I have been working hard, all week, in the sunken garden. It gets very overgrown during the summer during which time it loses its identity as a sunken garden as plantings become too bountiful. Some editing is necessary.
I am removing tired skullcaps which become woody with age. When I open up the space I find all kinds of seedlings vying for a spot in the garden. There are lots of bluebonnets and it is unlikely I will let them remain because their spread can reach over 3'. The ones I want to nurture are the blackfoot daisies, skullcaps and dahlberg daisies.
So many plants in such a small place. A fireworks gomphrena, columbine, asparagus fern, euphorbia, blackfoot daisies, all hoping that I will let them be.
Ghost plant, Graptopetalum, as managed to peak out from underneath the lavender cotton, Santolina chamaecyparissus. In front a coreopsis is hoping to escape the dreaded cobra head.
I like to have evergreen anchors at each corner of the upper level of the sunken garden. This spot has seen rosemary, A. desmettiana and recently the soft leaf yucca, Y. recurvifolia. Last year I removed the tall soft leaf yucca from this area. It left behind lots of offspring which I just left. They have now grown into a large cluster. OK for now. We'll see how they develop. It certainly looks healthy and as yet is untouched by those sap-sucking bugs.
I had no idea when I planted this Yucca rostrata, several years ago, that it was going to grow into such a magnificent specimen. It anchors this corner of the garden closest to the patio. See the Philippine violet to the right. It seeded here right on the very edge. I thought it died in last years cold winter but it it surprised me with its return. I doubt it is removable without destroying it so it will have to stay until such time as it becomes to large.
I first planted a crape myrtle in this spot. It grew too big. Then a dwarf Greek myrtle. It grew too big. Two years ago I replaced the myrtle with the spineless prickly pear and the squid agave, Agave bracteosa. This week I removed 15 baby squids and one teenager. The teenager was forcing the mother plant over so is much relieved by the loss of offspring. The teenager is planted in the fourth corner. I'm hoping it will survive the move. I also cleared out all the ruellia and heart leaf skullcap although I doubt they are gone forever.
Time to think about some companion plantings.
