Giant White Hyssop

Agastache

Lovers of heat, these tough and drought-resistant Mint family relatives guarantee terminal spikes adorned with brightly colored, tubular flowers just about all summer long. Agastaches are easily grown in well-drained soil, and will bloom more profusely, over an even longer period of time, if the flowering stems are cut back midseason.

A luminous white-flowering form of the Korean species, this superb cultivar has been vegetatively propagated to assure its garden-worthy status. Purple-tinged bright green leaves plus upright steady stalks promote a slew of generous, 6 in. tall, bottlebrush-like spikes with long-blooming pearly flowers and green calyces. Valued by bees, moths, hummingbirds and chefs, ‘Alabaster’ survives wet winters, demands good drainage and favors yearly pruning, while brightening perennial borders and herb gardens as well as nectaries.

Blooms July–October

Size: 2' 0" – 3' 0" high x 18" – 2' 0" wide.

Zone 5/6.

Our feature plant: Primula vulgaris ssp. sibthorpii

Precious Primulas, Prized Pulmonarias and Fabulous Foliage!

Primulas offer elaborately-crafted colorful blooms in varied shapes,……

including draped bells, candelabras, drumsticks and pincushions. Many Primrose flowers  waft a delectable scent. Second-to-none for the dappled recesses of your garden, these easily grown, cold-hardy Primulas crave well-drained, humus-rich niches with adequate moisture and good air circulation. They can grace containers or be planted in swaths along shady walkways or in woodland gardens. Be sure to peruse our online Primulas.

Prized Pulmonarias……

One of the earliest perennials to bloom, you can be picking their enchanting urn-shaped flowers in February while the rest of the garden still slumbers. Many cultivars showcase an array of mercury-hued dapples, speckles and spots, while others sport solid pewter sheens or striking silver streaks. Easy-to-grow Pulmonarias prefer the lacy light of a woodland setting plus cool moist soil. Our newsletter also includes a handful of other shade-loving perennials that promise alluring foliage. Many of these perennials can be partnered with Pulmonarias for intriguing foliar contrast. You may wish to check out our online Pulmonaria offerings.

All of us plant and paper wranglers wish you good health and happy digging!
