You need to split your data.frame:

p1+geom_table_npc(data=summ,label =split(summ,summ$variable),
npcx = 0.00, npcy = 1, hjust = 0, vjust = 1,size=2)

or nest the summary table you have:

summ <- summ %>% nest(data=-c(variable))

# A tibble: 4 x 2
  variable               data
          >
1 Sepal.Length        [1 × 9]
2 Sepal.Width         [1 × 9]
3 Petal.Length        [1 × 9]
4 Petal.Width         [1 × 9]

p1+geom_table_npc(data = summ,label =summ$data,
,npcx = 0.00, npcy = 1, hjust = 0, vjust = 1)
