Eryngium agavafolium

Evergreen Eryngium that we love.  The glossy deep green strappy leaves are fiercely armed and form large rosettes. In summer 28″ spikes produce bright green clover like orbicular flowers on a divided scape. You won’t draw rattlesnakes but you will draw bees. Cool looking plant that is easy to grow in rich to average well drained soil Good appearance even during winter. Remove the flower scape when the blooms start to turn brown- not as pretty. Sexy plant that requires no summer water and just full sun. Long lived. I see boulders and Cacti and grasses and gravel. Sexy rosettes.

Eryngium bourgotii

Very blue, oh so blue shorter Sea Holly that has pretty unusual leaves as well as stunning flowers. Crinkly sage green leaves are prickly and outlined in fine white. From this batch of foliage the flowering spike attains about 20″ inches before producing the metallic sky blue star shaped flowers. Very pretty and it will instantly draw pollinators. Remains in bloom for 4-6 weeks from early to mid summer. Full sun, rich, well drained soil and little summer water when established. Tough but pretty perennial that is very long lived. Increases in width each year to 2′ wide. Excellent candidate for the hellstrip, the front of the border or gravel gardens. High deer resistance. Completely deciduous in winter.

Eryngium pandanifolium

Kind of hard to believe this is a sea holly but this enormous evergreen perennial from Argentina definitely is. Long upright soft green spikes leaves emirate from a large rosette to about 3′ tall by 3′ wide. In summer 6′ tall spikes support off white orbicular flowers on tall divided scares. Pollinator heaven. A very dry climate appearance lends it to pair with cactus, Nolinas, even Agaves. Gravel gardens large dry borders. Full sun and very little water once established. Protect from subfreezing wind if an arctic event threatens. High deer resistance. Big bold plant.

Eryngium pandanifolium var. lesseauxii’

Fun tall growing sea holly that may be impossible to pronounce but its easy to grow. Upright growing finely serrated or prickly leaves first make a low 2′ wide rosette then when it feels like it- usually the second year a big as spike rises with a divided scape and tons of off white prickly clover like flowers dot the stem tips. Its cool. This whole perennial is cool and its slightly hardier than the species. Very cool. Evergreen perennial for full sun and just about any well drained soil. Flowers rise to 5′ tall and with time there will be many spikes. Pollinators arrive in droves to pollinate this very unusual but architectural perennial from South America. High deer resistance.

Eryngium planum ‘Blue Hobbit’

A dwarf Sea Holly- such a good idea in a genus of mostly towering space eating plants. Spoon shaped green leaves form a basal rosette. Then in summer flowering stems rise to only 18″ and produce multiple deep blue flowers. They are vibrant but a little spikey. Adored by pollinators. Especially bumble bees (why are those big bumbles so drawn to blue flowers? I need to know.) Full sun and average to rich well drained soil. Perfect tor the front of a border or a gravel bed or anywhere you want a blue Eryngium without scraping airplanes. Drought tolerant cold hardy perennial that is long lived.

Eryngium x tripartitum

Easy to grow, though short lived (2-3 years) this prolific seeder will never really disappear from your garden. A hybrid by two UNKNOWN species one from South America and the other one is anyones guess. First year its a rosette of spoon shaped green leaves. The following year it dramatically rises to 3′ in spring/summer and produces clouds of rounded steel blue flowers. Very pretty and airy and you must mix it with a nice tall ornamental grass for the ultimate effect. As I mentioned it then seeds around. Interesting cut flower.  Drought tolerant and best in full sun. High deer resistance.

Eryngium yuccafolium

Rattlesnake MASTER! Great common name for a wonderful perennial that fits the modern aesthetic perfectly. Low rosettes of silvery serrated pointed leaves are subtle. In summer 30″ branched spikes produce rounded clover-like white balls- these are the flowers and they remain showy for weeks and weeks before finally turning brown in late summer- that the time to remove them. This robust member of the carrot family is sure draw for pollinators and even works well as a huge architectural cut flowers ( the flowers up close kind of smell bad- never smell an Eryngium you’ll regret it) but the fragrance is only detectable up close. Amazing with ornamental grasses. A flower with great presence that makes everybody else look better. Photographs well. Full sun to very light shade in any well drained site. Light to little summer water. Completely winter deciduous. High deer resistance. Rosettes increase with time and so do blooms spikes. Long lived.

Eryngium giganteum

Miss Wilmotts Ghost. As the legend goes Miss Wilmott would stealthily drop the seeds of this biennial into the gardens of those she visited. Sneaky girl. The plant would germinate and produce a low inconspicuous rosette of leaves the next year. The following year a tower of ghostly gray collared huge flowers on branched stems would appear- seemingly form nowhere. Freak. But my kind of freak. A really cool looking plant in bloom that photographs amazingly well by the way. To 3′ tall for full sun and open disturbed sites. It will reseed reliably in those conditions. The seedlings are easy to spot  and move when they are very young if you desire a new spot.  Makes a groovy large cut flower. This is the flower on our logo. High deer resistance. Drought adapted.
