No one knows for certain who the parents were, so the hybrid Grevillea ‘Peaches and Cream’ lacks a species designation. (If it is important, the parent are most likely Grevillea banksii and Grevillea bipinnatifida.) It is an evergreen shrub that gets about four feet high and wide, with intricately lobed light green foliage. Individual leaves are about four inches long and two inches wide.
Four inch long floral trusses of tiny flowers can bloom at any time, attracting hummingbirds. Flowers bloom greenish yellow and then fade through a range of yellow, peachy orange and pink, from the bottom of the truss to the top. Warm and sunny exposure promotes bloom. Established plants do not need much water. Like other grevilleas, ‘Peaches and Cream’ grevillea can cause contact dermatitis. (It is best to know if one is allergic to it before planting it.)
Modern garden varieties of pampas grass found in nurseries are generally non-invasive. Their flowers are described as ‘sterile’, and therefore unable to produce seed. What that really means is that they are exclusively female, and unable to produce seed without male pollinators. However, they have the potential to be pollinated by naturalized pampas grass, and sow a few hybrid seed.
It could not have survived out in the desert for forty years. Wandering Jew, Tradescantia fluminensis, would have desiccated before its first summer. Well watered gardens are a completely different situation. Wandering Jew can become invasive and mix with other more desirable ground covers, only to die back and turn dark brown through winter. It starts over the following spring.
After many centuries of cultivation, myrtle, Myrtus communis, has not changed much. It was one of the more traditional plants for formally shorn hedges in Victorian gardens. It functions somewhat like a drought tolerant boxwood. Unshorn plants can grow as gnarly small trees not much higher than the eaves. ‘Compacta’ gets only about three or four feet high and wide, even without pruning.
No other big tree has trunks as sculptural as those of the California sycamore, Platanus racemosa. They bend and groove so irregularly, seemingly without direction, that it is a wonder that old trees in the wild eventually get a hundred feet tall. Some trees have a few trunks. The mottled beige bark is quite striking both in the shade of the broad canopy, and while trees are bare in winter.
There seems to be some discrepancy about the correct spelling of crape myrtle, Lagerstroemia indica. Many of us spell it as ‘crepe’ myrtle, thinking that crepe is the thin colorful paper that the flowers resemble. It is actually a rolled up thin French pancake. The thin paper is actually spelled as ‘crape’. Of course those of us who dislike the commonness of crape myrtle might omit the ‘e’.
‘Moonshine’ is probably the epitome of fernleaf yarrow, Achillea filipendulina, even though it is technically a hybrid. From the middle to the end of summer, its three inch wide corymbs (flat-topped trusses) of tiny bright yellow flowers stand as high as three feet above ferny and gray basal foliage. Bloom is best in full sun and warm exposure. Established plants do not need too much water.
