Understanding Plant Options
Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age
- Bare Root Plants: Dormant plants without soil, sized by height measurements
Container Plant Sizes

#ProPlantTips for Care:
Sea Holly does best in full sun and sharply drained soils. Eryngium does not like to be overwatered. Preferring rich, fertile soils, but tolerant in more demanding, less than optimal settings, Sea Holly adapts to almost any setting that has well-drained soils. Even thriving in poor soils. Just be sure to water regularly when first planted, to ensure it gets established. Even thriving in poor soils. Just be sure to water regularly when first planted, to ensure it gets established.
