Editor's Journal: Stonecrop

A tropical fruit tree flowering in the Conservatory, a Hoya-like vine with the amusing name of Wattakaka blooming in the Pit House, a member of the Hydrangaceae family that blooms in blue when grown in acid soil, and a fuzzy-leaved Gesneriad blooming in the Alpine House complete our under glass tour. Outside, the Honeysuckle collection grown on the Honeysuckle walls is in full bloom, a Kalmia with buds the brightest red imaginable takes advantage of its perfect site, a very fuzzy Salvia is waiting to be planted in the Flower Garden, the diverse Alliums continue to dazzle, the Campanula walls are just that, and more. Continue.

Royal Horticultural Society Award of Garden Merit plants indicated by AGM.

The amazing flowers of the Guava tree are tucked in among the large shiny dark green leaves. What appear to be puffy petals, white on the outside and magenta on the inside, are actually white sepals bending back to reveal magenta petals. A center of red stamens with yellow anthers completes the flower. A Brazilian member of the Myrtaceae family.
Acca sellowiana
Dregea sinensis
A Hoya-like deciduous climber, also known as Wattakaka, this member of the Asclepiadaceae family is native to western China and is growing in the Pit House across the top, covered with hanging umbels of fragrant pinkish flowers. It's quite a sight!
A member of the Hydrangaceae family, native to the Himalayan foothills from central Nepal to China and Vietnam. Thick blue petals and blue stamens followed by blue berries--and like Hydrangeas, this plant must be grown in acidic soil for the best blue color.
Dichroa febrifuga
Sinningia canescens
Shown blooming a couple of weeks ago, this fuzzy-leaved member of the Gesneriaceae family from Brazil now has a few fully open flowers facing up--resulting in a better photo.
AGM
Just one of the many Honeysuckles blooming on the Honeysuckle walls. A member of the Caprifoliaceae family, this species has small tubular flowers.
Lonicera periclymenum sulphurea
Lonicera x tellmanniana
And another brilliant Honeysuckle, this hybroid has large flowers with a narrow bottom lip and a wide top lip.
AGM
Taking advantage of a site that must be perfect for growing Kalmia latifolia--the woods surrounding Stonecrop are packed with the native species--this cultivar with glowing red buds opening to pale pink flowers has been planted near the new entrance pavilion.
Kalmia latifolia 'Olympic Fire'
Salvia buchananii
Certainly one of the fuzziest Salvias, this species was found in a garden in Mexico City and is unknown in the wild. A member of the Lamiaceae family.
AGM
Although shown last week, these Alliums are now glowing in the late day sun. Known as the Star of Persia, it is native to Turkestan.
AGM
Allium christophii
Allium schubertii
The fascinating feature of this distinctive Allium is that each umbel seems to have two kinds of flowers--those on short stems and those on much longer stems. Native to Palestine.
This Allium, the second on this page from Turkestan, is distinctive also--its leaves are very broad the tight spheres of flowers are on such a short stalk the umbel seems to rest right in the base of the leaves.
Allium karataviense
Allium
A recently planted dark- leaved Canna--which must have been close to three feet tall when it was planted--and Allium hollandicum 'Purple Sensation' (AGM) glowing in the late day sun near one of the steeple trellises in the Flower Garden.
Long slender gracefully arching flower stalks on a shrub with narrow grey leaves. Native to China and a member of the Buddlejaceae family, the genus is named after Adam Buddle, an English botanist. Linneaus accidentally included the "J" in the name--and many of us, including the RHS, still use that spelling!
Buddleja alternifolia 'Argentea'
Campanula Walls
The stone walls of the raised beds near the potting shed are virtually covered with cascading Campamnulas, featuring C. portenschlagiana.
