My garden looks good right now, and will continue to produce cactus flowers, blooming shrubs and ground coverings until about May, depending how high the temperatures get. The Mesquite and Palo Verde trees are not very attractive right now as they are shedding last year's leaves and in preparation for new leaves, flowers and catkins. Around May 1, the Palo Verdes are in full bloom. It's always a spectacular show, but sometimes hazardous for the tree if the branches get too heavy with blooms. This sometimes causes the branches to split if the tree was heavily watered to produce fast growth. Weak wood is the result.
I love the way the papery bracts of the Bougainvillea appear translucent against the blue sky and bright sunlight. This is the cultivar, B. "Barbara Karst".
A field of Parry's Penstemon. The stems on this stand are quite tall, about 40 inches high. If it is too breezy, many of these long stalks will break or bend. It's been calm, so as of today, they are all upright.
This Lilac Vine is a new addition to my garden. My nurseryman said it will do well even in summer, but everything I've read says it's a shade plant for summers in Phoenix. Time will tell. Since the nursery guarantees all plants for a year, I'm willing to take the chance. I hope it makes it--I think the flowers, which appear only at this time of year, are quite pretty. The dark green leaves are also attractive.

Look how much this Agave stalk has grown in just one week. Scroll down to last Tuesday's post to see the difference! Although I've seen the unbelievably rapid growth of Agave stalks, I continue to be fascinated by the whole process. It's no wonder the Agave dies after producing this stalk. It takes tremendous energy resources to produce something this big this fast. The stalk is over three inches in diameter now and ten feet tall! It is now forming flower buds.
Notice the long flower coverings with sharp points. This is protect the buds as they are emerging. These eventually wilt and dry, exposing the flowers to pollinators like Hawk-moths, hummingbirds, wasps, bees, and butterflies. Bats prefer the branched inflorescence of other Agave species.
