Glaucium grandiflorum x flavum hybrids


Add to wishlist Remove from wishlist
Horned Poppy. Officially designated as a Xeric Awesome Perennial, these originally came to us as seeds from Panayoti Kelaidis' home garden in Denver. This has rosettes of foliage which erupt in early summer to 2'-3' branched displays of orange to yellow poppy flowers. Nifty long curved seed pods too. This really wants good drainage in lean soil with hot sun where it will self sow which is good as the parent plants can be short lived. We had one make a low wide dome of gray-green foliage and we counted between 400-500 orange-yellow flowers on it - hopefully some of these seedlings will carry on the tradition. Some of these will be Glaucium flavum, some will be grandiflroum and others will be obvious hybrids but none will disappoint.
