Temperature Requirements
The plant Asystasia axillaria Lindau ex Engl. can grow at temperatures between 18°C and 29°C. However, it prefers warmer temperatures, so it will grow best at around 25°C.
Soil Requirements
The plant Asystasia axillaria Lindau ex Engl. prefers well-draining, slightly acidic soil with a pH between 5.5 and 6.5. It can grow in both sandy and loamy soils, as long as the soil is well-drained.

Cultivation
Asystasia axillaria Lindau ex Engl., also known as Blue Wave, is a perennial herb that can grow up to 70cm tall and spread up to 1m wide. It prefers well-drained soil and partial shade, making it an excellent choice for garden beds and borders.
The plant can be propagated from stem cuttings or seeds. If growing from seeds, it's best to sow them in spring/early summer and keep them moist until they germinate. For stem cuttings, it's best to take them from healthy plants during the growing season, dip the cut ends in rooting hormone, and place them in a well-draining potting mix.
Watering Needs
Asystasia axillaria Lindau ex Engl. prefers consistently moist soil but doesn't tolerate waterlogged conditions. Water the plant regularly, keeping the soil evenly moist, especially during hot and dry spells. However, avoid overwatering, which can cause root rot and make the plant susceptible to diseases.
Fertilization
Blue Wave benefits from regular fertilization during the growing season to maintain its lush foliage and promote healthy growth. Apply a slow-release fertilizer every four to six weeks, or use a liquid fertilizer every two weeks. Be careful not to over-fertilize, as this can result in weak growth and root rot.
Pruning
Pruning is not necessary for Blue Wave, but periodic trimming can help the plant bush out and produce more flowers. Pinch off the tips of the stems regularly to encourage branching and maintain the desired shape. Remove any dead, damaged, or diseased foliage as soon as you notice it to keep the plant healthy.
Propagation of Asystasia axillaria Lindau ex Engl.
Asystasia axillaria Lindau ex Engl. can be propagated through seeds, cuttings, or division.
Propagation through Seeds
The plant produces small, black, shiny seeds that can be collected and sown in a well-draining soil mix. They should be lightly covered and kept moist until they germinate, which usually takes around 2-3 weeks. The young seedlings can be transplanted into larger pots as they grow.
Propagation through Cuttings
The plant can also be propagated through stem cuttings. Take stem cuttings that are around 10cm long and remove the lower leaves. Dip the end of the cutting in a rooting hormone and plant it in a well-draining soil mix. Place the pot in indirect light and keep the soil moist. The cutting should root and start growing in a few weeks.
Propagation through Division
Asystasia axillaria Lindau ex Engl. can also be propagated through division. This method involves separating the plant into smaller sections and replanting them. Carefully dig up the plant and separate the roots into smaller sections. Each section should have a few stems and a healthy root system. Replant the sections in individual pots or in a garden bed.
