Galium odoratum SWEET WOODRUFF The leaf is characterized with rich green whorls that provide good foliage all season. The plant should be grown in a cool, moist soil. Ground cover for edging borders and paths, or used as an underplanting for naturalized and woodland settings. It's gentle sweet fragrance and snow-topped appearance when in bloom would shurely be missed in any shady garden without it.

Gentiana septemfida var. lagodechiana Gentians in general prefer the cooler climate of zone 5 and colder.  G. septemifida is slightly more tolerant of warmer temperatures and together with proper cultural practices will survive.  Flowers in summer are blue and bell shaped and face upwards above low domes of green leafy stems.  This species is adaptable but needs a lot of sun in well-drained soils.  Waterlogged winter soils will quickly kill the plant.
