Eryngium Coronatum

Hooker's eryngo does best with abundant light, reflecting its native habitat where light is plentiful. Less light can reduce its growth and vibrancy. It can tolerate suboptimal light conditions, but growth will be slower. Prolonged periods of insufficient light can cause damage.

Hooker's eryngo can tolerate a wide range of temperatures, though its distribution may still be restricted by different combinations of moisture and heat. It performs best in warm summer climates with adequate rainfall or irrigation. Long stretches of cloudy, rainy weather or prolonged high temperatures increase the chance that Hooker's eryngo will die. In winter, protecting it properly from cold improves its survival rate.

When most of Hooker's eryngo's blooms have reached full size, resume fertilizing. Around the time blooms are at peak production, apply fertilizer every three to four weeks, as weather permits. After the plant begins producing fewer new blooms, stop fertilizing; there is no need to feed it when it can no longer produce additional blooms.
