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.

Don's Dwarf Wax Myrtle, a selection of Myrica cerifera, a.k.a Morella cerifera, makes a tough and easy, low-maintenance low to medium-sized evergreen hedge that could easily be used to replace Boxwood, Indian Hawthorn, and even Dwarf Yaupon Holly in the garden and landscape.

Provide a full sun to part shade site in a fertile, average to well-drained soil for optimum growth and vigor. The only drawback is that Wax Myrtle is subsceptible to fire and so should be utilized away from houses, businesses, and other structures, although, the plants themselves generally recover from the root stock. Item# 12746
