Have prepared plates last night with this Gentiana - remains to see which one it is after the capsules form.
Grown from seeds as Gentiana vernayi (AGS seedex) - an annual species, little species!!! The seedling was planted in the rock beds of forumist Robert Pavlis; we were curious to see what it will be; obviously it needs to be moved out of there.
Gentiana dendrologi and robusta are very similar; Gentiana tibetica can also be confused but the stamens in this case are inserted at middle part of corolla.
Please check up your plants before donating seeds, especially for Gentianas from Cruciata section.
