Shrub Forsythia × intermedia 'Karl Sax' [Karl Sax Border Forsythia] The Karl Sax Border Forsythia is a dense shrub that bears its dark yellow flowers horizontally. Flower buds are more cold hardy than many Forsythia variants, but flower buds can be killed by severe winters in zone 5, and frequently in colder zones. Plants, however, are hardy in Zone 4. Cut stems excised in mid-winter will flower indoors due to very short chilling requirement. Too big for most foundations and small border plantings (Don't Shear!).…

Tree Indiana Native Fraxinus americana [White Ash] Not as adaptable as Green Ash but has better esthetics. Heavy crops of seeds on female trees cause litter, and these germinate freely making the tree slightly weedy. An unattractive ash flower gall (caused by mites) can develop on male flowers and persist into winter. Subject to storm damage, so plant in areas that shelter the tree from strong winds. Emerald Ash Borer is severely affecting all species of this genus. Damage can be prevented…
