Gardeners' Notes:

Technically, the botanical name for this plant should be:
Opuntia microdasys var. pallida 'Monstrose'
Because it has the "yellow" glochids, not brown, and it is a "cultivated" monstrose form.

This plant took well where I live. In its first year its grown 10 new pads. Its more of the most liked and noticed when I show my cactus garden to people. Like opuntias in general, it grows very fast!!

Oh and be careful when handling this plant!!

This Opuntia is one of the more ornamental Opuntia, grown primarily for its bizzarely shaped pads and golden for bronze 'fuzz' (which are actually itty bitty incredibly-hard-to-get-out-of-your-skin spines). Bunny cacti (Opuntia microdasys) are called that because all their spines are small. This monstrous form is Funny Bunny since it's also has twisted, very irregular pads. Unlike other Opuntia, it flowers rarely and the 'prickly pears' most Opuntia are known for are small and insignificant (don't know if they're edible or not). Like most cacti, this plant needs almost no water... but watering in the hot summers makes it grow faster. It tolerates the cold, wet winters of So Cal very well, as do most Opuntia, and it also tolerates a good deal of frost.

Bunny Opuntias are fairly slow growing and make excellent container plants for smaller areas.

It is easy to raise from cuttings, as are all Opuntia... just lie one on slightly damp cactus soil and keep it humid.. most root within a month.
