Plant of the Month

Artichoke Agave, Parry Agave
Agave parryi

  • Plant Form: Succulent
  • Water Use: Very Low
  • Mature Size: 2-3 ft. tall & wide
  • Exposure: Full Sun
  • Bloom Time: Summer (June-Aug)
  • Native to: Arizona, New Mexico, Texas, Mexico
  • Hardiness: Cold hardy to 15°F 

Artichoke Agave forms a dense, symmetrical rosette that actually resembles a giant artichoke. Wide, foot-long, blue-gray leaves are edged with spiny margins and tipped with a one-inch terminal spine. A rosette slowly matures over time until it produces offset “pups” at its base, eventually forming a colony of rosettes. Each rosette flowers only once, usually after 10-15 years, but sometimes not until 20-30 years. From the center of the rosette, one giant flowering stalk rises up to 20 feet tall, after which the flowering rosette dies, but all the new rosettes formed by suckers around the base of the mother plant survive. The flowering stalk is eye-catching, with clusters of orange-yellow flowers on many side branches.This popular ornamental agave is used as an accent or specimen, in borders, or in mass plantings. It is great in succulent and rock gardens, and in containers.

Part of my appreciation of our native desert plants comes from the indispensable gifts that these plants have provided for millennia to humans, wildlife, birds, insects, soils, and the whole ecosystem. Indigenous peoples have long valued and used native desert plants for food, medicine, healing, shelter, clothing, utensils, and ceremony.

I would like to share some of these uses that we can incorporate into our lives today, but this comes with a responsibility to reciprocate thoughtful care and stewardship for these tenacious but fragile desert dwellers. I always encourage respectful harvesting and mindful use of our native plants (join one of our workshops to find out how! We prepare these native plants for you to taste, drink, smell, touch, and experience). I also strongly encourage the purchase and planting of native plants in our own yards, especially if we want to harvest their gifts regularly (see our section, Native Plant Nurseries, for southwest nurseries that sell California native plants). By incorporating plants into our yards that are native to our own region, we also help sustain native butterflies, native bees, birds, wildlife, and migration corridors for all of them, as well as reducing our dependence on added water, fertilizers, and pesticides in our yards. Growing plants that thrive in our climate also reduces our time and cost to maintain our yard). It is truly a win-win scenario.

Now is the season to enjoy sautéed flowers and young seed pods of Bladderpod, Peritoma arborea. All parts should be cooked before eating to eliminate the potentially irritating compound glucocapparin (ill-smelling, but it repels insects and herbivores like rabbits from eating the plant). Not everyone is sensitive to this compound, but if you are eating quite a bit of the flowers, flower buds, or seed pods, it is prudent to cook them to render the compound harmless. The flowers and seed pods are simply delicious when sautéed in olive oil with a shake of salt and pepper. The young, green seed pods have a flavor like a very mild jalapeño pepper. Native American Indians today, relying on native traditions, say that they boil the flowers for several hours (discarding the water several times) before sautéing them to remove any bitterness. We have found them delicious after simply sautéing the fresh flowers — so experiment for yourself!

Bladderpod is in the caper family; you can make your own wild capers by harvesting the unopened flower buds and pickling them (they are longer and slimmer than the commercial, round capers that you are familiar with, but they have a fascinating flavor similar to the capers you are accustomed to eating). Put the unopened flower buds in a jar and cover them with water. Secure the lid and let them sit at room temperature for 24 hours. Every day for three days, drain off the water in a colander or strainer, return the “future capers” to the jar, and cover them with fresh water.

Then soak them in a brine of equal parts apple cider vinegar and water, with 1 tablespoon of salt per cup of liquid, for at least one week (a month is best). Alternatively, you can soak the flower buds in equal parts seasoned vinegar and water for a delicious caper.

Bladderpod can be encouraged to flower continuously for many months with occasional deep watering. It is also fire-retardant and extremely drought-tolerant, which makes it a perfect choice for your yard. Hummingbirds, hawk moths (that hover like hummingbirds at dusk before the flowers), quail, and other birds are attracted to this “giving” plant. We encourage you to invite this valuable native plant into your own yard. Both you and your birds and pollinators can benefit from its presence (and “presents”).

Bladderpod plant parts traditionally used:

  • Seed pods – Young seed pods roasted or sautéed to eat
  • Flowers – Young flowers parboiled, roasted, or sautéed to eat
  • Flower buds – Unopened flower buds pickled to use as wild capers


 June Garden Tasks

An easy way to move cactus during planting is to use micro-tube hose for smaller plants or a section of old garden hose for larger cacti.

An easy way to lift and move cactus during planting is to use micro-tubing for smaller plants or a section of old garden hose for larger cacti. You can also move larger cacti by laying plants over on an old rug or carpet and pulling into place.

Good season to plant or transplant palms or cacti


~ Prune fast-growing trees like mesquite, palo verde, and acacias to reduce chances of wind damage. Don’t remove more than 20 percent of a plant’s foliage at any one time to avoid stress or sunburn of trunk and branches.

~ Keep adding to mulches throughout the summer to conserve water, keep roots cool, and deter weeds. Water well before applying the mulch (or through an opening in the mulch), or you’ll insulate dry soil rather than moist soil.

~ Water your plants deeply enough to thoroughly soak the soil, but infrequently enough that the soil dries out between waterings. This encourages roots to grow deeper into cooler soil for better drought tolerance.

~ Continue to deadhead spent flowers for a longer bloom cycle.
