Mrs. Spud,
I having been buying from "dutchbulbs.com" for the last two years and have been very satisfied. The selecton is pretty good and more importantly there
plants are garanteed. This year I had purchased ten potentilla cinquefoil
plants and nothing came up. When I dug them up they were rotted! Bummer. But they are sending me replacement
plants within the next week. I now realize I should have added some sand or perlite to the soil mix. Luckily, they are willing to accomodate my novice experience.
The other thing I would suggest if you go with a company that garantees the
plants, definitely save your invoices!!! I bought eighty lilies of the valley and only 62 survived. Again, glad they will replace the lost ones.
The downside is it is not quite as satifying as perusing a great nursery and getting instant
plants.
Good luck though
