  1. Gloriosa Climbing Lilies Collection 4 pc.

    Filling your garden with some of the richest beauty it can handle, Roberta’s 4 piece Gloriosa Climbing Lilies Collection will have you singing praises and giving glory. As a semi-tropical climbing vine, their exquisite, luxuriantly colored blooms resemble flowers made of flames, and it is aptly known also as the Fire Lily. It will undoubtedly be the brightest flower in your garden. Our Gloriosa Climbing Lilies are perfectly suited for the ground in the warmer regions of the country, or in a container next to something to climb on such as a fence, pole, post, mailbox, banister on your porch, a tree, or even another shrub. If you live in a colder region but prefer growing them in the ground, simply lift them at the end of the season, like you would a dahlia. Their courageous tendrils at the edges of their foliage allow them to grow up just about any surface, unlike most other climbing vines. So if you are looking to create a wall of color, these Climbing Gloriosa Lilies are your first step. Or for an even more dramatic entry into your garden, grow them near another shrub and they will actually climb them and produce the illusion of growing out of another plant. Imagine your viburnum or arborvitae producing bright red flowers all summer long! What other vine can do that?

Their fringed flowers are composed of ruffled white petals with an inner disc featuring rings of blue, white and purple and topped off with a vibrant crown.
