New Millennium Stars Mix Delphinium
Delphinium This hybrid series mix of first-year-flowering delphiniums features some of the most glorious cultivars I’ve seen—Black Eyed Angels, Blue Lace, Cobalt Dreams, Lilac Ladies, Moonlight Blues, Pagan Purples and Pink Punch, to name a few.
Elegant cylindrical terminal flower spikes rise 3-6' above waist-high clumps of palmate glossy green foliage. The New Millenniums develop thicker sturdier flower stalks than the more widely known Pacific Giants. Considered more tolerant to heat and humidity than many standard cultivars, yet the New Millenniums also thrive in super-chilly corners of the world with reports of successful perennial plantings in frosty parts of Canada and even Alaska!
Avoid overhead watering to prevent disease. Mulch recommended to keep the roots cool and moist. Delphiniums are hungry hippos—sidedress regularly with compost for best bloom. Plant 32-36" apart in highly fertile non-acid loam. Light shade is best but full sun is fine. 60" tall. Z3. (3½" hardy plug stock)

Herbaceous Perennial Plants
When you receive your order, open the bags and check the stock. Roots and crowns should be firm and pliable. If they are slightly dry, add a little water or, if they are going to be potted up soon, wet the roots. Generally, a little surface mold is harmless and will not affect the plant’s future performance. If you cannot pot them up immediately, store them in a cool (35–40°) location for a short time.
Do not plant bare-root perennial plant crowns directly outdoors.
Pot up the rootstock using well-drained potting mix in a deep 6" pot or a 1-gallon container. Avoid coiling the roots in under-sized containers.
Grow newly potted perennials for a few weeks in a protected location in indirect light at 50–60°. Wet and/or cold conditions for an extended period may cause rotting.
Transplant outside once they show some top growth and the danger of frost has passed.
