Discovered in 2016 here at Plant World, this astrantia has the largest and most impressive flower heads we have ever seen! The name 'Supernova' is inspired by the huge maroon, dome shaped flower heads, surrounded by green-tipped bracts, that look almost like a red sun ready to explode. Also boasting a compact and dense habit, we believe this one will be a prize winner in years to come! Unfortunately we have been able to collect just a few fertile seeds which we are willing to spare, and these are absolutely exclusive to our website. This one really is first-come-first-served!
Sowing advice: For best results, sow seeds immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. However, we sow most seeds in an unheated greenhouse and wait for natural germination as many seeds have built-in dormancy mechanisms, and often wait for spring before emerging regardless of when they are sown. But spring sowing will obviously give them a full season of growth if successful germination occurs.
