Opuntia humifusa [Long Island, NY] eastern prickly pear
An upright form of the eastern prickly pear, these have lighter green and more rounded pads than normal but
are just as easy in the garden. To under 1 ft tall these forms clumps to up to 3 ft wide. Lemon-yellow flowers
appear in mid spring, hopefully leading to dark red fruit in the summer. Hummingbirds love 'em; deer don't.
Garden water tolerant but good drainage never hurts in full sun to dappled shade. Frost hardy to USDA zone 5
or below.

Opuntia polyacantha 'Imnaha Sunset'
A Cistus introduction. These common natives of western dry lands have round to oval pads -- from 1-4" long
with dense, orange spines (polycantha means "many thorns) up to 2" long -- and form spreading mats to 4-12"
tall and up to several feet wide. Early summer flowers are, in this selection, yellow with orange stamens and
particularly abundant. Frost hardy at least into USDA zone 4.

Opuntia polycantha 'Citrus Punch' prickly pear
Another beautiful prickly pear from Colorado's Kelly Grummons, this spreading creature of under 1 ft in
height but eventually to 3-4 ft wide has orange and yellow spines and warm apricot flowers darkening with
age. Superb in rock gardens or containers and frost hardy to USDA zone 4 or below. Full sun and sharp
drainage.

Opuntia polycantha (hybrid) SBH 7523
This hybrid, O. polycantha x erinaceae v. columbiana x O. fragilis, discovered in the upper reaches of
Oregon's Imnaha Canyon, a particularly densely clumping plant producing abundant small pads that begin
deep green then add gray and white spines. The pads are rounded and somewhat easily detached, suggesting
its hybrid parentage. Flowers are an exciting lemon yellow with pink-tipped petals and orange stamens.
Cactus requirements -- lean soil, good drainage, and little to no summer water. Frost hardy in USDA zone 4.
Note: Do not shake violently.

Opuntia wrightii - white spine
Small cholla from northern Arizona and adjacent places, this collection has white spines rather than the silvery
spines of the genus. Tightly held branches form a miniature “tree” to about 3 ft tall. Greeny yellow flowers are
abundant in mid spring. Easy to grow in bright light and gritty soil with occasional summer water. Frost hardy
to USDA zone 4. A very good container specimen.

Philadelphus ‘Innocence’ mock orange
A most lovely form of the old-fashioned mock orange with particularly striking variegated leaves on this 6-8
ft, arching, deciduous shrub. Shared with us by our friend, Deborah Chaffee, the flowers are particularly
fragrant, noticeable at a great distance from spring through early summer and occasionally thereafter -- with
regular watering. Drought tolerant once established; sun to dappled shade. Frost hardy in USDA zone 4.
