3" pots Cactus need bright sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 70% to 80% mineral grit such as coarse sand, pumice, or perlite. Water deeply and wait for the soil to completely dry out before watering again..

It can take a bit more frequent water than most cacti, but it does need full sun and excellent drainage to thrive. Unlike most Opuntia, this variety will not tolerate extended frost.
Mexican Lime
A large barrel cactus that sports funky, pink spines. This species has 13-20 ribs lined with red to pink spines. In the wild, mature plants can reach up to 10.0' tall and 20.0" in diameter. When grown in hot, sunny conditions, the Lime Cactus can bloom in late winter to spring with vibrant red-orange flowers. These flowers develop into juicy fruit that tastes of lime. It can produce offsets and grow into a large cluster.
Bunny Ears
This is a must have prickly pear cactus for any collection. The pad-like stems of this cactus create offshoots that develop into a bush-like structure. The yellow dots on the stems of this cactus are glochids, or clusters of very fine barbs that cause irritation when touched, so this cactus requires caution when handling. Large, bright yellow to orange trumpet-like flowers sprout from the top of this cactus.
Lady Finger
Ladyfinger Cactus (Mammillaria elongata) (de Candolle): Tall, cylindrical cactus with a dense covering of short spines that can be white, yellow, or copper in color. This species from central Mexico can grow to about 6.0" tall and freely offsets to form dense clusters. It produces sweet, mini flowers of white, pale yellow, or pink and earned the Royal Horticultural Society's Award of Garden Merit.
