USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
36-40" tall x 18-24" wide. Eryngium planum ‘Blue Glitter’ (Sea Holly) is an outstanding Old World perennial that blooms in summer with tall stems of spiny, glistening blue flowers. A European bred plant for the cut flower trade (fresh and dried), it is a profuse bloomer that is invaluable for attracting bees and butterflies. It thrives in less than ideal garden conditions.

Eryngium (Sea Holly) is a genus of Old World perennials with attractive thistle-like flower bracts surrounding the round flowers. Highly attractive to honeybees and butterflies. Preferred growing conditions:
Plant in a fast-draining, infertile soil with full sun. Avoid clay soils. Mulch with gravel or not at all.
Water regularly the first growing season to establish the plant. Thereafter, infrequent but deep watering is all this plant needs.
Deadheading is not needed as it will not extend the bloom season or bring the plants back into flower.
Fertilize lightly in the fall with a half and half blend of Yum Yum Mix and good quality compost.
Special comments:
Eryngium is a tap rooted plant and does not like to be transplanted once established. Don't divide as tap rooted plants resent having their roots disturbed.
Seed heads are ornamental and attract seed-eating songbirds.
These are low care perennials that don't like rich soil or a lot of water; this makes the plants leggy and prone to flopping.
