Vancouveria hexandra  AMERICAN BARRENWORT  A native relative of the Epimediums sharing the same family Berberidaceae.  Vancouveria is one of those plants that no natural woodland garden should be without, that being said it is a hard plant to procure and is not readily available in the trade in great quantities like a Rudbeckia or a Coreopsis, which probably adds to its charm.  The flowers color is white and their size is small but numerous being up to 45 individual flowers on one inflorescence.  They prefer bright shade.  One of our gardening friends had Vancouveria planted in the shade of an old tree where it languished and never really got going.  The tree was damaged in a storm and had to be removed, which increased the amount of light to that area of the garden and prompted her little Vancouveria to spread and flower, as it never had before.

Verbascum When one thinks of Verbascum or Mullein, the intrepid species V. thapsus comes to mind.  Often seen growing in rocky outcrops and other seemingly inhospitable areas along the highway. Many garden worthy species and hybrids are available to the gardener, some are perennial while others are best considered annual or biennial.  All plants flower along racemes or spikes, which rise from rosettes of often-hairy leaves.  Flower color is variable ranging from whites and yellows to red.  Plants tolerate varied soil conditions but all generally prefer full sun in lean soils.  V. chaixii is a short lived perennial.  V. bombyciferum is a biennial.  Many Verbascum hybrids should be considered a short lived perennial due to the biennial nature of their parents.

Verbena bonariensis VERVAIN A tall upright perennial growing to 5 feet. Clusters of small, ¼ inch, purple flowers form in summer on top of open wiry stems.  Although plants are only hardy to zone 7, by allowing some flowers to set seed you can enjoy this Verbena the following season in zone 6.  Most of the plant height is attributed to the flowering stems, which has a wispy open habit creating a see through effect.

Vernonia IRON WEED These native perennials are popular for late season color. The tall yet sturdy plants make a fine backdrop in a garden.

Veronica spicata 'Red Fox', V. spicata 'Goodness Grows' SPEEDWELL Both are low, long blooming plants with glossy dark green leaves of medium size. They prefer moderately fertile, well drained soil demanding average moisture only. The taller V.

They associate well with other plants and are easy to grow, with neat and colorful flower spikes. Veronica p.

Veronicastrum virginicum CULVER'S ROOT, BLACKROOT Prefers wet conditions and needs full sun to maintain its tall and sturdy upright habit. Branching stems hold many dark green leaves, which grow out like the spokes of a wheel. In late summer branches end in white flower spikes that are neatly and firmly upright occasionally attaining a pale pink tint. The vertical and horizontal structure and durable heights of this plant make it valuable for design. Native to woodlands and meadows of our Northeast.
