2. R. ‘April Rose’ – [(carolinianum v. album x mucronulatum ‘Cornell Pink’)F2 x (dauricum v. album x dauricum)F2] Bright rose-pink flowers on a compact plant. Floriferous. Broadly branching upright habit to 3′ high. Reddish-bronze fall colour. A Mehlquist hybrid. Zone 5. (1 gal.)
3. R. cephalanthum – A dwarf species to 1′ high and spreading. Small, glossy, dark green foliage. It’s pale pink flowers are unusual in being narrowly tubular with spreading lobes similar to a daphne. Unique. Zone 6. (1 gal. – $15.00 or 2 gal. – $30.00)
4. R. ‘Dora Amateis’ (carolinianum x ciliatum) A very floriferous white (with a touch of pink) hybrid. Every spring it covers itself in flowers, hiding its dense, dark green foliage. Mounded habit. 30″h x 48″w. Highly recommended. Hopefully it will come this year. Zone 6. A few only. (2 gal. – $30.00)
5. R. litangense – A very dwarf species now lumped in with the more common R. impeditum. Very similar to R. impeditum in its tiny grey-green foliage and purple-blue flowers but it is very slow growing. Bronzy winter foliage. To 1’h x 1’w. in many years. Ideally suited to the sunny rock garden. Zone 5. A few only. (1 gal.)
6. R. ‘Northern Starburst’ – (tetraploid ‘PJM Compact’) A clone of this common hybrid that has been treated with colchicine to increase its chromosone count.

12. R. ‘Wren’ – (ludlowii x keiskei ‘Yaku Fairy’) Clear yellow flowers stand up like pansies above a creeping mat of shiny, dark green foliage. Bronzy-red winter colour. Free-flowering. At its best planted on a bank or in a raised bed. A beautiful and ever-popular Cox hybrid. Zone 6a. Another one that we hope to actually receive this year. (1 gal.)
ELEPIDOTE RHODODENDRONS
13. R. ‘Baden Baden’ – (‘Essex Scarlet’ x forrestii v. repens) One of many named varieties of this cross. Deep cherry red bell-shaped flowers with a waxy texture on a low growing plant to 2′ high. Upright spreading in habit. Shiny dark green foliage. Zone 6a but appreciates some winter protection. (1 gal.)
14. R. bureavii ‘Lem’s Form’ – A species with spectacular foliage. New leaves and stems are covered in rusty red hairs. Mature leaves are shiny green with thick rusty red indumentum. This selection has narrower leaves than the type species. Flowers are creamy white with crimson markings. Compact and shapely in sun, tree-like in shade. Mid-season. Zone 5. Hopefully we will receive the right one this year. (1 gal.)
15. R. ‘Casanova’ – (‘Newburyport Belle’ x ‘Good Hope’) A Leach hybrid with yellow, pink and orange flowers giving an amber-pink effect. Lustrous green foliage. Well-branched, spreading, mounding habit. To 4’h. Zone 5. We had more orders than plants last year. (1 gal.)
16. R. ‘Golden Gala’ – (‘Great Lakes’ x ‘Good Hope’) A proven performer in the Maritimes. Pink buds open to delicate pale creamy yellow flowers fading to ivory. Floriferous. Dense, glossy dark green foliage on a well branched, compact rounded plant. Wider than tall. To 4′ high. A Leach hybrid bred in Ohio. Zone 5. (1/2 gal. – $10.00 or 1 gal. – $15.00)
17. R. ‘Golfer’ – (yakushimanum x pseudochrysanthum) Perhaps the finest foliage of any hybrid. Silvery persistent tomentum and pale beige indumentum.

20. R. piercei – Early, tubular bell-shaped scarlet flowers grace this species. Well branched, rounded habit with dense foliage. Thick brown indumentum. Definitely tender in Zone 6 but of interest for hybridizing. Worth a try in the Yarmouth area. A couple only. (1 gal.)
21. R. recurvoides – Another species with exceptional foliage. Long, pointed leaves with heavy white indumentum aging to orangy-brown. Flowers are white or white tinged pink. Dense compact habit, 3-5′ high. Requires good drainage. Avoid hot sun and drought. Somewhat touchy in Zone 6a. A few only. (1 gal.)

25. R. yakushimanum ‘Ken Janeck’ – Somewhat larger and deeper pink than ‘Mist Maiden’ listed below. (1 gal.)
26. R. yakushimanum ‘Mist Maiden’ – If you were to grow only one rhododendron, this should be the one. Its long narrow leaves have a tan-white indumentum. New growth is covered in silver tomentum. The dense foliage covers a plant which is perfectly symmetrical and broadly mounded in shape. An added bonus is the rosy-pink buds which open to form large apple blossom pink trusses which fade to white. Slow growing to 4’h x 11’w in 30 years. Best in a half day of sun. Zone 5. (1 gal.)

