18-24" x 22-28" wide. Agave utahensis ssp. kaibabensis is an uncommon form of the Utah Century plant and is the largest growing subspecies of this group. It is found on the high Kaibab Plateau around the Grand Canyon in northern and western Arizona. The long, stout, narrow leaves are olive green in color and the plant eventually blooms with very tall flower spikes up to 15 or more ft. tall. These slow growing plants are quite cold hardy where winters are dry. In bloom, the flowering stalks can reach to nearly 20 ft. in height!
Tips for Growing Cacti and Succulents
Cacti shipped early in the spring may be dormant. As the weather warms, these cacti will expand and green-up. Remember, after an initial watering to settle the soil around the roots, no further water should be applied until the weather warms up. If plants are dormant and the spring weather is rainy, protect the plants from too much moisture by covering them with a gallon plastic milk container with the bottom cut out. Leave the top off the jug so heat build up isn’t excessive in sunny weather.
All the species of hardy cacti and succulents require fast-draining soil.
Planting in the ground
Put the plants on a slope or raised area of the garden, not in a low spot which collects water. Select a bed with full sun exposure, preferably next to a south or west facing wall. These areas will provide extra winter warmth. In heavy clay soils, it is essential to replace half or more of the soil from a 10”x 10” or larger hole with coarse sand and gravel mixed thoroughly with the remaining soil to ensure adequate drainage. No compost should be added, only a small handful of Planters II and Yum Yum Mix®.
Planting in an outdoor pot or planter
Use a planting mix of 3 parts garden soil + 2 parts coarse sand + 2 parts coarse perlite (or similar material). When growing plants indoors in pots, use a good quality potting
soil to mix with the sand, and expanded shale instead of garden soil.
1. Cacti, agaves, and tap-rooted succulents (Aloinopsis, Titanopsis, Nananthus) should be transplanted bare-root. Let the soil in the pot dry out for a few days. Then remove the pot and gently loosen the soil so it falls away from the roots. Trim off any broken roots. Bare root plants should then be planted into a shallow hole. Spread out the roots evenly and sprinkle the soil into the hole until full. The base of the plant should rest on top of the soil. Mulch with a 1⁄2”-1” thick layer of pea-sized gravel around the base of the plant to protect it from contact with soggy soil over the winter months. (See planting diagram on page 12 of our Planting Guide.)
2. Succulents with fibrous roots (Ruschia, Delosperma, Sedum, and others) need not be transplanted bare-root, instead, the root ball should be scored and roughed out like
1. Bare-root cacti and tap-rooted succulents must not be watered right away, but should sit dry for a day or two to allow the roots to callus over any broken or damaged
areas. Other succulents can be watered in right away. Water thoroughly with a mixture of SeaCom-PGR and Superthrive to stimulate strong new root growth. Water again with this mixture two weeks later.
2. Outdoor beds with new plants should be initially watered once every 5 to 7 days for the first month or so after transplanting. Cacti and succulents enjoy regular watering
during the heat of the summer and will grow vigorously. After the first year, most cacti species need a good soaking only once every 2-4 weeks during the spring and summer if there has been no rain.
3. Potted plants require more frequent, regular watering, especially if the weather is hot and dry.
4. To prepare cacti and succulents for the approach of winter, begin withholding water in the fall so the plants can begin to dehydrate and shrivel. Plump, well watered plants are ripe for cold damage when temperatures plunge in late fall/early winter.
Cacti and succulents are very modest in their fertilizer requirements. When planted in the ground, fertilizing in spring with SeaCom-PGR and Yum Yum Mix® will encourage plentiful flowers and good stem growth. When planted in pots, remember to feed monthly with the same mixture as above, beginning in late summer.
Garden plants: Many cacti and succulents are quite cold hardy if kept dry in the cold winter and spring months. In areas that receive a lot of winter and spring moisture
(especially rain), it is strongly recommended that plants be protected from cold, wet soil conditions. For example, a temporary cold frame can be constructed using pipe or
PVC hoops covered with a clear plastic sheet to cover the entire bed. Or individual plants can be covered with plastic gallon milk jugs with the bottom cut out to keep
the ground around the plants dry. Leave the top off the jug so heat build up isn’t excessive in sunny weather. Problems will occur if plants are in wet soil all winter or
sit under melting snow for extended periods.
Potted plants: Should be moved under a roof overhang on the south or west side of the house or placed in a well ventilated cold frame. Water pots and other containers lightly a few times over the winter during warm spells.
All our cacti, agaves and succulents are seed-grown or cutting-grown in our greenhouses. Cacti and agave plants are 2-4 years old; succulents are 1-2 years old. Please, never collect cacti from the wild unless it’s to rescue plants from construction sites. Many species are close to extinction in their native habitats due to irresponsible collectors.

Grows where an agave shouldn't.
By Travis Snyder
from Salt Lake City
About Me Avid Gardener
Comments about High Country Gardens Agave utahensis ssp. kaibabensis:
I have this agave planted in Salt Lake City, in northern Sugarhouse, 9th&9th neighborhood.it's located in a place where several other plants failed, and now knowing what agave prefer, well drained dry locations, I wouldn't have planted an agave in the location I planted this one.It is in the lowest area of my yard. it's still well drained, but it compacted and less well drained than the rest of my yard. The dirt is a silty loam.The area gets lots of snow, and next to a side public walk, driveway, and rock stairs, and not far from the street so it gets exposed to some snow melting salt in the winter.in the summer, this area is the most exposed area to sun, and gets the least amount of water. it's baked by the sun, and by its concrete and stone environment. it gets no sun in the winter, and up to 6-7 hours direct sun in the summer. it's planted in a small valley and never gets more than 6-7 hours of direct sun. It gets mostly dappled sun which sounds like the worst place for an agave. If you are in a tough place for agave and want one, this is the one you want.
Bottom Line Yes, I would recommend this to a friend

These are strong healthy little plants
from Hutchinson, Ks.
Last year I ordered 2 Agave plants, 1 Agave parryi Parry's Century Plant, Flagstaff form and 1 Agave havardiana Havard's Century Plant. Our winter here in zone 6b Kansas got down to 10 below zero on two nights, it usually only gets down to minus 5 but both plants are tough as nails with no protection, it didn't even faze them. My Agave parryi 'J.C. Raulston that I bought from another nursery bit the dust so I am ordering this Agave utahensis ssp. kaibabensis to replace it. Another commentor said they are a small plant, well they are advertised that they come in a 2.5 inch pot so of course they are small. But for the price they are a great bargain.

Disapointed that it is a small plant and is currently hanging on.
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
