Q: Can blue hibiscus be grown successfully in Lahore — I haven’t seen them here. There are two most common species with blue flowers Alyogyne huegelli and Hibiscus syriacus. Can these be grown in Lahore from seed and do they require the same care as wild hibiscus?
A: I suspect that you mean Hibiscus huegelli not Alyogyne. H. huegelli, the Australian satin hibiscus with gorgeous lavender coloured flowers and Hibiscus syriacus should both be fine as long as good growing conditions are provided. They are very different in their requirements to wild hibiscus. Give them well drained, sandy soil with lots of humus worked in and grow in full sun. Take care that the seedlings do not damp off.
