It is very difficult to find an Osiria rose bush to purchase, although they are sometimes available through spaldingbulb.co.uk or eBay.com. A better option is to purchase seeds to plant and grow. You can purchase seeds through AliExpress.com and through some sellers on Etsy.com.
While very beautiful, with red petals on the inside and white petals on the outside, gardeners do not consider the Osiria rose to be a healthy plant. Each bush has few flowers that can be slow to re-blossom. When gardeners post photos online, they often retouch them to make them appear more dramatic than they do in real life. This can be disappointing to those who attempt to add this variety to their gardens. This has led many plant sellers to discontinue selling the Osiria rose.
