the cuttings in a well-drained potting mix and water them well. Keep the pot in a warm, sunny location. The cuttings should root within 4-6 weeks. Once they have rooted, transplant them into individual pots and water them regularly.
Usually, the plant growth rate studies have been conducted in New Zealand, where the species is endemic. In general, Hebes tend to have slower growth rates than other plant species. A study published in 2009 found that the average growth rate of hebe rakaiensis was 0.47 cm per month.
Common problems for this kind of plant are powdery mildew, rust, and leaf spot. These can all be controlled with fungicides. If you see any of these problems on your plant, be sure to treat them right away.
