  4. Pollen Free Multi-Petaled Oriental Roselily 6 pc.

    This brand new collection of Pollen Free, multi-petaled Oriental Roselilies is one of the foremost lilies to have been created in many years and can be found practically nowhere else in the United States. The unique collective term “Roselily” has recently been coined in reference to these exceptional Oriental lilies for a few reasons. As these extraordinarily beautiful flowers open with their multiple layers of petals, they resemble both an Oriental Lily and a Rose. Furthermore, these lilies do not exhibit the strong fragrance associated with most oriental lilies, but rather a delightful mild fragrance and neither do they contain the obnoxious pollen that has ruined so many of our clothes.

  8. 3 Year Old Reblooming Daylily Collection 3 pc

    There’s an old adage in the garden world referring to perennials’ growth that goes something like, “Watch ‘em sleep, creep, then leap!” What this means is that the first year your perennials will sleep, spending most of their energy growing roots underground as opposed to above-earth growth. Year two is when they creep, and slowly start to show slight exuberance in the garden. But then the magic happens in the third year when they leap and grow leaps and bounds! So, if you could, wouldn’t you rather fast track your plants and go directly to the leap stage? Us too. That’s why Roberta’s 3 pc. Three Year Old Reblooming Daylily Collection is so spectacular.
