Hello Cindy. On the matter of space i have a residential 60ft. x 120ft. corner lot. Front of my house faces east where i have 6 cultivars planted. In back i have a big L shaped bed where a good half of maybe 140 plants are. Against the back of the house getting morning sun are 15 more cultivars.
I also have 2 smaller beds one by a gate and another backed up against privacy fence. One holds 2 plants plus other perennials. The other holds about 15 more.
On the south side facing the street i easily have 20 more cultivars. On the SE corner i have anew bed with only 3 different cultivar but they are lined out for mass planting because i have several of each in there.
Finally i cannot plant on the north side of the house because of a hill that slopes down to the house next door. The cul de sac slopes down and we have the high ground and we get more than our share of the wind too.
Next spring the big L in back will get bigger i just have to work out the details. The house next door is for sale but 2 mortgages would break our budget.
