Too late to plant summer blooming bulbs?
My wife ordered a summer blooming bulbs variety pack, which contains Caladiums, Calla Lilies, Dahlias, Elephant Ears and Gladiolus. The pack arrived 2 days ago. Given that tomorrow (June 21st) is the first official day of summer we are wondering, is it too late to plant these bulds? We are in Colorado, zone 5.
If it is too late, can these bulbs be stored for next year?
Thanks in advance ... :-)
