Gardeners' Notes:


On Jul 1, 2013, coriaceous from ROSLINDALE, MA wrote:

The tallest Veronica I know, and the longest blooming. The flower color ranges in hue by cultivar from white to true blue through violet and purple to clear pink, and may be pastel or deeply saturated. The bloom season extends from the end of June into September if spent spikes are promptly removed---prompt deadheading induces a full second round of bloom. It makes a great long-lasting cut flower.

It's self-supporting in full sun but may need support in partial shade.

Emerges from dormancy exceptionally early in spring, neck and neck with Aconitum. Has evergreen basal foliage.

Plants need consistent moisture and full sun for best performance. This is less drought tolerant than your average border perennial.

If you love blue flowers, this is definitely one for your garden. I put it in front of a cypress vine and behind coreopsis 'Early Sunrise', for a very vivid color spot.

I planted what the tag calls Veronica and Creeping Veronica. The Veronica turned out like Daves picture of speedwell and the creeping veronica turned out the same only real dark purple. Which is fine and prefered. But as far as "creeping'? don't know yet. They both seem to be thriving well. One in a sheltered corner and the darker out in a full sun flowerbed. The darker gets watered everyday with the underground sprinklers and the lighter gets water when ever it deems nessessary. I hope they fill in as that is the main reason I purchased them. After countless plantings of anything you could think of, this is the only plant that seems to have lasted all season and looks like it will come back next year. I am going to mix tall shasta daisy s with them this fall and hopefully create a beauti... read more

Long-leaf Speedwell is a tall compact clumping perennial of upright habit. Moderately quick-growing & long-lived, it prefers ferile, moist but well-drained soil. The foliage has a fine texture, and the late summer blooms are blue, sometimes pink. This plant is native to Northern Asia and Central Europe but has naturalized to parts of the U.S. and Canada.
