How to grow Xanthisma
When growing Xanthisma species such as Texas star from seed sow outdoors just after the last frost of spring. Texas star seeds should be lightly covered once sown and spaced from 15cm (smaller Xanthisma) to 60 cm (larger Xanthisma varieties0 apart. Ideally Xanthisma will grow in a sunny part of the garden that as good drainage. The soil that Xanthisma plants grow in should be sandy, close to neutral pH and light for best results, but they should grow in most soils.
If starting off indoors then sow seeds about seven weeks before the last frost. It should take Xanthisma three to four weeks to germinate at a temperature of 20 to 23 degrees centigrade. Transplant into the garden following the last frost.
