Birder, the grow thru stakes is what most growers use. I have that on my list of things to get. Most poppies are fine until they get blasted by the rain. The shorter ones do ok. I believe Jo Ann uses these. She will have a better insight once she spot this thread. Mike
I usually try to remember to use large hoops on oriental poppies, in order to keep them more upright. I actually find them to be quite a pain in the butt sometimes - they take up a huge radius when in active growth and bloom, and then go dormant, leaving large gaps in the flower beds. Using the hoops will minimize the size of the gaps left, as it allows the surrounding plants to grow unimpeded (that might otherwise be shaded out or dominated by the oriental poppy foliage). Well, I guess the flowers are worth it, as I've put up with this for so many years already!! (On the other hand, oriental poppies are also almost impossible to get rid of... every little bit of root left will regenerate, and the roots go down to China too. Lucky the flowers are big and showy!)
I am with altagardener. and Hazelcrest is right.I do use supports. I made a mistake and used the grid type.The hoops are much better.
I support because I planted too close to the border and the mower interferes with the leaves.
A full Oriental poppy can reach 36 inches in diameter.
