Selected Plants of the

National Capital Cactus & Succulent Society

2010 Show and Sale



Echeveria 'Black Prince'


Echeveria 'Black Prince'

Grown and Exhibited by:  Ingrid Fritze

This plant was judge Best in Show for the "other" succulent Division.  It's  an exceedingly beautiful and well grown plant.  



Haworthia truncata v. maughanii

Haworthia truncata var. maughanii

Grown and Exhibited by:  Bob Petza

This plant won the Blue Ribbon in Class 19c (Haworthias) and is a great example of how wonderful plants in this genus can be.  This is one of the truncated haworthias and is always a great hit with the visitors to the show.




Tephrocactus molunensis

Tephrocactus molinensis

Grown and Exhibited by:   Bob Petza

There were several attractive opuntias in this year's show, but far and away the public seemed drawn to two plants, and this was one of them.   This was the Blue Ribbon winner in the Opuntia Class 6.  T. molinensis is native to Argentina where is grows in very sandy soils with the stems partially buried.  It has no spines but does have large clusters of reddish glochids, which thankfully, are not easily detached.

The tephrocacti are members of the subfamily Opuntioideae and certainly have the look of an opuntia.  They also have those nasty glochids.   Glochids are very small spines that  occur in clumps  on the body of opuntias and look like tufts of hair.  They are however, not tufts of hairs but exceedingly annoying tiny spines that irritate and itch when they get into your skin. 
Lithops lesliei

Lithops lesliei  var. venteri

Grown and Exhibited by:   Bob Stewart

Unfortunately, this was the only lithops entered in the specimen plant division of the show.  However, Bob also entered an education display on lithops and there were a number of additional lithops plants as part of the display.   Bob grew this plant from seed planted in 1999.  It represents the form of venteri from Cole lithops colony C153.   Lithops are native to South Africa and Namibia, and members of the Aizoaceae plant family.

Melocactus azureus


Melocactus azureus

Grown and Exhibited by Bob Stewart

The Blue Ribbon Winner in Class 7 and another great seed grown plant by Bob Stewart.  Bob sowed the seed in 1993 and the cephalium developed in 2006.  (The cephalium is the strange looking thing on the very top of the plant.  It's made up of many fine bristles and once it forms the main body of the cactus stops growing and from then on only the cephalium increases in size.)   M. azureus is native to Bahia, Brazil. 
Dudleya hassei


Dudleya  hassei

Grown and Exhibited by Ty Tydings

The Blue Ribbon Winner in the Echeveria/Dudleya Class.  We don't see many dudleyas in our shows and this is an especially nice one grown by Ty.  D. hassei is native to the island of Santa Cataline off the California coast.   Dudleyas are members of the Crassulaceae family.
Astrophytum 'Super Kabuto'

Astrophytum  'Super Kabuto'

Grown and Exhibited by Ingrid Fritze

These cultivars/hybrids of Astrophytum asterias are one of the most popular cacti today and Ingrid has been raising a number of them from seed.  Ingrid reports that only approximately 25% of the seedlings develop the heavy, white flocking that makes this plant so desirable.   Ingrid, who produces many blue ribbon plants for our shows, grows most of her plants in a small backyard greenhouse. 
Mammillaria microthele

Mammillaria  microthele

 Grown and Exhibited by Bob Stewart

The Blue Ribbon plant in the mammillaria class was this interesting specimen of Mammillaria microthele.    In Ted Anderson's book, The Cactus Family, this plant is listed as Mammillaria formosa subsp. microthele. and native to the Mexican States of Queretaro and Guanajuato.   Many show visitors commented on the interesting manner in which this plant was staged, giving the plant an "in habitat" appearance. 
Agave victoria-reginae

Agave victoria-reginae

Grown and Exhibited by Ingrid Fritze

First Place in the Agave Class went to this beautiful specimen of Agave victoria-reginae.  This was another great combination of a large, well grown plant and the perfect container.   The plant was clean and symmetical, without blemish, and the container was clean, attractive, and just the right size.   A. victoria-reginae is native to Mexico.  It's not hard to grow, given a sunny location, a well drained potting soil, and regular watering, but does  grow slowly.
Ariocarpus trigonus



Ariocarpus  trigonus

Grown and Exhibited by Bob Stewart

First Place in the Ariocarpus Class was this well grow 7 inch diameter Ariocarpus trigonus.   While plants in the genus ariocarpus are very slow growing, and rather touchy in terms of soil moisture, A. trigonus is perhaps the largest, fastest and easiest to grow species in the genus.   In recent years the botanist have tended to list A. trigonus as a variety under A. retusus.  Because of general familiarity of it as a distinct species, and perhaps because he didn't want to have to make another label, Bob entered his plant as Ariocarpus trigonus.  This is another Mexican native and can grow up to 10 inches in diameter over time.  As with the other ariocarpi, it flowers in late summer/early fall and the flowers are yellow.
