Van Remsen Salvia, Anise Sage

Salvia 'Van Remsen' (S. guaranitica hybrid)

Large intense deep blue flowers emerge from tall spikes beginning in spring and continuing throughout the growing season and into fall. Van Remsen Salvia, an Anise Sage or chance hybrid, is an excellent nectar plant for hummingbirds and may also be visited by larger butterflies. Unlike many of the Salvia guaranitica selections available Van Remsen is a clump forming vigorous growing perennial that can hit 7' high bringing the flowers closer to the hummingbirds and towering over most other garden perennials. This cultivar was discovered in the garden of James Van Remsen of Louisiana and was named and introduced by Salvia guru Richard Dufresne of North Carolina. Provide a full to mostly sunny location in an average moist, well-drained soil for optimum vigor and flowering. Item# 12118

Variegated Blue Sky Vine, Blue Trumpet Vine

Thunbergia grandiflora 'Variegata'

Large creamy yellow, white, and green foliage acts as the backdrop for large hanging clusters of 3" wide, sky blue trumpet shaped flowers that are produced on new growth throughout the summer and into fall. The Variegated Blue Sky Vine is a vigorous twining tropical vine that revels in the warmth of summer and this form appears to be just as vigorous and sun loving as the solid green form. Evergreen in frost free locations, establish in spring once the danger of frost has past as a die-back perennial vine in zones 8-9, or it can easily be maintained as a container plant where not hardy.

A crown of deep sapphire blue filaments create a striking contrast with the white petals and sepals that are held against the rich green foliage throughout the growing season. The Blue Crown Passionflower is a vigorous growing tropical vine and can easily reach 20' once well-established. This is also one of the most reliably cold hardy Passionvines with foliage remaining evergreen in the mildest 8B winters but dying back to the ground in severe winters and returning readily in spring. The Blue Crown Passionflower may spread somewhat by rhizomes but it is generally much more tame than the Maypop. Cross pollination may produce tropical tasting tangy fruit that surrounds the dark seeds inside.
