Agave havardiana

Agave havardiana
First-year plant
hardy century plant; Big Bend century plant
Second-year plant
Common name hardy century plant; Big Bend century plant
Family agavaceae
Life cycle perennial (Z6b-10)
Flowers yellow-green (summer)
Size 24-36"
Light sun
Cultural notes needs excellent drainage; drought-resistant

Forms a neat mound of spikey blue-gray leaves. Flowers occur only after decades of growth, so I'll forget about those. Should be just about hardy around here, as long as I can keep winter wet from killing it. I've tried growing hardy agaves before, but never got them through more than one season. Hopefully better luck this time, with seed-grown plants. My current attempt has them living in hypertufa troughs, which I plan to bring into the garage over winter. The seedling in the picture at left (photo taken in August) lives next door to an even smaller saguaro cactus.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
