18-24 inches.it gets leggy with shade.It looked horrible last year being shaded by taller plants(cannas.castor bean,goldenrod)I have one spot thats giving it total full sun non stop& the other(pictured)is afternoon shade.I'm glad this year the stems are growing
stright not curly and bent this way and that way or plum flat to ground.It also reseeded a lil in last years spot(3 lone stems)
another favorite is the profusion ones.I like the orange better than the white seemed to bloom more.I liked the persion carpet too,but the stems seemd very dainty.It reseeded as well.My liliput's reseeded and we're the 1st to bloom.I have 2 pinks in bloom right now.I have some california(cut& come again...you cut...it branches and blooms again....over& over)I saved them by color,but only kept the orange& the pink with orange overtones and salomon.I saved some white....but won't know WHICH white till bloom.I lost the green envy& even with cleaning computer room have not came across.I know they are in glass jar...just not WHERE.I'd love to try the 2 toned ones or even just some plain yellow. I tried the carnival/state fair ones,they don't like my climate.They got brown spots on the whole plant ( but liked the reds coloring)I tried some dwarfs long time ago was bought as plant& it really bloomed alot!

or better.My other 2 patches are smaller.I have these sown in my patriotic section in hex bed.hopeing to seed
