This summer, two of our spiking clumps of Agave ovatifolia became dislodged from the ground during a violent thunderstorm. We wondered if they would still set viable seed despite being without roots, since the energy built up from 15 years of growth was still in the foliage. We made several crosses without having to set up a ladder and it appears that we’ve got good seed set. Nature is amazingly in its desire to survive.
Agave x striphantha ‘Striptease’ is a JLBG creation from a 2013 cross of Agave striata and Agave lophantha. Both parents are 30 year survivors here in the garden, so we wanted to see what a combination of genes looked like. Also, Agave striata is the only hardy agave species, whose main crown doesn’t die after flowering. So far, this gem is 3′ wide, and like the Agave striata parent, it offsets from the crown and doesn’t sucker like Agave lophantha. It’s looking like a flower spike may be imminent, so perhaps we’ll have our flowering question answered soon.
One of our most unique agave seedlings is a selection of Agave lophantha in which the tips of the leaves turn bright gold during the cold winter months. Here is our parent clump that’s been in the ground since 2011. Hopefully just a few more years and we’ll have enough to share…assuming there is any interest.
When creating hybrids, especially with plants like agaves, it takes many years to know exactly what the offspring will look like. We have a pretty good guess, since we’ve done this for so long, but here’s an updated photo of a cross we made in 2013 of Agave striata x Agave lophantha. The hybrid, that we call Agave x striphantha is now 3′ wide, which is the same width of the Agave striata parent. We expected the hybrid to stay a bit smaller, but it did not. What we still don’t know is what will happen when it flowers. Agave striata is the only hardy species that doesn’t die after flowering, while the flowering rosette of the other parent, Agave lophantha cashes it in after its sexual encounter. Hopefully, it won’t be long before we know about the hybrid, and hopefully it will produce viable seed.

There are many agave that are hardy in our Zone 7b garden that many people would not think would live here. The key to successfully growing agaves is proper siting, planting, and culture. These are pictures taken this week of agaves in the garden.
