Verbena canadensis (Glandularia canadensis) - ROSE VERVEIN

Drought, heat and humidity tolerant wildflower, flowering at the end of spring and beginning of summer.

Lilac-purple flowers, usually reblooms in late summer. In ideal conditions does bloom nonstop.

Somewhat ground covering/trailing growth. Basal part stays evergreen.

Blooming time : late April/May (usually starts after the creeping phloxes) till June, sporadic blooming trough the summer and usually rebloom in late summer. In richer soil usually blooms the whole season
Size: up to 1' tall x 1-2' wide
USDA Zones: 5 to 8 (for zone 5 we recommend decent drainage)
Culture: full sun, partial sun, partial shade - ideal is 6+ hours of direct sun or more. Average soils, heavier, but drier soils, drier clay, rocky, sandy, gritty soils with average moisture to dry. Prefers some drainage (soil amended with some sand or fine gravel, but can handle clay, if it is dry clay). Avoid wet and waterlogged soils. Tolerant to heat and humidity, established plants tolerate droughts
Moisture Needs: average (medium) to dry
Origin: we obtained seeds from Missouri Wildflowers Nursery, raised a few seedlings that we planted in our garden ad started to propagate. Some cross pollination with Verbena 'Anna's Pink' (northern Indiana genotype, hardy to zone 5) possibly happened. Natural area of this very showy wildflower is wide, reaching from deep south to north, also from central USA to the east coast - that's why the hardiness differs so much and plants from southern areas act like true annuals, while the "northerners" are perennials. See the USDA distribution map.
Deer/Rabbit Resistant: the whole plant is aromatic = yes / yes
Attracts Butterflies or Pollinators: yes/yes This plant doesn't look to be "pollinator magnet", but we spotted some pollinators (bumblebees, hummingbird moth, random bees) and occasional buterfly
Attracts Hummingbirds: possibly yes
Pot Size: square 3.5" x 4" deep perennial pot

Plant Combinations: For sunny garden (public and private), can be planted in small groups or as individual plant in smaller beds. For the front, edges, along patios and paths, bigger rock gardens, slopes and bigger containers. Best combined with smaller to medium sized perennials or groundcovers. Good companions can be Agastache, shorter Amsonia, Antennaria, Asclepias tuberosa, shorter Aster, smaller Baptisia, Campanula rotundifolia, Coreopsis, Cunila origanoides, Dalea, Eryngium juccifolium, Echinacea, Gaillardia, Gaura, shorter Liatris, Penstemons, Ruellia humilis, Stokesia, Yucca, native grasses like Boutelloa gracilis or B. curtipendula, Eragrostis, Koeleria cristata, Schizachyrium, Sporobolus heterolepis 'Tara' (or non-native Sesleria), Stipa, medium-sized Panicum.

And non-native perennials like Achillea, summer blooming Allium, Armeria,  Calamintha, Campanula, Cerastium, Delosperma, Dianthus, Eryngium, Geranium (G. sanquineum, G. dalmaticum and x cantabrigiense, G. endresii, G. renardii), Gypsohila, Iris x barbata (=I. x germanica), Lavandula, Nepeta, Origanum, Paeonia, Perovskia, Platycodon, Satureja, Salvia, Sedum, Sempervivum, Stachys, Scabiosa columbaria, Thymus, lower Veronica,...