DOGWOODS
51. Cornus kousa v. chinensis ‘Satomi’ – (Korean Dogwood) A small, shrubby tree, 15-20′ tall, for light shade. Multi-stemmed with a dense horizontal habit. This cultivar has breath-taking bright rose-red flowers with a creamy yellow eye. Blooms in early August, lasts for weeks, and is followed by raspberry-shaped red fruit. Bronze or crimson fall colour. Beautiful bark with age. Disease resistant but requires good drainage. Hardy to -32(C(-25(F). Sold out very quickly last year. A few only of the B&B size. (3 gal. – $60.00 or 90cm B&B – $75.00)
Cornus x rutgerensis – (florida x kousa) This could very well be one of the first introductions of these exciting hybrid dogwoods to Eastern Canada.

SHRUBS
55. Clematis ‘Asao’ – A beautiful late spring blooming variety. Petals have deep pink edges fading to near white in the center. Zone 5? (1 gal.)
56. Corylopsis spicata – (Winter Hazel) A much more civilized alternative to the early blooming but brash Forsythia. A 4-6′ high airy rounded shrub bearing pendulous clusters of small pale yellow flowers in early spring. Zone 6. (1 gal.)
57. Daphne x burkwoodii ‘Brigg’s Moonlight’ – For those that know and love the cultivar ‘Carol Mackie,’ prepare to be blown away by this exciting new sport – a reverse variegation. Almost evergreen leaves are golden-yellow with a narrow mid-green border. Its parent grows to 3′ high x 5′ wide – this one is apt to be smaller. Pale pink fragrant flowers open in May. Due to its high degree of variegation some shade may be required. A real show-stopper. Very slow growing thus the high price (our cost). We have been promised this but we aren’t holding our breath. Be sure to order it on the slim chance that we do receive it. Zone 5 or colder. (1 gal. – $30.00)
58. Kalmia latifolia ‘Little Linda’ – A new dwarf ‘Mountain Laurel’ selection with rounded leaves and a mounding habit. Red buds open to pink. To 3′ high in 10 years. Zone 5. (1 gal.)

60. Pieris ‘Brouwer’s Beauty’ – (floribunda x japonica) This light green, evergreen ericaceous shrub is much hardier than the more common Pieris japonica and intermediate between its parents in appearance. Flowers are more upright resembling P. floribunda. Airy red panicles of buds are held over the winter. Large panicles of small, lily-of-the-valley type flowers in spring. New foliage is glossy yellowish-green. To 6’h x 6’w. Zone5b. (1 gal.)
61. Pieris ‘Spring Snow’ – (floribunda x japonica) Another hybrid variety similar to ‘Brouwer’s Beauty.’ Zone 5b. (1 gal.)
62. Tsuga canadensis ‘Jervis’ – (Dwarf Hemlock) A very slow growing dwarf selection for the shady rock garden. Congested, dense irregular habit. Yellowish new growth. To 15″ high. Zone 5. A few only. (1 gal.)
63. Viburnum x bodnantense ‘Dawn’ – Dense rounded trusses of small rose pink, sweetly scented blossoms are born very early – in March when little else is in bloom! A vigourous deciduous shrub with an upright habit. Leaves are dark green turning reddish-purple in the fall. Flowers are frost resistant and are easily forced in winter. Zone 6. Not received last year. (4″ pots – $4.00 or 2 gal. – $15.00)
PERENNIALS
64. Corydalis flexuosa ‘China Blue’ – A selection of the species with cobalt blue flowers. Summer dormant in warmer climates this species will be in bloom for most of our growing season.

(1 gal.)
66. Hellebores x hybridus ‘Royal Heritage’ – (Lenten Rose) An aristocratic plant, this variety has rich reddish-purple flowers. Blooms very early in spring. Plant in light shade and prepare the soil extra deep incorporating plenty of compost and well rotted manure. Remove previous years foliage before flowering if tattered. Resents transplanting. Zone 6 or colder? A few only.
(3 gal. – $40.00)
66. Heuchera sanguinea ‘Splish Splash’ – (Coral Bells) Unlike most of the new varieties, this one has small leaves, a flatter habit and showy flowers. Leaves are heavily splashed with white giving a creamy effect. New leaves have a pink flush. Vibrant red flowers in late spring on spikes to 20″ high. Foliage 5″ high. Evergreen. Light shade required as it scorches in the mid-day sun. Zone 4/5. (1 gal.)
67. Tiarella ‘Inkblot’ – (Foam Flower) Semi-evergreen with panicles of small, fluffy flowers in spring. This cultivar is a clumper with large shiny leaves which develop a large dark blotch. Flowers are white with a pink tinge. For shade to part shade. Zone 5. (1 gal.)
