The provided constraints have some redundancies (e.g., the minimum water need is specified twice).  We've consolidated these in the code below.  The objective function is to minimize the total cost, calculated as 6.23 * (number of cherry trees) + 4.36 * (number of sunflowers).

```python
from gurobipy import Model, GRB

# Create a new model
m = Model("PlantOptimization")

# Create variables
cherry_trees = m.addVar(vtype=GRB.INTEGER, name="cherry_trees")
sunflowers = m.addVar(vtype=GRB.INTEGER, name="sunflowers")

# Set objective function
m.setObjective(6.23 * cherry_trees + 4.36 * sunflowers, GRB.MINIMIZE)

# Add constraints
m.addConstr(19 * cherry_trees + 9 * sunflowers >= 88, "min_water_need")  # Combined minimum water need
m.addConstr(19 * cherry_trees + 9 * sunflowers <= 221, "max_water_need") # Combined maximum water need
m.addConstr(18 * cherry_trees + 30 * sunflowers >= 59, "min_planting_space") # Combined minimum planting space
m.addConstr(18 * cherry_trees + 30 * sunflowers <= 62, "max_planting_space") # Combined maximum planting space
m.addConstr(8 * cherry_trees + 32 * sunflowers >= 24, "min_beauty_rating") # Combined minimum beauty rating
m.addConstr(8 * cherry_trees + 32 * sunflowers <= 39, "max_beauty_rating") # Combined maximum beauty rating
m.addConstr(5 * cherry_trees + 27 * sunflowers >= 98, "min_growth_speed") # Combined minimum growth speed
m.addConstr(5 * cherry_trees + 27 * sunflowers <= 289, "max_growth_speed") # Combined maximum growth speed
m.addConstr(25 * cherry_trees + 1 * sunflowers >= 32, "min_yield") # Combined minimum yield
m.addConstr(25 * cherry_trees + 1 * sunflowers <= 161, "max_yield") # Combined maximum yield
m.addConstr(7 * cherry_trees - 3 * sunflowers >= 0, "cherry_sunflower_ratio")


# Optimize model
m.optimize()

# Print results
if m.status == GRB.OPTIMAL:
    print('Obj: %g' % m.objVal)
    print('Cherry Trees: %g' % cherry_trees.x)
    print('Sunflowers: %g' % sunflowers.x)
elif m.status == GRB.INFEASIBLE:
    print('The model is infeasible.')
else:
    print('Optimization ended with status %d' % m.status)

```
